How to Fix WIFI No Hardware Installed on MacBook

You may encounter an "X" icon in the MacBook wireless menu and a Wi-Fi drop-down menu that says "Wi-Fi: No Hardware Installed". Maybe it works after reboot few times, but Wi-Fi will never stay connected for a few minutes. This article will provide some solutions for how to fix MacBook no hardware installed.


Way 1: Reason for MacBook is Displaying "no hardware installed"

There is a simple solution to this problem. All you need to do is check the system management controller SMC. SMC helps control power management, battery charging, video switching, sleep and wake mode, LED indicators, keyboard backlighting and more.

When your MacBook enters/exits sleep mode, the SMC will decide which devices to turn off to save battery power and sometimes it will error. If the SMC has an error signal and believes that the WIFI adapter should remain powered off even after the MacBook wakes up after sleep mode, you will see the message as no hardware installed for wifi.

In this case, you should reset the System Management Controller to solve this issue. We offer three different solutions for the latest MacBook without are movable battery and older MacBook with a removable battery:

1.1 Built-in battery for MacBook

1. Connect your MacBook to a power

2. Press and hold Control + Shift + Option + Power simultaneously

3. Release all keys

4. Finally, press the power button to turn on your MacBook

1.2 MacBook with removable battery

1. Disconnect your MacBook from the power

2. Remove the battery

3. Press and hold the power button for five seconds

4. Install the battery on your MacBook

After all the above operations, try to reboot your MacBook to check the problem that MacBook does not detecting networking hardware.

Way 2: Reset NVRAM: Applies to all MacBook with Wi-Fi no hardware installation errors

NVRAM, also known as "non-volatile random-access memory" is a small portion of computer memory used to store certain settings in a location that mac OS can quickly access. The settings stored in NVRAM depend on the model of MacBook you are using and the type of device the MacBook is connected to.

Information stored in NVRAM include:

  • Speaker volume
  • Screen Resolution
  • Boot disk selection
  • Recent kernel crash information

Resetting NVRAM may be helpful when encountering problems with these parts.

How to reset NVRAM for all model:

1.Restart your MacBook and hold down Command + Option + P + R immediately,

2.Continue to hold down all keys until you hear the MacBook restart sound again, then release all keys simultaneously

Way 3: Apple Wifi Problems no Hardware Installed after Water Damage

If your network card fails to find hardware after repair or spill liquid, the problem may not be related to SMC, but to physical hardware. You can disassemble to reinstall it or replace the broken MacBook airport card.

MacBook Air 13" 2011 AirPort / Bluetooth Card Replacement as an example:

Step 1:

1. Turn off the MacBook before all. Close the screen and place it on a soft surface.

2. Remove the screws on the back cover.

Step 2:

Use your finger between the display and the cover case, then pull up to eject the lower case.

Remove the lower case and set it aside.

Step 3:

Disconnect battery connector.

To prevent accidental, disconnect the battery power from the motherboard. Grasp the clear plastic tab attached to the battery connector to disconnect the battery from the logic board.


Step 4: AirPort / Bluetooth Card

Use the spudger to lift the antenna connectors out of the socket on the AirPort / Bluetooth card.


Step 5: Remove the 2.9 mm T5 Torx screw that fix the AirPort/Bluetooth to the motherboard.


Step 6:Lift the AirPort/Bluetooth card and pull it out of the socket on the motherboard.


Step 7: Remove the broken AirPort card, replace the new original MacBook wifi card and reassemble your MacBook.

Way 4: MacBook Network Adapter has been Disabled

Maybe disable the adapter through the Network System Preferences Pane.If you click the Wi-Fi icon and the drop-down menu shows "Wi-Fi: Not Configured", it means the adapter has been disabled.

How to Reinstalling Network Adapters:

4.1 Start "System Preferences" and click "Network"


4.2 Select "wifi" and press the "-" sign in the bottom of the left and delete it

4.3 From the gear menu, select Make Service Active, click "Apply"

4.4 "x" will disappear from the Wi-Fi icon and your computer will scan the network and connect to a network


Still the wireless WIFI no hardware found on the MacBook?

If you reset NVRAM and SMC and still get a "Wi-Fi: No Hardware Installation" message in the Mac OS X drop-down menu, there may be physical hardware issues with the computer. May be motherboard or the cable fault after replacing the wireless card. This kind of fault is not easy to detect and repair. It is recommended to contact Apple after-sales service.

By the above method, I believe that you should be able to solve the problem that MacBook WIFI not working no hardware installed. If it still fails to connect, it may be a terrible thing. You can leave more message to discuss with us. More MacBook repair parts refer to GEMWON Global laptop repair parts Wholesale.

The Best Laptop Buying Guide for 2019 Student

Recently, many people are going to change their computer, so there are some concerns. What kind of laptop is right for you? You don't want the computer you just bought to find out that it was eliminated the next day. So how do you choose the best laptops for college students 2019?


Part1: Some Keys to Laptop Buying Guide:


Indeed, the heavy notebooks are not portable, but the thin laptops are portable? Unless the ultra-notebook is less than 1.3Kg, many notebooks are still heavy. For those who want to carry their laptops all day, ultra-portable is the best choice. Today, many laptops are qualified to be ultra-portable notebooks that provide a durable battery in a lightweight body without compromising performance.

14-inch screen is large enough that it won't affects movement. At this size, you usually get ports such as USB, type-C, Display Port and SD card slots. And 13 or 12 inches, generally only two USB port.

If you think you don't need to carry a laptop, feel free to use the 15-inch model. You'll get more powerful performance and more ports, but you may not want to pack such a large device into your bag. It’s still important to choose the size based on your needs for portability.

2.Select Screen

A lot of notebooks,1366x768 this pixel has been difficult to support the use of 2018 and 2019. If you buy such laptop with a budget as a student, it is best to have an external monitor. Even a 14-inch notebook is recommended for a 20-inch monitor. This will not cost much.

If you have a lot of games or graphic designs on your laptop, you must use a high-quality screen. You should look for panels with HDR support and at least full HD resolution. For those working in the arts, investing in a 4K screen is worthwhile.

3.Display Port Selection

Some people display to the external monitor use the VGA port. Most notebooks have mini DP or HDMI port,and the external display also has a corresponding interface. VGA interface display is not clear, jitter, lack of clarity, so not recommended for it.


4.Laptop Hard Drive Buying Guide

If you have higher running speed requirements. It is recommended that you choose to buy a computer with a solid-state drive and install an operating system on the SSD to achieve faster operation. Today's SSDs are becoming more popular and the price is no longer expensive for student.


The advantages of SSD:

  • Start fast
  • Fast random read, and minimal read latency. According to the relevant test: two computers under the same configuration of the computer, the notebook with SSD from the boot to the desktop took only 18 seconds, while the notebook with the hard drive took a total of 31 seconds, almost half of the two gaps.
  • Relatively fixed read time. Since the addressing time is independent of the data storage location, disk fragmentation does not affect the read time.
  • DRAM-based SSDs write speed extremely fast.
  • No noise. Since there is no mechanical motor and fan, the noise value is almost 0 dB when working.
  • Low-capacity flash-based SSDs consume less energy and generate less heat while operating.
  • There are no mechanical parts inside, no mechanical failure, no collision, shock and vibration. This will not affect normal use even at high speeds and even with tilting and tilting, and it will minimize the possibility of data loss when the laptop accidentally falls or collides with a hard object.
  • The operating temperature range is larger. A typical hard drive can only operate from 5 to 55 degrees Celsius. While most solid-state drives can operate at -10 to 70 degrees Celsius, some industrial grade solid state drives can operate at temperatures ranging from -40 to 85 degrees Celsius or even larger.
  • SSDs are smaller and lighter than comparable-capacity hard drives. But this advantage gradually diminishes as capacity increases. Up to 256GB, SSDs are still lighter than ordinary hard drives of the same capacity

5.Select Mac, Windows or Chrome

Some students want to buy a computer with a Windows system to reduce software incompatibility issues. But in fact, you can choose other operating systems. If it is not some special software, whether it is Mac OS or Chrome, it can meet the basic needs of college students to buy computers.

Most vendors offer price-specific offers for schools and include many software packages that can reduce the cost of buying a laptop for student in 2019.

How to Fix a Laptop Not Charging

If there is a problem with the battery charging, it is extremely inconvenient for people who need to work with their laptops outdoor. What should we do when laptop plugged in but not charging? Here are some reasons and solutions.


1.The adapter is broken and the laptop can't be charged

Whether the laptop not charged due to the power adapter is also very simple, the replacement method to test. This kind of fault is more common in DELL notebook.For example, DELL laptop adopts LBK (DELL architecture). The charging circuit design is quite special. If the adapter has problems, it will be plugged in not charging. And if it is not the original adapter, it will not be charged.

In HP's newer notebooks, there are some models that use this charging circuit. The classic failure is that the HP NX6400 CPU usage is 100% due to power error. For this reason, laptop charger won’t working, just replace the new original adapter to test.

2. Battery Damage

Battery failure performance is more obvious, the charging icon has been shown 100%. In fact, unplugging the power adapter it will continue to consume power quickly or can’t detect the battery. This is generally the life of the battery to the limit, we can judge this fault by calculating the battery life or the speed of battery consumption.

Tips: The notebook is always in a power-consuming state even when the notebook is turned off, to maintain the basic standby voltage on the motherboard. Once connected to an external power source, the battery will automatically start charging by default. To use the battery correctly, we recommend that the laptop be taken out of the battery for a long time, the battery power should be controlled at 40%, and stored at 15° Celsius or lower and charged once for about 1-2 months.

So, try another AC adapter and battery. Sometimes you can't find the same type of battery, you need to go to a professional laptop repair center for help.

The price difference between replacing the OEM battery and original battery is not very large, so the battery can generally be replaced directly.

The price of the original laptop battery is about one-tenth of the price of the laptop. The best choice is the original battery, which is safer in quality and life.

3.Laptop Not Charging Cause by Motherboard Problem

The notebook does not charge due to the failure of the motherboard is the most encountered in the repair of the notebook, because it needs to do chip-level maintenance.

There are two kinds of faults in the motherboard. From simple to difficult, the power port-circuit fault. This is relatively simple. The performance is that sometimes the battery is not powered down when the battery is not used, and the power is turned off when charging. There is also a connection between the battery and the motherboard that will cause anon-charging failure.

Then there is the circuit failure. Generally, the charging circuit and the protection isolation circuit are malfunctioning. Such as the common charging IC MAX1772, ADP3860 (the charging chip commonly used in the IBM model).

In addition to the chip itself is easily damaged, the damage of its peripheral circuits is also very common.There is also the EC itself and peripheral circuit faults, EC is the upper circuit of the charging IC, responsible for turning the charging circuit on and off.

Note: The detection of the causes of laptop not charging are more than the above. If your notebook also has this fault, you can read this article in detail.

BIOS (Basic Input/Output System) is the program that manages the connection between the operating system and the laptop hardware devices. Sometimes faulty BIOS settings can result in the laptop not charging issue. You can update your BIOS to fix the faulty settings.

This type of motherboard failure can be attempted to update the battery by firmware before being sent to the repair professional. Some notebook manufacturers embed battery correction programs in the BIOS firmware (such as ASUS), we can test whether the battery charging failure can be solved by updating the BIOS or restoring the BIOS default program.

4.Forced Hardware Reset for Laptop Saying Plugged in not Charging

4.1 If your laptop has an external battery, remove the battery and all external power adapter, press the power button for more than 15 seconds, then connect the battery and power to boot and charging.

4.2 If it is a built-in battery model,you need to remove the power adapter. Generally, there will be a small hole on the back of the notebook, called the "reset hole". You need to press the reset hole with a needle, then connect the power to the boot test to see if battery can be charged.

5. Laptop Plugged in not Charging Windows 10 Update

If your laptop can't charge to the battery, even if it is plugged in,

this is what you need to do:

5.1 Open "Device Manager" by searching for Device Manager or by right-clicking the Start button and selecting.

5.2 Click on the battery on the list to expand it and you should see two items: Microsoft AC Adapter and Microsoft ACPI Compatible Control Method Battery.

5.3 Right-click each item and select "Uninstall Device". Yes, you are uninstalling the laptop's battery driver, but don't worry, because it will automatically reinstall when you restart your laptop.


And the update is performed on the Windows update interface. In the networked state, the system will automatically download and install the adapted driver, and then restart after completion.


6. The Laptop Says 0% Available Plugged in Charging

6.1 Check whether the laptop settings disable battery, and some laptop battery management software or bios also has a disable charging function, you can check it.

6.2 If your laptop battery is hot to the touch, excess heat may interfere with the charging process. Turn off the computer and let it sit for a few minutes to cool. If you have not cleaned the vents of your notebook recently, blow a can of compressed air at a certain angle (for a short time) into the fan vents to remove some dust. It may also be because the battery has been left unused for too long, resulting in poor contact. It is recommended to open the laptop to clean the dust, plug the power adapter and the battery, and use the professional cleaning tool to clean it in the interface. It may also be solved.

6.3 If there is no problem with the inspection settings, then most of the battery internal control cables or batteries have problems and need to be repaired.

6.4 When some laptop batteries have been used for a long time, over-discharge,resulting in the 0% available power has been connected to the uncharged. It is best to buy a new laptop battery to replaced.

7. When Battery is Charging Stuck at a Number and Cannot be Charged to 100%

This may be due to some settings in the power management software. For example, the ThinkPad's power management software has the option to set the battery charging threshold. This option can better maintain the battery life. So, if you have other battery management software, when there is a battery not charging laptop, you should check the power management software first, or uninstall him to test if the problem is solved.


8.Reset Windows System

If your battery is new and none of the above solutions solve your problem, you will need to try resetting the Windows 10 system. Because this operation requires you to backup all your data, and it will have a big impact, so it is recommended only if all the above methods are invalid.

If reinstalling the operating system still does not solve the laptop battery charging error, then refer to the possibility in the above the 3 way, you need to send the computer to the repair store to repair the motherboard or the circuit.

The Bottom Line:

The computer indicates that the power has been plugged in, but the battery has not changed. Most of the failures are caused by the battery life. You may need to purchase a new battery for your laptop. Before purchasing, please try whether you can solve the laptop not charging even with new battery according to the above method.

Part 1. The Reason Why the Laptop Has no Sound

The sounds card driver is usually caused the laptop has no sound after update; the hardware failure is caused by the sound card device being disabled or the sound card is damaged.

Part 2. How to Fix No Sound on Laptop

1. Reinstall sound card driver

If you have already tried some checks, make sure the "mute" button is not turned on, the speaker volume is turned up, and the speaker is selected as the default play device. However, your laptop no sound but not muted. Next you should try to reinstall the audio driver.

Finally, test whether the audio not working in windows 10 is resolved.


2. Restart your laptop

If you are experiencing sound problems, try restarting your laptop and see if it solves the laptop no sound problem. Many times, if your system has been running for a long time, rebooting can clear some strange problems. For other devices such as mobile phones, this is often an effective method.

3. Confirm that the default play device is not the other

For example, if you have a video device that with HDMI and you connect to laptop, your laptop sounds may disappear because the HDMI port became the default audio play device. You can change the speaker to the default play settings by going to the "control panel" and "Hardware and Sound".


4. Try the Microsoft 10 Troubleshooters

  • Enter "Troubleshoot" in the search bar
  • Open the "troubleshoot"

5. Confirm bios settings

Sometimes sound devices are disabled in the BIOS, so anything you do in Windows has no effect. Or the laptop has made some updates and the sound suddenly stops working, you need to go to the PC manufacturer's site and download the latest BIOS for your computer.

Part3:Actual Case for Notebook Hardware is Faulty and There is No Sound

Speaker no sounds because fall and water damaged, which usually requires professional technicians to repair.

Lenovo B470 laptop no sound repair case:

This Lenovo B470 notebook speaker and headphones have no sound, and updating the sound driver is useless. I replaced the solid-state drive of the win 10 system, and the system showed "no speakers or headphones inserted."

It is good to find the speaker. This machine has a small board, connected to the main board through the cable, open the drawing 10250-2, all the sound signals on the line are not found to have a short circuit, and there is no voltage during the power measurement.Temporarily exclude small plates.

Removing the power amplifier chip that may affect the sound output and the expansion card chip on the small board, the fault remains.


The connection resistance of the line was not found to be corroded, and it was connected to the sound card. The resistance and the bridge also had a value of 450. However, the blower bridge was tried and the bios was updated, and the fault remained.

In addition to the bridge, there is a small board left. After installing a new sound card board, there is a sound. It seems that the board is broken.

In win 10, the real sound card device is"Realtek High Definition Audio". The device that was misjudged before is said to be an HDMI audio module.

The system displays "no speakers or headphone". The headphone jack is not detected. Because the speakers are turned on the power amplifier and the amplifiers are ok, there is only a problem with the headphone jack.

Reconnect the fault board and test all signals to find the true point of failure.



Usually the sound error is caused by audio driver or software conflict. You also need to check the settings of the sound card hardware to ensure that it is not disabled. If the sound card board or interface board is broken, it may cause the laptop has no sound even with headphones. This situation can be purchased at GEMWON to get the professional repair parts.

How to Dispose the Wi-Fi Not Working on MacBook

Let's imagine that when you take a group of beautiful photos and then prepare to use your MacBook to log in to Instagram to upload photos to share your life, you suddenly find that Wi-Fi Not Working on MacBook, I believe this can makes you feel crazy, but don’t be worry, we will fix it in no time, so why won’t your MacBook connect to Wi-Fi? Let us see the article below.


Most of us take an always-on wireless internet connection for granted: we're used to it being there when we need it. Unless you're particularly unlucky and plagued by broadband problems, or live in a remote part of the country, fast access to the internet, allowing the streaming of audio and high-definition video, is the norm.

When things go wrong with your Wi-Fi or your broadband connection it's not just your email you'll be missing, but also your social networking life and your evening's Netflix viewing. Equally, if your MacBook has a slow internet connection you can find yourself tearing out your hair.

There are three main reasons why safari no internet connection MacBook: there's a problem with your router, your broadband provider's network is down, or there's an issue with your own Wi-Fi network. Less commonly, there may be an issue with the macOS software you're running. We cover all these scenarios in this article.

Preparation: First, determine what the issue is. Knowing what's wrong will help you identify appropriate troubleshooting steps of MacBook won't connect to Wi-Fi.

1: Dose the Symptom Occur with More than One WI-FI Device

Wi-Fi issues may be related to the network in question or they may be related to the Wi-Fi computer joining that network. Usually, if other computers or devices(such as Apple TV or iPhone) can get on the Internet without issues, then your Wi-Fi router is probably fine.

If you only have one Wi-Fi device, proceed with this article.

2: Make Sure Your Software is up to Date

Install all software updates available for your MacBook.

If you use a third-party Wi-Fi router, check with the manufacturer to confirm that it has the latest firmware installed. If an update is available, follow the manufacturer's instructions for updating the firmware.

To determine if your Apple Wi-Fi base station firmware is up to date, see Updating your software.

3: Check Your Connections

Some networking issues may be caused by loose or disconnected cables. Verify that all Ethernet and power cables connected between your modem and your Wi-Fi router are correct. Checking that devices such as your router and modem are on,disconnecting and carefully reconnecting Ethernet cables, and replacing damaged Ethernet cables may resolve the issue without any further troubleshooting.

4: Verify that You are Using the Recommended Settings for Your Device

See Recommended settings for Wi-Fi routers and access points.

If your safari, email program, or any of a hundred other Internet-connected apps on your MacBook Pro starts complaining about not having a connection, you may have to do a bit of sleuthing to figure out the cause. After all, a disruption any where along the chain between your MacBook and a distant server could cause an outage,and it’s not always obvious where to look.

I suggest trying each of the following steps,in order, until you’re able to connect again.

Operations:Secondly, take action to solve the problem of no internet connection MacBook.

1. Try another Site or APP

To make sure the problem isn’t restricted to just one website, try visiting another—preferably one that’s highly reliable, such as

Similarly, to make sure the problem isn’t just your current app (such as your email program or Web browser), try connecting to the Internet with another app. If only one site seems to be having problems, try visiting Down for Everyone or Just Me and entering the problematic site’s URL. The service will tell you whether computers elsewhere on the Internet can successfully connect to the site.

2. Use Network Diagnostics

Certain types of network problems may cause your browser to display a Network Diagnostics button. This is OS X’s way of offering to help debug your connection problem, and I suggest accepting that help. (If you don’t see a button, you can launch Network Diagnostics manually. To do this, choose Apple menu > System Preferences and click Network.Click Assist me, and then click Diagnostics.)

The Network Diagnostics utility will guide you through a series of questions and tests,ranging from checking your ethernet or Wi-Fi connection to network configuration and DNS servers. Sometimes the utility can repair problems itself; when it can’t, it usually provides more detailed information about the nature of the problem and offers suggestions for solving it.


The Network Diagnostics utility built into OS X can track down, and sometimes repair, network connection problems.

3. Nudge WI-FI Back to Life


Check your Wi-Fi menu to make sure you haven't gotten onto the wrong network.

If your MacBook connects to the Internet via Wi-Fi, check the Wi-Fi menu (at the top right of your screen) to make sure you’re connected to the network you intend to be. MacBooks have been known to hop onto less-desirable networks at inconvenient times.

If the menu’s icon has an exclamation point, indicating that it can’t successfully connect to any network, try choosing Turn Wi-Fi Off from the menu, waiting about 30 seconds, and then choosing Turn Wi-Fi On.If that still doesn’t work, restart your MacBook. Sometimes that’s the only way to clear wacky errors that prevent Wi-Fi from connecting.

4. Try Another Device

If you have access to another computer or mobile device that uses the same Internet connection, check to see if you can connect to a website on that device. If not, you can at least rule out your MacBook as the source of the problem and look elsewhere for a solution. But if the other device can connect and your MacBook can’t, even after a restart, skip ahead to the step "Check your DNS settings".

5. Reset Your Router Reset

For network problems that lie beyond your MacBook, if you own or control the network device your MacBook connects to (such as an AirPort base station, Time Capsule, router,switch, or hub), turn that device off, wait about 10 seconds, and turn it back on again. Wait for it to power on completely (sometimes a multi step process that can take several minutes) and try connecting again.

If there’s more than one such device between you and the Internet—for example, an AirPort Express connected to a cable modem—start with the one closest to the Internet and then work your way back to your MacBook, cycling the power on each one as you go.


6. Check Your DNS Settings

The Domain Name System (DNS) enables your MacBook to convert domain names ( into IP addresses (like If the DNS server your MacBook uses is offline, slow, or faulty, you may be unable to connect to any site or service by name. Here’s an easy way to check whether DNS is functional if no websites, such as, respond. In your browser, type in this URL: should bring up the Google website. If it does, then you know your Internet connection itself is fine and the problem is merely looking up domain names.

To fix that problem, open the Network pane of System Preferences and select your network connection in the list on the left. Click Advanced followed by DNS. In the DNS Servers field, you should see one or more IP addresses. If those addresses are enabled (black, as opposed to gray), select each one in turn and click the minus-sign (-) button. Then, regardless of whether there are already addresses there in gray, click the plus-sign (+) button and enter;repeat with addresses point to Open DNS, a free DNS service that’s often more reliable than the default servers your ISP uses.) Click OK and then click Apply. Now try connecting again.


If you suspect a DNS problem is preventing you from connecting to the Internet, try entering the IP addresses for the Open DNS servers, as shown here.

Even after following all these steps, success isn’t guaranteed, because some outages could be beyond your control. Because of the distributed nature of the Internet, an equipment failure at an ISP can affect more than just that ISP’s customers. And on a larger scale, accidental damage to a major fiber optic cable can (and occasionally does) wipe out Internet access to a large region.So, sometimes the only solution to an Internet outage is to wait for it to be fixed. But if the problem lies beyond your local network, your ISP should at least be able to tell you the nature of the problem and an expected repair time.


Hope you know how to dispose MacBook Pro won’t connect to Wi-Fi after reading this post. If this post really helped you, don’t forget to share it with your friends. If you still have any further questions, please leave us a message below.

The high level of integration makes it difficult to repair and the maintainability is getting lower and lower. However,as long as we have mastered the good method, it is not difficult to solve the problem of the Laptop motherboard repair. Then I will introduce the classification and troubleshooting of the laptop motherboard failure in detail.At the last of the article, I will show you the skill of Laptop motherboard replacement.

Signs of laptop motherboard problems:

1:Failure to boot

2:Blue screen errors

3:Randomly freezing and hardware no longer works

9: Liquid damage

10:Overheating caused my fan failure

11: Physical damage


Common method for laptop motherboard repair:

The motherboard failure often manifests as a failure phenomenon that is difficult to visually judge, such as a system startup failure and a screen display. The laptop motherboard troubleshooting methods listed below have their own advantages and limitations, and are often combined.

1. Cleaning method: The dust on the main board can be gently brushed with a brush. In addition, some cards and chips on the main board are in the form of pins, which often cause poor contact due to oxidation of the pins. Use an eraser to remove the surface oxide layer and re-plug it.

2.Observation method: Repeatedly check the board to be repaired, see if the plugs and sockets are skewed, whether the resistance and capacitance pins touch each other, whether the surface is burnt, whether the surface of the chip is cracked, and whether the copper foil on the main board is blown. Also check to see if any foreign objects fall between the components of the motherboard. In the case of doubt, you can use the multimeter to measure it. Touch the surface of some chips, if it is abnormally hot, you can try another chip.

3. Resistance, voltage measurement method: In order to prevent accidents, should measure the resistance between the power supply+5V and ground (GND) on the motherboard before powering up. The easiest way is to measure the resistance between the chip's power pin and ground. When the power plug is not plugged in, the resistance should be 300Ω and the minimum should not be less than 100Ω. Then measure the reverse resistance value,slightly different, but not too much difference. If the forward and reverse resistance is small or close to conduction, it indicates that a short circuit has occurred and the short cause should be checked.
