I recently received a faulty notebook Dell Inspiron 15-5000, and customers reported frequent notebook crashes,There is no water, there is no collision, this is how it happened?

       Based on my experience, I suspect that there is a high probability that this condition is caused by insufficient power supply to the Dell Inspiron 15-5000 notebook CPU. But do not rule out other conditions, so I first tested and found that the default client notebook CPU operating voltage of 1.5V. However, the operating voltage of the CPU that was booted into the BIOS was only 1.2V. It seems that my previous inference was correct. The reason why the laptop computer often crashes is definitely caused by insufficient power supply of the Dell Inspiron 15-5000 CPU.

       This is due to aging of the components of the Dell Inspiron 15-5000 motherboard, which caused some of the voltages to be low,CPU naturally does not work, it crashes also inevitable. Just like overclocking, the CPU after raising the frequency will not be very stable, and some need to increase the voltage to stabilize at a higher frequency,Like this reason, in fact, a considerable part of the notebook computer failures and power related.

       How to deal with the problem after it found?

       There are many reasons for the lack of power to the Dell Inspiron 15-5000 notebook CPU. First, we should check that the machine's power supply match. The reason that the author encountered a lot of machines can not start or instability is caused by the power directly. The first thing we should consider before checking the power supply is whether we have added any accessories for the computer. Some branded machines have the same power supply as the system's total power. Adding new ones will probably cause the power supply to run out of power.

Therefore, if new accessories are added, try removing the device. If it does not work, then we must consider whether the electricity supply is stable. There are also problems with unstable electricity supply in some places. If so, you may want to install a voltage regulator.

       In addition, the installation of an external device such as an excessive number of notebook USB devices also consumes a lot of power and may also cause system instability.

       If there is no problem with the power supply, the problem usually occurs on the motherboard. Only check if there is any capacitor damage on the motherboard. If it is damaged, replace the motherboard. There is a difference between each laptop model and different brands of notebook motherboards. This requires a clear understanding of the changes.
