Have you encountered this situation? Open the Thinkpad T61 boot display interface, there is a black screen, what is going on?

       According to my observation, the common causes and solutions are as follows:

       1, there is no added or external hardware devices, if you have to remove these devices to see if the solution;                          

       2, boot press F8 into safe mode Use the machine to see if there will be crashes, if you have to save the important files formatted hard disk installation system to see if you can solv                                                        

       3, if you exclude the problem of the hard disk box system, it is certainly a graphics chip problem. Thinkpad Lane T61 an d R61 There T61P belongs to the graphics card door is the NVIDIA 140M graphics chip, you belong to the graphics chip, the problem is generally more and more serious, the machine motherboard chip is plastic, technical and equipment will not repair shop This plastic irrigation can not repair, the most important thing is technology. There are video door chips must be a new modified version of the chip to cure.

       4, the above can not be resolved, then directly call for sale.
