Good day,
I have a motherboard from a Lenovo legion 5 laptop. The previous service was unable to repair it. So I started the repair myself. The motherboard wouldn't turn on at all. The problem was in the mosfet in the PU101 which starts the power supply and in the PQ8203. And in the burnt Lenovo IT8227E chip and also in a short circuit in the power supply. I fixed and replaced everything. I have the same parts board. Now the board turns on and the battery is charging, the power button lights up green. But I am not getting the image. And the board turns itself off in approx. 25-30 seconds. Could the problem be that I used the Lenovo chip IT8227E from another board that I had for parts? The repair and parts board is the same NM-C911 rev 1.0. Only the graphics cards are slightly different.
repaired is: N18E-G0-A1 vs N18-G1-B-KD-A.
Why does the board turn itself off after 30 seconds? Capslock flashes when turned on.
And where could there still be a problem?
