P15 Gen 1 (type 20ST, 20SU) Laptop (ThinkPad) - Type 20ST needs the main BIOS and video. The client says that after the Windows updates there was a firmware update and after that the device makes the sound of music when there is no screen. Moreover, if you turn it on several times then the picture sometimes appears and it works and passes all tests (wonder)
and may even reboot normally a couple of times
Now he doesn't want it anymore, no matter what I tried
It helped to change the video cable a couple of times, I ordered a new cable, it didn't help
Of course I checked the fuses and installed the screen
