Hi, please find attached a picture with the mobo markings (NM-D711 rev 1.0) and the schematics. Unfortunately I´m quite inexperienced with electronics, can you provide some instructions on how to test the power rails? The mobo is Intel and the bios chips are 3.3V in fact i was able to flash them with a known working bios but the problem persists.
Thanks!...

Hi, I wonder if anyone can help me fix my Lenovo Legion 5 (15ITH6H) laptop. Basically, after a windows update the computer would not boot anymore. When powering on the laptop the screen has no backlight and nothing would show up, using an external monitor did not help. However, the laptop would still spin up the fans and turn on the keyboard backlight. The keyboard backlight intensity function key would work and the power button led and the charging led are also working. I've tried every possible combination of key press and power button hold down time but did not change anything. At this point...
