thank you very much for the scheme

but I need to ask for help it is the first edp screen I see and I don't know why the backlight does not turn on

I already checked the schematic but I can't find the fault, the only weird thing is on pin 1 and 2 it only gives me 7.5 volt
DISPOFF is not physically on the board
INVT_PWM is missing two resistors that do not come as in the schematic I am lost

I hope you can help me
and thanks in advance

Start a new thread in the main laptop forum if you want more help, and post a link to this thread so members can look at the schematic.

Is that .rar file working for anyone else? For me, the files just keep extracting into the mult-gigabyte range and never complete.

Hi.... nm-d031. How to disabale on board ram

Here are some information copied from other forum.

Good afternoon! If anyone is affected by the trouble of soldered memory in a lenovo ideapad 3 15iil05 laptop with an nm-d031 motherboard and there will be no money for new memory banks.
It is enough to solder 3-4 straps near the processor. Attaching photo.
