            I need a schematic for Lenovo IdeaPad GS454/GS554/GV450/GV550

            I need schematic for boardview for Lenovo IdeaPad GS454/GS554/GV450/GV550 NM-D031 REV:1.0 board,
            display does not have a backlight and I tried it on another computer and it works correctly, so the problem is in the motherboard.
            I hope you can help me

                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.

                      Re: schematics for nm-d031 motherboard

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

                          It extracts ok with 7-zip

                              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.

                                  @Lisa Su-Have you personally tested this strap config to disable onboard ram on this platform?? I dont have such a board in repair now with me,so not able to test it.
