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.

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

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. thank you very much for the scheme

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.Comment

Re: schematics for nm-d031 motherboard
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.Attached FilesComment

My laptop died on me about two years ago. I went through the basic recovery steps a few times and eventually, after plugging the battery back in for the xth time, a capacitor blew up on the board. Weirdly enough, the laptop then booted (battery removed) and has been running without issue ever since.
I'd eventually like to examine the board in detail however I've had zero luck searching for schematics/boardviews for my particular motherboard.
Any help would be greatly appreciated.

I think it would be dumb to toss a "modern" motherboard just because a resistor got scraped off, so here I am. I am hoping to find the right schematic so I can see if the motherboard can live without 1 of 3 60B SMDs in series likely scratched off by the backplate of a PCI-E card install or removal. It could be related to a functionality that is not needed or critical, or it could fry anything I plug into it and power on. If I could find a replacement, I could likely pop in on the board, but if I don't need to, then screw it, I don't mind leaving something dark that doesn't matter....07-06-2025, 02:00 PM -
Thank you for deciding to read this topic!
Laptop: NP700Z3A-S02RU
Motherboard: BA92-09470B
I was trying to fix my old laptop that has stopped displaying image a long time ago. It boots up, lights light up, fan spins but no image. Conned it to TV by HDMI cable, but it was unsuccessful. Components look intact, no water damage/corrosion on the board.
I don't really value this laptop too much, so I wanted to ask anyone for a schematic/boardview file or anything that describes motherboard in a simillar faison. I want to experience a challenge of figuring... -
Dear friends,
I’m currently looking for the schematics of the ASRock C3558D4I‑4L motherboard. If anyone has a copy or knows where I can find it, I would really appreciate it if you could share it with me.
Thanks in advance for your help!...07-18-2025, 11:03 AM -
