Hello, I've tried to find it by dumping different BIOSes that you provide, reading several posts without success. The laptop stayed with a black screen after updating the BIOS and it remains like that... I would appreciate it if you could help me please.

New bios

I have dumped the BIOS you sent me with asprogrammer, putting the delete/write/verify option with the result ok, but I still see a black screen, the portal turns on, moves the fan, but still does not give an image, somewhere I am failing but I do not see it...

Hello, these BIOSes are 100% compatible with AMD CPUs. This means you have a different issue.
You can try these steps.
1- Try using an external monitor.
2- Shine a bright light on the screen and see if there's any image on the screen. This could be a backlight issue.
3- If you have a graphics card, the problem could be related to that.
4- If you have an SVOD 4 programmer, program the IO EC. I have the EC BIOS in my post. You can download it from there.
5- Test the LVDS EDP cable connected to the display.
6- Remove the battery and adapter and hold down Ctrl+Alt+Esc for 15 seconds. Then hold down the Power button for 15 seconds. Then, swap the RAM. Then, reconnect the adapter and try turning it on. It should probably display.

Hello! By the way, thanks for your help. Nothing, none of the options you told me about worked, always a black screen. I was sure it was a BIOS problem because it happened when I was updating, on the first reboot it started updating the BIOS and completed it, rebooted again and verified with 4 or 5 lines all ok, and when it rebooted again it was left with a black screen... but if you tell me that the BIOS that hoaca388 gives me has to work, I don't know what to do anymore... I'm dumping the BIOS with asprogramer-dregmod-v3.17 selecting the W25Q64JW-IQ_1.8V chip (WINBOND) through a CH341A programmer, connecting the 1.8V adapter to the programmer and the BIOS chip to the adapter. In case I'm doing something wrong... although it doesn't give me errors either when I dump the BIOS or when verifying. Thanks

Hello. The "NM-C821 DUMP" post on the site shows a corrupted picture and then remains black, but it won't open again. Attached is the E8CN18WW picture. I downloaded the bios from another site and changed it to E8CN28WW. The picture improved, but it booted once and then wouldn't boot again. Then I found this thread and did as instructed, but no picture appeared. Attached are the files. Did I make a mistake?
(There is no picture in my original bios backup) There is no label on the case. When I opened the BIOS from the website (by copying the DMI), I wrote down the serial numbers in the attached picture.
