Lenovo IdeaPad 3 15ADA05
model 81W1
SN PF236DLK
mtm 81W100KHSP
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.Comment

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.Comment

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. ThanksComment

So a couple of years ago i got a bios update through Lenovo Vantage, so i installed it and bricked my whole BIOS, so i couldn't fix it so i put that ideapad in a box, 3 years later i found that one PC and want to recover it to switch from a 2014 hp laptop to this one.
I found a method to recover the BIOS of many lenovo laptops tha consists in pluging in a USB Flash with the BIOS files and power on the laptop with Fn + R keys pressed until fans go loud and start beeping loud, but nothing worked, so i think filename is wrong, i tried naming the bios file as 07WW.BIN, BIOS.BIN, BIOS.fd,...10-11-2024, 03:12 PM -
