Re: Lenovo IdeaPad 3 15ADA05

Hi there. Such a problem
After updating my laptop ... The WI-FI adapter disappeared everywhere and the keyboard does not work at all in Windows itself. Everything works in the bios itself. Changed the update from the site, it did not help.

Product Name: Lenovo V15-ADA
Bios Version : E8CN36WW
EC Version : E8EC36WW
MTM: 82C70065CK

Please help me

Upload your BIOS Backup here (even if it's corrupted) and write your Device Serial Number.

Why did you give me this file! I said your BIOS Backup, the file that was in your BIOS Chip.

Are you familiar with BIOS Programming through Hardware Programmers (SPI)?
If you are not, read that Post to learn.

You should upload your Original BIOS Backup here, in order to transfer the DMI from it to the New BIOS.

Re: Lenovo IdeaPad 3 15ADA05

Sorry here is the backup bios file

Re: Lenovo IdeaPad 3 15ADA05

Sorry here is the backup bios file

the bios must have 8MB not 1MB... look for a bios chip on the board, copy the content and post...

I'm sorry but it always returns a 1 mb file, and when I do a test it indicates that it doesn't find any manufacturer in the database, would it be possible to put it manually?
If yes could someone help me to get the bios backup, by tweezers onboard with CH341A software ver. 1.34.
My chip is 25Q64JWSIQ
I saw somewhere on the internet that you could create a manual entry in the program, but it asks for a Chip ID that I don't know where to find

The 25Q64JW is a 1.8V chip. There is a lot of info about the CH341A https://www.badcaps.net/forum/showpo...40&postcount=2 .

Re: Lenovo IdeaPad 3 15ADA05

I have tried a few of the BIN files posted here (#1, #29, #38), and none of them are working for me. It still gives me the same problem. Black screen, nothing happens, tried many key combinations, USB booting, etc.

Unfortunately I do not know the serial number (the sticker on the case seems to have been taken off), but I have attached my corrupted BIN file I read from the chip. I don't really mind if it's different. If anyone could help me with a working BIN or what other issue my laptop has, I would be ever so greatful.
