Hello Everyone, I suffered a BIOS upgrade issue and now my laptop is dead...
I was able to fins the UC8M2 chip closer the CPU and besides is there is a similar chipset, is this the UC8M1 ? because it is not labeled in the board. Both are Winbond 25Q64FVSIQ

My intention is to re-write both with different files from this post.

Thanks in advance !

If that is your intention i would recommend you make some good backups first, just in case something goes wrong

If someone could confirm the other is the UC8M1, or where it is located I would really appreciate !! 😉
I assumed it is due to the chipset model, as I could check in the schematic document. Also I followed the schematic connections for the UC8M1 pins and it looks to be it.

Just to add, Laptop is L460
TYPE: 20FV-S1BF06
SN: PF-0S51WJ

I´m reading again the whole thread to understand the best process. Thanks all for the information you have shared.

SMDFlea could you validate the files ? Today I received the programmer and I´ve read the chipsets

Hi, i have the same problem, power on but black screen.
The BIOS was supposedly updated by the service, but the issue persisted. Now, I am going to try updating it myself.
Does anyone have functional BIOS files available?

Hello.

My Lenovo L460 has a problem with a black screen. I have already checked that it is a problem with the BIOS. I have uploaded the BIOS from post #27 but this BIOS shows problems with the LAN card. I need the card for work. Can someone help me repair my original BIOS to make the screen work again or modify the one from post #27 so that my LAN card works with this BIOS?
