e540 NM-A161

[fsousa]

Hi,

I am looking for BIOS files for my laptop, a Lenovo e540 with AILE2 NM-A161 Rev 1.0 board.

Currently the laptop won't show anything on screen, won't POST.

All my searches lead me to winbond dumps, but my board has cFeon QH64-104HIP and cFeon QH32-104HIP, identified by flashrom as EN25QH64 and EN25QH32.

I am assuming that it is not safe to load winbond BIOS to cFeon/EON.

I am attaching the current dumps.

Hope anyone can help me fixing this BIOS.

Thank you,
Filipe

Sorry for the missing info and info misplacing.

The model/type is a 20C6-00LLPG and SN PF05CB9H.

The board part number/FRU is 04X4949 by vendor HannStar with date 2013-12-12.

If there is any relevant info that I should provide, I'll be happy to do it.

Thank you,
Filipe

Thank you hoaca388.

I flashed both U4M1 and U8M1 chips. It made no difference on laptop behaviour.

Tried to flash also the USROM1, however I was unable to do it, not shure if it was my programmer issue, or just me doing something wrong.

I don't know if it is a relevant behaviour or not, but when I power on the laptop, the fan spins for some seconds and turns off. Spins back again and then stops spinning. Next time the fan spins it wont stop anymore.

No beeps, no blinks nothing.

Any hint would be great, thank you!

Thank you volinakis It worked!

I was not confident that a BIOS loaded from windbond would work on cFeon/EON!

Thank you volinakis and all badcaps community!
