Lenovo x390 NM-B891 8th

Hi,

Lenovo Motherboard NM-891 8th

I have a motherboard without ic, I took from other board
MX25L25673G & W25Q80DV

I tried some files from forum, but the computer doesn't start, power button flash 3 times when I connect power but it doesn't start ...
I think the problem it's from EC data...

MX25L25673G with NeoProgrammer (sometimes I get error, like memory it's locked, but after many tries it works ...)
MX25L25673G with AsProgrammer

different programmers because they have them on their list ...

Does anybody has MAIN and EC bios dump both ic from same board?


Thanks!
Stefan

The EC chip on this is an SMSC MEC1663.You would not be able to backup or program that with a CH341A. The "W25Q80DV" chip is for the Thunderbolt firmware or something else.There are a few working bios you can try https://www.badcaps.net/forum/showpo...3&postcount=19

Re: need yoga x390 bios dump

I have an x399 that it came with corrupted bios.
I have write @electronica bios, but no luck, computer doesn’t start, but power button blinks 3 times…

Searching for error code on google, this means that it sense power adapter …(isn’t in sleep mode)
Can be that bios is not compatible?

Thanks!

this is NOT bios dump, it has 1Mb, look for bios chipset it should be 32Mb (W25Q256, MX25L256, N25Q256)
