This is the topic for the ThinkPad T460s. You can create a new topic for your request.

@hopkok : I rebuilt the bios again, combining the original bios and the bios extracted from the exe file downloaded from lenovo homepage. You have LAN problems possibly caused by a corrupted GBE region.

Hello hoaca388,
Please can you tell me how to merge original bios and bios extracted from lenovo downloaded exe file?
From what hexadecimal address to what other address should I copy and paste?

Re: ThinkPad T460s NM-A421 BIOS DUMP

hi guys
lenovo t460s
i had a supervisor password, i read and saved the winbond w25q128fv with the elnec programmer as w25q128bv because it was the only one on the list.
I tried with various files from this site but none works all the time black screen only for a moment when connecting the power supply the led on the button will blink (no beep).
I uploaded back my original file and same thing. I'm doing a write verification and it's ok.
Does anybody have an idea???
Misread file or something else?
I am attaching the read file

Hi guys, i reached this specific thread because i am struggling with a t460s that came untouched, but dead. Blinks 3 times, as if powered but no start at all. tried a dump from site, all started but, of course, delayed image and unaccepted WWAN device... made a Clear ME for it but now, the awesome error... "storage detection error on m2".... what should i do? i attach my original dump if anyone can help me on this, i would appreciate!
