Re:ThinkCentre: Failed uEFI / BIOS update. Two 2 beeps. Is there any hope?

2020-05-19, 2:21 AM

I had a seasoned IBM tech here a few weeks ago to do some Lenovo repairs and asked him about this.  He took a quick look and confirmed that from his experiences, once a BIOS upgrade fails like this, the system board is damaged and can not be re-flashed.  Unlike with HP and Dell, I am reluctant to do firmware updates on Lenovo computers knowing I can brick them.

Just to finish my story. I was able to revive my M92p after a bad BIOS flash. In my case even boot block recovery didn't work.

 

So I used a ch341a BIOS Programmer and flashed the BIOS CHip directly and was able to rescue my system.

 

Lesson Learned: Don't use windows based BIOS flashing tools.

Also while I was able to save the Board with a 5$ BIOS progarmmer, all the time I wasted doing this was not worth it. Just throw the board away and get a new one.
