Hi

I have -> ThinkCentre M57 (6072-A5G).
The Machine was crashing, power off, during the BIOS upgrade and it was not completed.
Now I'm getting a black screen.

I've tried to reset using the BIOS jumper on the motherboard, but still doesn't work.
Has someone any idea howto solve this problem?

Maybe we'll be able to get the board into recovery mode but for that we first need to find out if it's AMI/Award/Phoenix/Insyde bios we are dealing with. I'll try and find out if the bios chip is removable too, if so, you can use an online service for sending you a preprogrammed chip.

I've done according to:

http://download.lenovo.com/ibmdl/pub/pc ... 5c6524.pdf

and the BIOS is recovered now.

Code:
Recovering from a POST/BIOS update failure

If power to your computer is interrupted while POST/BIOS is being updated (flash update), your computer might not restart correctly.
If this happens, perform the following procedure commonly called Boot-block Recovery.
Note: If your computer has no internal diskette drive, an optional USB diskette drive must be connected to use the BIOS flash diskette.

1. Turn the computer off and insert the BIOS flash diskette in the diskette drive.

2. Turn the computer on and immediately press the Ctrl and Home keys (Ctrl + Home) during the startup.

3. The computer will automatically begin recovering the BIOS. During this time you will see a screen indicating that flash recovery has started.
After the update session completes, the computer automatically restarts.

4. Remove the BIOS flash diskette from the diskette drive.
