black screen after bios upgrade lenovo

Post by vst » Tue May 15, 2012 9:54 am

I upgraded a thinkpad t500 bios. After the successful upgrade process the machine wouldn't boot up again.
After some research and patient I found that it boot normally but with half an hour delay.
It appears that the Intel AMT Chip had an old firmware what is not working properly with the new BIOS version.

Once the machine was up and running I'v downloaded and installed the latest firmware version from lenovo and all was fine again.
so long and thank you for the fish
