After replacement, check to see if the power supply is adequate?

The laptop shutdown during a firmware update.
I tried flashing two different firmware (BIOS and 1mb chip), but the problem persists.
It powers on, but there is no display.

I suspect it might be the MEC firmware, but I can't find the correct version for this model.
