Hi SMDFlea,
i tried flashing using the attached file, but the screen remains black with no Lenovo logo.
On the first power-up, the fans ramped up to maximum speed for a few seconds, then the system rebooted-still with the same issue.

Update
4 hours later and without battery, the pc turned on.
After a couple of boots it went back to black screen again.
Pls help me
