Hello, it seems to me that my thinkpad P50's BIOS is corrupted. I tried to boot it up and the power button would only blink 3 times green. The serial number is missing from the bottom of the chassis so I'm not sure what to do. I hope it's not the motherboard that's broken......

Hi, I'm requesting the bios for my P50. I messed up badly after an Ubuntu Studio install/update and now when I hit the power button it just flashes the keyboard lights briefly, and does nothing else. No post, fans or screen. I searched the forum and found other firmware posted, but I'm not sure they're compatible. Thanks for any help!

Hi all, I'm Marty and I've joined the forum to request the firmware for my Thinkpad P50.

Update:

This method works with Thinkpad P50 - MEC 1653L. The issue I had before is caused by the resistors (R488, R489, R490, R491) did not populate, so I have been shorting the wrong side.
Do it on the other side works.
