It was working fine in the morning when I checked email, then shut it off. Later that night when I turned it on, the keyboard backlight came on briefly, which is normal, but then it stopped on the "ThinkPad" screen, and the light in the Fn button stayed on.
No hardware or software changes were made.
I have tries starting it on external power only, and battery only, no difference. Unplugged and left the battery out for awhile, then tried again, no help.
When holding F2 during power on, it stops on the "ThinkPad" screen, and "Entering Startup" is also displayed,but nothing else happens.
When holding Enter and F8 during power on, it beeps once then stops at "ThinkPad" and "Launching the Startup Interrupt Menu".
I have searched the forum, but have not found an answer to why it is doing this, or how to fix it.
Any ideas wold be appreciated.
If you haven't already I would disconnect all USB connections then try again.

1. Try opening up computer to take out and re-seat all your RAM modules?
2. Take out your HDD/SSD and re-seat all of them.
3. ***How do we know that it is a motherboard failure, and not a HDD/SSD failure?
