Hitting the power button a couple of times repeatedly with power disconnected, made my Thinkpad pass POST again. XFS rootfs is corrupted and couldn't be mounted anymore, but xfs_repair -L (discard outstanding journal) fixed it.

Now the machine is back to business again.

Motherboard is still a suspect, but It really seemed to be just some conductive metal debris in the keyboard, need to wait and see.

My Thinkpad suddenly died. The symptom is strange - It behaves as if the power button is shorted, it first started when a "poweroff" prompt appeared on the screen, and the machine lost power after 5 secs. After that, the power button isn't as responsive as usual, a hard press is needed to power it back on, and it always lost power after 5 secs.

I've seen enough broken Thinkpad and I don't believe it's how the power supply protection works - i don't think it can inject power key presses, does it? Anyway, I really hope it is just a defective keyboard...
