Nope.  Plus, this is not a normal OS shut-down.  Yesterday, for example, I
was composing an email in Chrome/Gmail and the screen just when black and
within a second the Thinkpad's BIOS splash screen displayed.  As if the
machine was off and I just turned it on to start it up.    Nothing to
indicate it was restarting or halting or anything in the logs I could see.

More commonly, I'm seeing freezes.  Also yesterday I unplugged the power
cord and the machine froze.  I could not change VTs (e.g. ctrl+alt+F1).
 Also sometimes happens after waking up from sleeping.  Had to hold down the
power button.

I'm starting to suspect hardware on the laptop, but like I said this all
started with 9.10 upgrade.  I should probably reinstall 9.04 and see if it
goes away.  Not thrilled about having to rebuild all the tools I need for
work on this laptop, but a fresh install is always a nice way to clean out
the crud.
