My Lenovo T61p has started shutting down randomly (usually in the

of the night). There is nothing in the logs, and the temperatures have

find out whats shutting the system down?
Its always possible that its hardware I suppose... but it always works
perfectly when I'm using it.

Check to make sure you're not getting a bad battery charge level
signal. I was having a similar problem with my desktop computer with a
USB based UPS. It had a bad battery for a while and when I changed it
out for a good one, the charge levels are all over the place which at
some point during the night would go low enough to cause a shutdown.
