Thanks all, replying to several comments... > Bad power supply? Flaky power jack?
I don't think this is it -- firstly, I have the battery plugged in -- it has also happened when plugged into two different power supplies. But if you meant an internal power, then that's different. > I saw this on a T410 caused by a bad stick of RAM. I could try removing the RAM (though I've had the same RAM in this laptop for about a year). Trouble is, it only seems to happen every 10 days or so. > faulty CPU fan I haven't noticed the fan not running -- but could it be that the fan is running, but not communicating that to the laptop? If it shuts down for that reason, would it record something in the Event Viewer? > browse the logs under "event viewer" Thanks, I looked there, and I do see several recent "Critical > Kernel-Power" events -- but they seem to say "The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly" -- which leads me to believe these events are just telling me that I crashed, rather than what happened? Thanks again to all -- it looks like this has happened 6 times in the last 2 months, and never before. -Scott _______________________________________________ Thinkpad mailing list [email protected] http://stderr.org/cgi-bin/mailman/listinfo/thinkpad
