I turn on my laptop, sign in (Linux getty), and use the laptop for a couple minutes (no graphical applications), then the screen goes black and the machine does not appear to respond to any user input (CTRL+ALT+F2, etc.). The only recovery I have found is to hold the power button and restart. The logs show nothing. When I use the computer without the power supply plugged in, the problem doesn't manifest. I'm using a Dell Precision M 4700.
Any suggestions? What should I be looking at to begin diagnosing the problem?
Can you try blindly typing a command, like `poweroff`, when this happens - to see whether the device indeed powers off? This would confirm whether user input is still being taken or not, which helps debugging this substantially. -- Rob (coderobe) O< ascii ribbon campaign - stop html mail - www.asciiribbon.org
