Hello, all -

My girlfriend's laptop (Gateway ML6720, Hardy installation) is having an intermittent problem I believe is related to power-management. Every so often, overnight, the machine will blank the screen and become totally unresponsive. The caps lock indicator blinks regularly, but Gateway tech support was unable / unwilling to tell me what the blink code indicated. Hibernate has been disabled (computer and display never go to sleep when inactive), and the power button is configured to ask for input instead of a default action.

She claims that she isn't doing anything special on nights when this happens and is simply leaving the computer on a desk.

Anyone have any ideas for what might be causing this, or ideas on where I can look for further information?
