Possible workaround for blank screen after sleep
Authored by: DHB on Jun 21, '06 02:35:02PM

Most of the time, you're computer is fine but the display is asleep. The computer thinks that it is attached to an external monitor. It is completely awake ... just with the screen off. This usually happens when you attach or disconnect USB devices right as you are going to sleep or waking up.

DO NOT reboot the machine: it's not necessary. You only need to put it to sleep. Just closing the lid doesn't always put it to sleep, especially if it is still attached to an external keyboard or mouse. Remember, it is designed to keep running closed in those circumstances.

The most reliable way to put it to sleep (short of memorizing some blind keyboard commands): close the lid, unplug the power supply, and wait a few seconds. It will reliably go to sleep, which you can confirm by watching the power light start to do it's normal "asleep" pulsations. You should also unplug any external keyboards or mice to be sure.
