I recently upgraded my laptop to windows xp pro sp2 and I noticed a problem that I didn't experience before while I was using "home edition".
The problem: when I put my laptop to sleep (i.e: standby), I can't get it to awaken again. When I press any key, my laptop makes a woking noice but the screen stays black. It doesn't matter how long I wait, it just won't come back.
What could this be?
