After coming out of hibernation, the login screen on my XP laptop stays on, even though I have it set to turn off the display after 10 minutes, and to go into Screen Saver after 11 minutes, if the turn off option doesn't work. After logging in, the display turns off normally. This just started within the last month or so. It used to work ok. Maybe an update did something wrong. Is there a fix for this?
4/8/13: I edited this to remove "power down" and "restart" from this question. Things work ok for those. The problem only happens after hibernation.
