I've got a Dell Latitude D620 (WinXP) that is very finicky when it comes to Stand By. About half the time, it goes into Stand By with no issue. The other half it just hangs in the "Preparing to go to Stand By" step forever. Every now and again, the "Preparing..." message is interrupted to tell me that my Intel Wireless Driver is causing an issue with entering Stand By. However, I'm going ahead and calling my computer a liar, since I've disabled the wireless and still had it hang. This includes hitting the manual switch on the side as well as using the Device Manager to disable the card.
Additionally, if it does manage to get to Stand By, sometimes it will just shut down (on full battery). I'm not sure if this is at all related, but I thought I'd mention it.
Anybody know how I can get this fixed?
