I experience the same thing; sometimes- not every time - (and I can't work out what the common factor is) - when I try to resume from hibernate, Vista goes to the log-in screen (for my password) briefly, but then proceeds to shut down. I say 'shut down'; it actually proceeds to hibernate again. Sometimes I've had to attempt to wake it up 2 or 3 times before it finally sticks on the log in screen and enables me to log in. It really is very frustrating and can't find anything else on the web about this - surely it's a more common issue?! -- JCT38 Posted via http://www.vistaheads.com
