Anyone know of a likely reason why my laptop often fails to come out of standby? A few weeks ago it wouldn't enter standby, now it won't wake up! I can't see a commonality to when it won't come back. Seems to be random and not obviously dependant on how long it's been asleep, or what programs are running. Nor does closing it or leaving it open seem to affect whether it wakes up. I turned hibernation off but no change.
The cpu seems to wake up most of the time, or at least the fan does, and sometime the indicator light flashes but no screen.
