I am still having this waking up issue with my mba 13... when it sleeps for more than 1/2 - 1 hour... it doesn't seem to wake up... it normally wakes up asking my password on top of the screen... but sometimes it reboots.. today something weird happened..the welcome screen came up asking my password... I entered it and I seen the blue desktop screen, than back to the password box.. I entered my password 3-4 times.. it did the same thing.. I pressed and hold the power button.. turned it off then back on... again my outlook file under windows xp in parallels is corrupt... it started pissing me off... anybody have same/similar problem ? any solutions or workarounds?
