=[ This just started happening to me!

Reboots about 2-8 minutes in each time, I pulled the battery, still it rebooted (and VERY strangely it reboots back to OS rather than charging mini-OS while plugged in (and yes it's charging according to advanced power applet; and yes it's an official charger). Same issue in stock Diablo install (internal) and heavily-modified install (external)

*grumble* It really shoulda been designed to be dependent on battery while charging. *grumble*

Also I fully charged it last night, then I turned it on today while waiting in line, played Hex-a-hop for a few minutes and then locked the screen as I was called. 2 hours later I tried to unlock the screen then realized it had shut-off. =[

Old batteries, boo!

EDIT: it reboots even in "off"/charging mode!!!
