that may be. not sure... I am using a Duo AC adapter to power the machine as thats all I have.

if the machine is frozen solid at a screen, it stays that way. it never seems to "shut down" or do a hard reboot. but it WILL hard lockup. frozen mouse and all

And worth mentioning, that sometimes when it chimes, till chime SUPER loud and distorted for about half of the chime. then it gets real low volume for the last half of the boot chime. but when it does this, it dont boot either, just chimes and black screen.
