I have the setting to have it sleep never but today after I was gone for a couple hours and come back it was seeping with the indicator light fading in and out but I could not wake it no matter what I did. I plugged and unplugged the power adapter numerous times, I held the keys to do a force restart and it made no difference at all. I finally had to take the battery out and wait for a few minutes and then begin again. Anyone know why this would happend?? I thought if I check for it to sleep never, that it wouldn't go to sleep at all.
