\015 I did a clean install of all programs after wiping the drive clean and creating a new partition on the drive. After the machine is idle for a few minutes the screen goes blank (blue color). user hits space bar or moves mouse the screen comes to log in. user logs in and the screen goes back to blue. no other activity. if you touch the power button the computer restarts immediately. The power options are set for 'never' on everything and hibernation is off. I did get the system battery is low prompt at one time but have not seen it in a while.\015
