That's a common problem after performing a BIOS update. Do what Tesla suggested. Go into your BIOS settings and Turn On the scheduled power on. Just pick any time. Reboot and go back into the BIOS and this time Turn Off the scheduled power on time. That will fix that problem. So what you are trying to do is manually create a scheduled power on cycle in the BIOS, then you are deleting it in the BIOS.
Suddenly my computer turns on by itself every morning. Never did this before. The only change I can think of is that this started happening after BIOS update to 2.3.3, but I cannot be sure that is the cause. I would like to stop this from happening. Greg
