computer would not restart (bad CMOS battery?)

Can you wake it up by tapping the Enter key? Check your Power Options to reset to defaults. I like to try mine to see if they work by setting sleep to 1 minute and Hibernate to 2 minutes. Try waking from sleep first, then let it proceed to Hibernate and see if that works and Resumes correctly. Then set them where you want them and enable Hybrid Sleep to avoid losing data during sleep in a power failure.

The computer was still on (fans spinning and MB lights are lit). The displays were off. Pressing any button had no effect. The only options I have are S1 and S3. I presently have the BIOS set to S3. I have since reset the BIOS to defaults, changed the options back to where I had them (fans set to 10%, sleep set to S3, USB KB wake from S3).

Everything is working fine now.

Does it sleep and hibernate correctly?
