What does it mean when electrons not swirling?
 

I just wanted to know what does it mean when electorns on the select browser/configuration screen are not swirling there is just one big electron. I noticed this after I removed and then put back the battery from the mother board.

There is a 10% chance that you have immobilised your PS2 by removing the battery. So don't do it again.

You have lost the CMOS settings in system configuration. When you re-specify them esp. date & time, the electrons will whirl.
