My Acer extensa4420-5963 has been acting funky for the last three/four days. Started out my date and time went haywire. Clock kept losing time as soon as laptop was turned off and reverted to battery. Then I could not start laptop by pressing button. After ten, twenty times pushing button it may or may not start. Machine tries to boot but just doesn't seem to get there. Today when I finally did get running after many attempts, not only was the time off but the date reverted to January 2006. If I do get up and running things seem to work fine. Help!

Remove battery for a minute, reinsert battery and allow clock to settle (15 min) now try.
