How do I change the CMOS-battery? Can't get it loose!

Hi,

My CMOS-battery seems to be dead, since the BIOS resets everytime the power is turned off.
However I have a problem replacing the old battery with a new one, since I can't seem to figure out how to remove the old one! I have uploaded some pictures here. If anyone has any tips, please tell me

I had the same problem and then I read somewhere to do this:

Pull the 2 little silver tabs to the side a little bit and use a jewelers screw driver underneath it and pop the battery out with force. Mine went flying so be careful, but this is actually how you get it out.

Edit:

Also, pay attention to which side the positive side is on before removing.

Thanks for the tip, I will try that when I get home!
