Re: Motherboard/CMOS/bios backup battery ??
CR2032s are fairly common batteries. They are often used in Cameras or Clocks, so you'll probably find some in your local Boots (or any chemist or camera shop) or your local Jewellers.
Just buy a new one, then use a flat blade screwdriver (or similar) as a lever to pull the old one out of it's socket, then push the new one in, making sure it's facking the right way,
