This maintains the system clock and bios chip. Some bios chips contain a built-in 'battery' but this is not replaceble. The best thing you can do is to check the documentation which came with your computer. There may be a motherboard description provided if it was a decent company. Or, discover the make and model of your motherboard, which may be specified in your computer's documentation or you can search for the printed info on the board itself, then look it up on the maker's web site. This will tell you what type of battery you have, where on the board it is, and how to change it. As a last resort you could get a torch and have a good look around. Make sure the machine is unplugged from the mains. ADVICE: It's up to you to accept this or not, but you may cause damage if you don't. Should you find a replaceble battery on the motherboard (and there's no guarantee that you will) then - a) use an anti-static wrist strap clipped to the computer's frame ALL the time that you are working. This is to protect the other components from static electricity damage which may shorten their lives or even destroy them. Some people mistakenly think that just 'touching the frame' before staring work is adequate - IT ISN'T good enough, you must be earthed continuously. b) do not touch the surfaces of the new battery with your fingers whilst putting it in (use plastic tweezers or rubber gloves). This is because skin oils damage the connecting surfaces and shorten the cell's life. There is usually a lithium-ion battery on the motherboard. This maintains the system clock and bios chip.

There is a flat circular battery on the board. Fairly easy to get at. That is, provided you aren't on a lap top. That's even easier. xxR Open the case up.
