The battery is easy to find. It's one of those flat circular batteries.
It might have some kind of colored tape around it. here are some examples.






You access it by removing the back cover.
There 3 main ways laptops are designed for giving you access to the motherboard.
  1. If it's a good design, you can screw off some sections on the back. That should be enough for you to work on it.
  2. Taking off the hole back cover. Remove all the screws and slowly take off the cover by one of the corners and go along the sides. It will be held in place by plastic hocks.
  3. In some annoying cases (might be in your case, i have seen a couple of Samsung laptops have this) you actually have to take off the keyboard first. Below that you will see screws that loosens up the back cover. After that it's just like the second case (loosen the hocks slowly). Note: There might still be some screws on the back. Don't understand why some companies does this. What's the point of having screws under the keyboard then,

You will have to find a 2pin connector on the motherboard.
And ether make or buy the example 1 of the above pictures

It could be wired in like this, in which case, it'll be a bit more awkward to replace! I've seen this on IBMs before, but the pic below is what I found when trying to find a picture of the motherboard for you!

It doesn't look like it's worth spending any money on it, if you can pick a piece up for maybe a fiver then it's worth doing.

I finally caught up with the users manual. The manual itself is dated 6 Sept 2005.
I have to agree with Joe. Unless you're in to antiques, it's not worth fooling with.
