If you're brave enough, you could DIY it using the guides here: http://www.tim.id.au/blog/tims-laptop-service-manuals/
Hopefully this guy won't charge you too much though, especially on a 10 year old laptop

Ah no, he is very honest and charges less than most people- that's why I go to him.

Yes, it's the old HP laptop that was Microsh*t XP that you helped me Peppermint a few weeks ago- remember that?
Anyway there must have been something wrong with the battery as you suspected, as last night the laptop fell off its cooling mat ( only gently not far to the floor) and its battery fell out! So now I don't have to worry for the time being about trying to take out a battery. It hasn't shut itself off since. I am using it on mains right now and will see the PC man when got time/money.

If it's always going to be plugged in, you don't need to replace the battery at all.

I know, but it will save electricity usage to use the battery!

Actually, using the battery will use more electricity.  My thermodynamics is very rusty but whenever any charging happens some power is lost as heat. 
Mark is right:  if you don't need portability, just dump the battery and use the mains adapter.

As well as charging inefficiency due to some of the current being coveted to heat, batteries are very inefficient at storing power ..You ALWAYS put MUCH more power in than you'll get out.

The batteries don't get charged for free .. the PC will be drawing more current whilst the battery charges.

Also, as a battery ages and looses its ability to hold a charge, the battery may get to the point where it NEVER gets charged enough to switch the charging circuit off .. so your PC will ALWAYS be drawing the charging current on top of what it needs to run.

As Keith says, you'll save power WITHOUT a battery, not with one. ;)

You may even find your power supply runs cooler now, as it's no longer permanently trying to charge a battery that is unable to hold that charge.

Ok, thanks guys- won't bother with a new battery. I won't really be taking it anywhere- got the Dell netbook for that. I have been using this laptop a lot at home- more than I thought I would actually. I am using it for typing stuff up and VLC videos cos it has a much bigger screen than the Dell. My Dell is still my main one though and use that for skype as it has the webcam. I will recycle the battery.

in that case it sounds to me like a hardware issue such as a bad memory chip but it might also be a bad connection at the power jack, with the battery out try gently moving the power plug at the laptop end from side to side to see if it causes the laptop to shut down suddenly
If you can keep your head while all around are losing theirs, then you're not quite grasping the situation

Did it shut down with a message "saying" it was shutting down, or did it just immediately go off (as though you'd pulled the plug ?

No, jiggling it or moving it doesn't do it- the jack fits in nice and tight.

Firstly, the web pages stall then it goes to a black screen with power shutting down message.
