Is it my laptop or battery?

Another thing you can try is cleaning out the fan and heatsink... often these will get clogged with dust and the fan has to work a lot harder to cool the cpu.
On my old laptop the fan was on constantly until I cleaned it, now it only turns on when I'm playing games etc.
In some laptops, the fan/heatsink is accessible under a panel on the bottom of the laptop, which can be removed by a couple screws. If it's *not* accessible, don't bother trying to take the it apart to get at it, it's usually more trouble than it's worth. Just blow a can of compressed air into the vents instead.

I can never find any cans of compressed air here in Australia... I've tried using a vaccuum with a match to stop the fan spinning while the vaccuum was sucking the dust out... My brothers laptops vent is all black and blocked but yet it still lasts 3 hours of a 4400mah battery :-/ It's like he blessed it at a temple... I guess Acer Travelmates are really good if you want a strong laptop with long battery life. I mean he dropped it on the road twice and it still works like nothing happened. I dropped my laptop (well not drop) it was in the laptop bag but I forgot to zip it up, and I lifted the bag and bang, my heart hurt. I got an error when I tried to reboot but it worked after the 2nd try...
