your battery has failed prematurely.   If there's a active warranty on 
it, I would try and get a replacement from the manufacturer.

I've got a Latitude D600 laptop thats almost 5 years old (new in jan 
2005), still has its original Dell 9 cell battery...   While I 
occasionally use it offline, most of the time its plugged in 24/7.   The 
battery still lasts about 90 minutes of average steady usage, maybe 2 
hours of light usage (remote terminal + wifi, for instance).   This is 
significantly down from the 5 hours it lasted when new but still plenty 
usable.

It *is* important with laptops to keep the bottom air vents clear when 
they are powered.    always use the laptop on a hard surface, or if its 
on your lap or whatever, be sure to position it so the vents are clear.  
I also find I have to partially diassemble the laptop once or twice a 
year to clear out the 'dust bunnies' that collect between the fans and 
the heatsink radiators.   left too long, the dust builds up into a 
rectangular piece of 'felt' that completely blocks the airflow.   some 
newer laptops have access panels specifically for the fans, my older 
ones I have to take apart from the top down.
