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.
