HP laptop battery problem!!

hi, does anyone know why my battery on my HP laptop doesnt recharge when it is plugged in to the mains?? It says it is 0% and charging but never actually increases. If you unplug the AC adapter it doesnt turn itself off but keeps warning me that it is at 0% and should be plugged in.
The laptop is only about 5 months old so shouldnt really have this sort of problem.

Any ideas are welcome!!

Oh, the model number is HP Pavillion dv4, if that helps??

Cheers for any feedback,

dan

Try removing the battery and re-seating it, it could just be a bad contact.
More likely is that you have killed the battery, by over charging or too much heat.
There is a tiny computer in most modern laptop batteries that also monitors the charge/discharge, there might be a reset button on the battery to clear it's memory.

wow, I like you says,so the beauty of notebook PCs is the portability, making them an essential device with an obivous advantage of mobility over desktop computers. Of course, after several hours, you will need to recharge your laptop's battery, plugging an AC charger from the mains into your laptop, which means, for a short period of time, it's fixed to one place, making it effectively a desktop PC for a short while.

Try removing the battery and reinstalled, it was just a bad contact.
It 's more likely that you've killed the battery or extreme heat.
There is a small computer in most modern laptop batteries, which also controls the charge / discharge can eliminate a reset button on the battery for the memory.
