Laptop battery not charging

[etones]

hey all, hmmm im wondering if anyone could help me, my laptop battery isnt charging, the only way i can use my laptop is if I have it plugged into the mains which is quite annoying seen as its a laptop and I want to use it outside of the house, im not sure whats wrong the charging light comes on and flashes but does not charge.

If it's an old battery then it probably needs replacing, they don't last all that long!!!!
