My battery in my laptop will not charge it always says 0% and charging then it will say 100% charged and if I pull the A/C power it goes blank like it has no power. The battery is a Lithium-ion.

Computer works fine on A/C power

I called HP and they want like over $150 for a battery.

Somone suggested I update the drivers for the battery and power system

Any other suggestions before I buy a battery?

I have always cycled this battery aleast 1 time every two weeks, I would not think a lithium-ion battery would just croak out of the blue like a Ni-cad
