@Fassou said in hp Pavilion bw0xx - Battery:

I agree with @Namiga, that the symptoms you mention point more to a problem in the laptop's power system, than to a battery failure.

If the charger is faulty, it won't work when connected or charge the battery, but I fear the problem will be in the circuit that manages that.

Salu2!

It is clear that this type of problem always comes from the same side.
