No battery detected


LOL, good ole Vista. I would never discharge my battery once I got it charged. I know the instructions say that, but I just never do it. Sounds like your battery is defective. Send it back.

I have a dv6500 and it work only whit te battery. the ac adapter dont charg the battery and the pc dont work and the charger its ok. maybe a fuse?? tks rgds


If thelaptop battery is more than 3 - 4 years old then the battery could be worn out.Rechargeable batteries have a finite number of charge and discharge cycles andwill lose their charge capacity over time, i.e. won't charge to 100% andgradually the charge reduces until the battery won't charge up at all. OR Thebattery shows a 100% charge but when the adapter is disconnected the batterydrops off to zero capacity in a very short time. If the battery drops to anunacceptable charge level then the battery needs to be replaced.
