Yesterday it has drained...so today i charge it.. from 9 am - 4:30pm. but when i check it..it has 0% charge.. what should i do?
If the
laptop 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 and
will lose their charge capacity over time, i.e. won't charge to 100% and
gradually the charge reduces until the battery won't charge up at all. OR The
battery shows a 100% charge but when the adapter is disconnected the battery
drops off to zero capacity in a very short time. If the battery drops to an
unacceptable charge level then the battery needs to be replaced.
Rechargeable batteries will fail if stored in a discharged
state for long periods.
