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.
Allow 1hour to charge it, if did not charge check the input & output of the charger if its properly insert, if not again off your notebook & charge it, always check if it is charging, Note: Charging test try on, off, & unuse it allow to full charge the battery before using..avoid low bat your battery when using.
Hi, the problem is you cant without buying a new battery but what they dont tell you and should tell you is this.
when your using your notebook off the mains you should remove the battery as this keeps it working at its best only use the battery when you need to and after give it a full charge then leave it out whilst you use the notebook on the mains.
leaving the battery in will sap the life out of the battery and you will end up needing a new battery every few months as it just wont hold the charge as it did when new.
let me know if you need further assistance ok

Better you first charge the battery for 16 to 17 hours and recheck the same. If problem persists, change the battery from where you bought it. that battery is faulty. And yes there is no need to install the battery from device manager. Just open the battery compartment and replace the battery with new one.
