Battery problem

[SigridM]

I have been using my HP laptop for about 4 years now and all of a sudden a fully charged battery only lasts for about one hour. Up until two days ago, a fully charged battery lasted for at least 4 hours. Is this a common problem and what can I do about it? Just get a new battery?

TRY FOLLOWING STEPS:

1.Try  uninstalling the ACPI battery drivers from device manager by following these steps:

Right-Click on start button> click device manager> expand Batteries>then select all the drivers including the ACPI drivers and uninstall it one at a time. Then restart the computer and check again.

2.If first one does not works try updating your BIOS.

3. you can also check that the battery is working fine with hp battery check in hp support assistant.

I also once faced the same issue but later cured it by buying a new battery as the battery check failed.

Some tips to enhance battery life:

• Please always charge the battery to 100% and use it on battery standby.
• Then when the charger is plugged in, there is no issue here. However, when you continue to sue the computer on battery standby, make sure to drain down the battery to lower than 15% before recharging the battery again.
• One in a while, for example, once in 15 days, save up all your work when the battery shows a notification that it is low on charge and allow it to drain down completely before charging again, which enhances the battery’s life and performance.
• This across devices like camera, cell phone or notebook.
• This is because, with each charge and discharge, the battery completes 1 charging cycle and the life cycle of the battery diminishes.
• The battery has a life cycle of a standard amount of charges and discharges only. (depends on the size of the battery)
• It is never a good idea to charge the battery to 100% and deplete 30% of its charge and connect the charger to it again.
• Because you lose out on 70% of its remaining charge and complete only battery charging cycle if you plug the charger back to charge the battery.
• As it goes from 70% to 100% charge and completes 1 charging cycle.
