When I'm using my laptop, why does the battery only charge when it's above 80% but doesn't when its

[l4ourk]

when the battery is below 70% my battery doesn't charge unless my laptop is off and i have to wait till it's above 80% so i can use it 

when i'm using the laptop on battery and gets low and i plug in the charger it only charges for few second then plugs off so i have to turn it off wait till it's charged and use it again 

i can use it for several hours on charger when the battery is charged 

the battery life is about 3-4 hours and i have no other hardware ptoblems 

i haven't try any other charger brick so i'm nit sure wether it's the charger "adapter" or the battery

Hi@l4ourk, Welcome to the HP Support Community!

I understand that you have an HP PAVILION 15 Model 15-Bc011nf and the battery charges 70% and then stops. You've done a remarkable job performing the steps. 

Did any software changes or updates happen on your laptop after which the battery stopped charging at 70%?

While you respond to that, I recommend you to perform the following steps to isolate the issue and arrive at a fix: 

NOTE: You may skip any steps that have been performed by you already.

• Power off the laptop.
• Remove the battery out. If the battery is integrated and does not have a latch to release it then leave the battery inside the laptop.
• Disconnected AC adapter from the laptop.
• Press and hold the power button for 15 seconds.
• Reconnect the battery and plug the AC adapter.
• Power ON the laptop.

Now let us uninstall the battery drivers and reinstall them. The following steps will help:

• Open the device manager. 
• Expand "Batteries". Right click on the ACPI battery drivers and select uninstall. If there are multiple entries of the ACPI battery drivers then uninstall them all.
• Close the device manager. Restart the laptop.
• The Windows operating system will reinstall the battery drivers while restarting. 

It is a good idea to download and run a BIOS update for your laptop via this link. The charger must be connected until the BIOS update is complete to avoid any power interruptions due to the battery draining out. 

Post a successful BIOS update,  you may check if the battery charges fully. If not then please perform the steps as described in detail in this HP document. These steps help in testing and calibrating the battery. 

NOTE: Please skip the steps mentioned in "Test and calibrate the battery using HP Support Assistant".

I sincerely hope this fixes the issue. Keep me posted.
