Battery problems

[irejn]

Within the last two weeks, the state of my battery has degraded rapidly. While I understand I probably need a battery replacement I would like help in finding out what may have caused the issue. I did battery performance check via powershell and expected to see a change in performance and full charge capacity (since I have had the laptop for about 2 years). However, the kind of problems that are currently occurring seem unnatural. The battery level "jumps", if not plugged in, it will jump from 77% to 45% within 5 minutes. Once plugged in, it will be fully charged in 10 minutes despite having been at 17%. These issues only started occuring now and I have not changed anything in terms of usage. 

Another problem I have is that the fans keep going into overdrive (very loud) when I am not doing much on the laptop. I am assuming this mainly due to dust build up. Is there a way I can prevent this build up because cleaning it regularly is difficult considering my laptops build.

Hi@irejn,

Welcome to the HP Support Community!

I understand that you have a HP Pavilion Gaming 15-Dk and the battery charges issue 

Did any software changes or updates happen on your laptop?

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 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.
