Hi@As82,

Welcome to the HP Support Community! I'd like to help!

I see you are experiencing issues with the Battery on the HP Laptop PC.

I have a few recommendations 

• Make sure the Windows and HP support assistant updates are up to date. 
• Update your Notebook computer to latest BIOS F.36 from HP.COM.
• For Testing and Calibrating the Battery please click this link

Try changing the power mode to "Balanced" or "Better Performance" as the default setting.

Go to "Control Panel\Hardware and Sound\Power Options" > "Change plan settings" > "Change advanced power settings"
Scroll down, click on "Dynamic Platform and Thermal Framework Setting" > "Config TDP Level",
Then select the middle value for both "On Battery" and "Plugged In".
Scroll further down. Select "Processor power management";
Then select "Maximum processor state";
Change the value from 100% to 96% for both "On Battery" and "Plugged In" options.

Hope this helps! Keep me posted.
