In Progress My laptop has better performance when it's power is plugged out

For testing purposes - disconnect D:\ drive, and C:\ is down to 10% free so cleanup that drive with either CCleaner (free version) or Glary Disk Cleaner or the inbuilt cleanmgr command.
Also, check the HP website for an update to your 5 year old BIOS firmware, maybe they have released a fix if this is a known issue.

I cleaned with CCleaner and updated my BIOS, it made a small difference but it's still way off what my performance should be.

On battery power, laptops usually throttle things downwards to save power, so yours is the opposite - when on mains power, it is slower?
Check the power plan profiles in BIOS, maybe someone has been tinkering and has them adjusted wrongly.

I’ve messed around with my power plan a lot, it’s all set to be at max performance when plugged in or plugged out, but I think I’ve figured out what the problem is. My laptop adaptor is messed up and is not supplying the right power which is causing my laptop to heat up and throttle itself, I’ve noticed that my CPU usage caps at a lower amount when plugged in vs plugged out. When it’s plugged out, it reaches 50% on my task manager’s CPU usage graph but when plugged in, it never goes over 30%. I’m going to try using a different charger to see if that’s the problem.

A couple of long shots...

Try these from an elevated command prompt;
  • chkdsk c: /r
  • sfc /scannow
  • dism /online /cleanup-image /restorehealth
  • dism /online /cleanup-image /startcomponentcleanup /resetbase
ShutUp10 by O&O Software can stop a lot of background & telemetry items, see if that helps (download link on the History tab)
