Windows 10: Windows 11 very slow 100% CPU when power plugged vs fast when switched to battery Battery...

This is a hp laptop with Windows 11, with an i3 processor 11th gen processor @ 2GHz, 16GB RAM, 512 GB SSD, an year old. The problem is, whenever we work on our battery battery saver mode on the performance is awesome. Whenever we plugin in the power adapter, things drastically slow down. The main reason I see if 100% CPU, clear increase in number of processes, threads, handles. Simply pull the power off, immediately everything get back to high performance back.Some of my observations, actions I tried to take to fix the problem- When we purchased this laptop an year ago, the problem was not

Power and battery

I just had a black screen; all I could see was the mouse arrow. I researched on my other laptop and discovered it's a common problem with Win10. I tried a few recommended things but nothing happened: black screen and mouse.

For some reason I got it into my head to remove the battery and leave the laptop just plugged into the wall. It started normally and some 6 programs I tried so far have worked perfectly. So now I am wondering whether I should have both battery and wall-power at the same time. Should I perhaps remove the battery permanently and just run the machine on power?

Thanks for all advice, opinions, gossip.

I just called a friend and he suggested I run the machine on battery only until the battery is down to, say, 20%, then plug it in again to power until the battery is back to 100%; then unplug it and run on battery only. Ad infinitum. Any opinions on this process? Thanks again.

 

Energy switches to battery when plugged in

Hello, I have a problem with my energy settings on Windows 10. When plugged in, the energy switches to battery; then i take the energy cord off and on, and it starts charging for some time, then it consumes the battery again. There is absolutely no problem
with the cord.

What didn't work are:

• Reinstalling the battery driver,
• Troubleshooting power settings,
• Windows & drivers are up-to-date,
• System maintenance software & antivirus didn't find anything.

Thank you
