Windows 10: Laptop significantly slows down while charging/plugged in

TL;DR is at the end of the post

Hello everyone.

My current laptop is an HP 15-r218nv. I know this isn't the best laptop for gaming, but it gets the job done. I have bought it 3 years ago and it has worked great throughout all this time. Last year, the laptop began to overheat, and because I didn't have money to get it cleaned, and I wasn't confident enough to open it and clean it myself, I took the battery out, the easiest and most efficient way to lower the heat and not lose much perfomance. I have continued to play games as normal, and about 4 months ago, there was a storm at my place, and the storm fried up the power brick. I have recently been gifted another laptop, and this new laptop's charger could fit and charge my old one, so I decided to factory reset the old one, and update it to windows 10 version 1903 I had windows 10 version 14XX.

Because I have one charger, I must reconnect the battery of the old laptop back. I did that, and downloaded some games again. I have began to play games and I noticed something strange while playing CS:GO. I have been playing CS:GO without the laptop charging, and I have had great fps, around 100 fps. The battery got at a low percentage, and I plugged the charger into the laptop, and immidietly noticed an fps drop to 20 fps, with also, a drop in CPU and GPU usage, from ~80% to ~35%, and ~100% to ~50% respectively.

I have thought that the fps drop was due to the laptop changing some options and settings because of the battery/power plan, so I waited for a few seconds, but the fps did not bounce back. When I noticed the fps weren't going to jump back up, I unplugged the laptop to perform a test and see what the fps outcome would be. My fps jumped right back to 100 fps. The next day, I decided to run CS:GO again, and noticed low fps again. I tried a different method to the problem, to see if it would solve it.

My laptop has an Intel Core i7-5500U and an Nvidia GeForce 820M. I use the integrated graphics, since they are more responsive and faster than the Nvidia GPU.
In the nvidia control panel, I can choose what GPU I want each program to use, and I thought I forgot to switch the preffered GPU for CS:GO to the integrated graphics, but that wasn't the case. I thought the control panel was bugged, so I disabled the Nvidia GPU through device manager. The game was still laggy.

I enabled back the Nvidia GPU, and went on google to find some answers to my problem. The supposed solutions I found were:

1. It might be a BIOS setting. This might be the reason, and I say might, because I cannot see any setting that would be causing this, but my BIOS have a very limited amount of settings that I can change.
2. A power/battery plan option is at fault, which is not
3. Maybe in the control panel of the Intel iGPU, I have things configured wrong, which that is also not the case

None of these solutions worked, and I have no idea what to do next. If anyone has any idea what the problem might be, I would appreciate it if you could help me



TL;DR
My laptop's CPU and GPU usage drop significantly when plugged in, almost getting halved. Changing the BIOS doesn't help, the power/battery plan is correctly configured, and the configuration from the control panel of the graphics are correctly set. No idea what to do next.

My Computer is Plugged in but not Charging

My laptop computer is plugged in but not charging. The power supply will maintain the charge level (%), but not add to it. Removing and reinserting the battery allows the power supply to add to the % charge to 100%.

Steps performed:

• Turning the computer off and restarting it returns the computer to the Plugged in, Not Charging state.
  
• Removing the battery again allows one complete charge, after which the laptop would no longer charge again.
  
• I have used more than one power supply with the same condition.
  

To resolve the issue, I remove the battery, obtain a complete charge, and maintain this charge by always keeping the power supply plugged in.

What is the root of the problem?

 

Plugged in but battery does not charge

If the laptop works without the battery then charger is functioning correctly. Take a cloth with a bit of rubbing alcohol on it (or some on-the-go alcohol swabs), and clean the metal contacts that connect your battery to your laptop.

Make sure to install all Windows important updates.

Install latest versions of your laptop device drivers you can download the latest device drivers from the device manufacturer or from your laptop manufacturer website.

3. Connect the AC power adapter to your laptop.

4. Power on the laptop

5. Open the Device Manager by typing Devmgmt.msc into Start Menu or from Control Panel.

6. Under the Batteries category, right-click all of the Microsoft ACPI Compliant Control Method Battery listings, and select Uninstall (it’s ok if you only have 1).
