Performance drops when computer gets plugged in.

HP Recommended
HP Pavilion Power Laptop 15-cb0xx
Microsoft Windows 10 (64-bit)



I have this problem where whenever I play any games (Cuisine royal and Cs-Go) my frames drop from 60fps (capped) to between 10-20fps whenever I plug in my laptop. Making it unplayable.


My stats:


Processor:  Intel(R) Core(TM) i7-7700HQ CPU @ 2.80GHz, 2808Mhz, 4 core(s), 8 logical processor(s)

Installed memory (RAM): 16.0GB

System type: 64-bit Operating System, x64-based processor

BIOS Version: Insyde F.19, 12/12/2019

Motherboard ID: 836B

Graphics:  NVIDIA GeForce GTX 1050


I have set all the power settings to maximum performance.


I have updated my graphics card drivers and BIOS to their latest versions.


I have reinstalled windows.


I have a 150W AC adapter.


The temperature of the CPU and GPU don't exceed 75 C so I don't think it is thermal throttling. 


I have noticed that when the PC is plugged in the GPU load is 100%. When I unplug the PC the GPU load drops to 60%, but as I said before it performs significantly better when UNplugged.


Any help would be much appreciated.

Welcome to HP Community


I have gone through your Post and would like to help


Please try these steps


Right-click your desktop background and select NVIDIA Control Panel. You can also find this tool by performing a Start menu (or Start screen) search for NVIDIA Control Panel or by right-clicking the NVIDIA icon in your system tray and selecting Open NVIDIA Control Panel. 


To quickly set a system-wide preference, you could use the Adjust image settings with the preview option. For example, if you have old hardware that struggles to play the games you want to play, you may want to select “Use my preference emphasizing” and move the slider all the way to “Performance.” This trades graphics quality for an increased frame rate. 


By default, the “Use the advanced 3D image settings” option is selected. You can select Manage 3D settings and change advanced settings for all programs on your computer or just for specific games. NVIDIA keeps a database of the optimal settings for various games, but you’re free to tweak individual settings here. Just mouse-over an option for an explanation of what it does. 


If you have a laptop with NVIDIA Optimus technology — that is, both NVIDIA and Intel graphics — this is the same place you can choose which applications will use the NVIDIA hardware and which will use the Intel hardware. 


Keep me posted
