Windows 10: Laptop immediately shuts down when I disconnect it from charger

I have a HP laptop 15s-eq2xxx of 8GB RAM and 496 GB storage. It has a 64 bit operating system and a processor, AMD Ryzen 5 5500U with radeon graphics. Using windows 11.About a month ago, my laptop's original charger of 45W broke and I got a 65W charger to charge it. It never charged the laptop to 100 then and heated the right side of the keyboard. After about some time, the charge rate seemed the same like it would stop charging at 60% after many times then it gradually got low like about 31%. The charging port's light turns white after only 31%. So about a week ago, something happened which

G751JY AC charger disconnects while gaming.

So a few months ago my battery died, which in turn made my computer turn off while gaming. It seemed that the computer (GPU?) needed more power than the AC could give causing it to shut down.

So I got a new battery, and everything worked fine for a week or two. Now when I play demanding games like PUBG the AC charger disconnects and reconnects frequently, and sometimes the computer shuts down. GPU-Z logs say that the temperature is not above 80' degrees just before the shut downs, which leads me to believe its a problem with energy consumption.

The computer is an ASUS ROG G751JY with Nvidia 980m. The AC part is original, and the seller said the battery is original too (and it looks identical to the original).

Other things to note is that during gaming the right side of the laptop is significantly warmer than the left side. The right side is where the AC intake is. The AC jack (?) is also pretty warm when gaming.

Again the disconnections and shut-downs only happens during demanding games. Never during browsing. Stress tests with FurMark will sometimes shut my computer off immediately, other times just disconnects and reconnects of the AC charger.

I am attaching some photos from a gaming session, with information form HWiNFO64 and GPU-z. The last picture is taken just as the charger disconnects and reconnects.

If I understand correctly my AC charger has 220 watt (19,5 V x 11,8 A), so I don't understand why its disconnecting. I thought maybe I could try to undervolt the GPU, but I dint find a program that could do it. The volt option in Afterburner is already at minimum it seems. I can only overvolt?

Computer Shutting Down After Disconnecting From Charger

Hi Matt,

Conflicts with the power plan settings is one of the possible reasons why your laptop is shutting down once the charger is removed. A power plan is a collection of hardware and system settings that manages how your computer uses power. Resetting the power plan
to default sometimes resolve the issue. To reset power plan to defaults, kindly follow the steps below:

• Press the Windows key, and type command
  prompt, and press Enter.
• Copy and paste the command below into the command prompt, and press Enter.
  
  powercfg -restoredefaultschemes.
  
• When finished, you can close the command prompt.

Should you need further assistance, don't hesitate to get back to us.

 

My laptop shuts down as soon as I unplug my charger.

My laptop shuts down as soon as I unplug my charger.

I tried the below method of troubleshooting:

Unplug your Laptop and remove the battery

Press and hold the Power button for 30 seconds

Plug your laptop back in and replace the Battery

Start your PC.

When I perform the above steps and then remove the charger, the laptop works fine on battery.

However, when I plug in in again and then remove the charger it shuts down again.

And I have to repeat the procedure again to use it on battery.

How can I permanently fix this issue?
