Laptop sent in for repair but not fixed.

So recently I sent in my laptop for repair because when charging and playing games, I would have massive FPS drops. They sent it back with a replaced motherboard and updated bios. The problem still occurs, and I wonder if the problem could be my charger?

Do you have the "high performance" plan enabled, both for battery & while plugged in?

Unlikely to be the charger, if it's the stock charger.

For maximum performance you need to play games while plugged in.

You also need to select the discrete graphics adapter and not the integrated adapter.

In the BIOS setup go to the "performance" might be something different on your laptop and disable Intel speed step. Laptops are designed to maximize battery life and they do it by compromising all of the components to save power (performance) including the CPU. This drops performance. Just a thought.

You could try throttle stop and uncheck BD PROCHOT to see if that helps.
