[SOLVED] Games are Lags When Charger is Plugged In

[ThisBoyAwesome]

I have a laptop and having a Nvidia graphics card 2GB, but now the problem is that whenever I play High Graphics games then I get a problem. and the problem is this as I plugged my charger to laptop, the game starts to lags, and as soon as I unplugged the charger, the game is done right now.
I don't know How to fix it? Is this due to Graphics Card?
Please Guide me how can I fix it.
Thanks

Check your power profiles. They are independent when on battery and on AC power.
