Laptop Performance drops when A/C unplugged

Most laptops have features that throttle down both the GPU and the CPU when you run on battery in order to save power. For the CPU, the feature is called speedstep for Intel CPUs. You have to go into the BIOS to disable this feature. For your GPU since it's a NVidia card, you'd most likely have to go into the NV control panel and either look for power settings or a section called PowerMizer.

Note: your battery life will drop like a rock since both the CPU and GPU will run full tilt.

Theres not much i can do in this bios, change the date and time really. Boot menu. Not a whole lot.

But i did happen to download CPU Z again, just to see what changes when i unplug the A/C.
Its not the CPU
Its the GPU the shaders the memory and core both cut in half.

No i went into NVidia cntrl panel and i found "Power Management mode" it was set on "Adaptive" And i set it to "Prefer Maximum Performance.
But still hasn't changed anything.
