    Well, the laptop is automatically down-clocking the CPU to conserve battery power. Assuming you are not worried about that, here's one way to fix it:

    Go to Control Panel -> Power Options. Set your profile to "Always On". Also, make sure that in the Nvidia control panel you turn PowerMizer off.

    Regards,

    Always On won't do anything - the Power Plan downspeeds the CPU when it's on the battery to begin with. It doesn't make any difference if it's on all the time, as the Processor Power Management setting needs to be changed.

    Control Panel - Power Options - Change Plan Settings - Change Advanced Power Settings

    Once you're in Advanced Settings, go to the Processor Power Management settings. There are 2 settings, Minimum and Maximum. Change your Minimum state.

    Keep in mind by doing this that you'll gain CPU speed on battery, but your battery drain is going to go up a lot. You're better off losing background processes.

    also there is no way to increase the clock speeds of the GPU while on battery, it always downclocks on battery and theres no over-ride.

    There's a battery icon on the lower right corner of your screen by the time. Left click it and choose High Performance.

    If it still lags or game is slow and choppy on battery, try using the nvidia mobile graphics driver 179.28. It could be that you're probably using a modded graphics desktop driver that messed up settings in your laptops registry. The nvidia drivers should fix that, just make sure you chose High performance for current power plan.

    The thing doing this is called PowerMizer, a program thingy made by nVidia to downclock the GPU when it is running off of a battery to make the battery last longer.

    If you, like me, do not like it and enjoy gaming while on battery for short periods of time then you have to disable it via Regedit, the step by step is here
