Go to Control Panel - Power Options, then set the power scheme on "Always On", then apply the change, then restart the laptop.
Doing that should keep the processor running at its rated speed instead of dropping to a slower speed and making the laptop run like a turtle.
It's my guess the processor is dropping to a slower speed to conserve battery power when you unplug the power cord.
I'm guessing that laptop is over 3 years old.
The battery doesn't last and hold a charge forever.
