Mouse pad stalls and i see a little red light on the mouse pad....i have a compaq laptop but not sure what version...how do i disable thi feature so i dont have to use a physical mouse

The little red light is likely from the red LED underneath your optical mouse. If the mouse cursor/pointer on the screen is jerky, it may mean the mouse pad is dirty and/or if the mouse is wireless, its battery is low and should be replaced. Most laptops have a touchpad as part of the keyboard. If you want to use that instead of a physical mouse, just put the physical mouse away and use the touchpad. Both should be active unless the touchpad was disabled. If the touchpad is disabled, you can re-enable it by clicking on control panel > mouse > device settings tab > enable button.
