Using your laptop's touchpad can temporarily disable the keyboard due to an integrated setting that prioritizes touchpad input over keyboard input to prevent accidental key presses while typing. This behavior is often found in laptops with gesture features or specific drivers that manage input devices. Additionally, certain applications may also trigger this functionality to enhance user experience. If this becomes a frequent issue, checking the touchpad settings in the control panel or updating drivers may help.
