Laptop mouse query

"I connected a mouse to my laptop but now when I take it out the touchpad will not work."

Depending on the type of mouse you may need to restart the laptop in order to restore functionality to the touchpad. If you plug in a USB (flat connector) mouse after the laptop is booted you should be able to disconnect the mouse and immediately begin using the touchpad however if the mouse is a PS2 mouse (circular connector) it is recognised at boot time as the primary input and as such cannot be easily switched without a second boot-up. If you are having this trouble with a USB mouse i suggest you contact the manufacturer of the laptop  as they ill be able to troubleshoot further.
