The HP Bluetooth PC Card Mouse combines all the advantages of a wireless optical mouse in a PC card form factor. The innovative design eliminates all the hassles associated with carrying, charging and connecting a standard corded or wireless mouse.Storing neatly inside the PC card slot of your HP Business notebook, it charges automatically (when the notebook is powered on) so there is no need for cumbersome cables or batteries. Bluetooth technology eliminates the need for dongles thereby leaving your USB ports free for other usage.With its sleek design and integrated "kickstand", it provides all the ease of use you would expect from a standard optical mouse. Gently open the kickstand to activate the mouse, and use the low-profile HP Bluetooth PC Card Mouse. Compatible with all HP Business Notebooks with a PC Card (PCMCIA) Slot and embedded Bluetooth wireless technology.
