Battery pack
It is a good practice to have a spare battery around, especially when you travel.
The NiMH battery, coupled with the power management features of your
computer, supplies you with more power on-the-go.
AC adapter
The compact AC adapter charges your battery pack and supplies power to your
computer. You can order a spare AC adapter so you do not need to carry it from
the office to your home or destination.

The PS/2 Y-bridge cable allows you to simultaneously connect two PS/2 devices,
a mouse and a keyboard, to your computer.
