Connect the AC adapter to the computer and the 
power cord to a power outlet. The DC-IN or AC 
power-light should glow green, and the battery light 
should glow amber to indicate that the battery pack is 
being charged. If the DC-IN or AC power-light 
indicator does not glow, power is not being supplied. 
Check the connections for the AC adapter and power 
cord.

Charge the battery pack until the battery light glows 
green.

If you have extra battery packs, rotate their use.

❖

If you will not be using the system for an extended 
period, more than one month, remove the battery pack.

Disconnect the AC adapter when the battery is fully 
charged. Overcharging makes the battery hot and 
shortens life.

❖

If you are not going to use the computer for more than 
eight hours, disconnect the AC adapter.

❖

Store spare battery packs in a cool dry place out of direct 
sunlight.

The life of a battery pack should last for years, depending on 
use. When the battery pack needs replacing, the main battery 
light flashes amber shortly after you have fully recharged the 
battery.
