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.

❖ 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.

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.

battery.
