Taking care of your battery
Maximizing battery life
To maximize the life of your battery pack:
At least once a month, disconnect the computer from a
power source and operate it on battery power until the
battery pack fully discharges. Before doing so, follow the
steps below:
1
Turn off the computer’s power.
2
Disconnect the AC adaptor and turn on the computer’s
power. If it does not turn on, go to step 4.
3
Operate the computer on battery power for five
minutes. If the battery pack has at least five minutes of
operating time, continue operating until the battery
pack is fully discharged. If the battery light LED
flashes or there is some other warning to indicate a low
battery, go to step 4.
4
Connect the AC adaptor to the computer and the power
cord to a power outlet. The DC-IN or AC power-light
LED should glow green, and the Battery LED 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 adaptor and power cord.
5
Charge the battery pack until the Battery LED 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 adaptor 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 adaptor.
