Toshiba A45 Series manual 129, 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 adapter 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 main battery light flashes or there is some other warning to indicate a low battery, go to step 4.

4 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 main 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.

5 Charge the battery pack until the main 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.
