128 Mobile Computing Charging batteries 4 Connect the AC adapter to the computer and the power cable to a power outlet. The DC-IN (if applicable to your system) or AC power light should glow green, and the battery light should glow amber to indicate that the battery is being charged. If the DC-IN or AC power light indicator does not glow, power is not being supplied. Check the connections to the AC adapter and power cable. 5 Charge the battery until the battery light glows green. ❖ If you have extra batteries, rotate their use. ❖ If you will not be using the system for an extended period (more than one month) remove the battery. ❖ Disconnect the AC adapter when the battery is fully charged. Overcharging makes the battery hot and shortens its life. ❖ If you are not going to use the computer for more than eight hours, disconnect the AC adapter. ❖ Store spare batteries in a cool dry place out of direct sunlight. Charging batteries The main battery needs to be charged before you can use it to power the computer. You can charge the battery using your computer, or you can use an optional battery charger. CAUTION: Never leave batteries in the battery charger for more than a week at a time. Doing so may reduce the potential charge of the battery. Use only battery chargers designed to work with your notebook computer. You can order a Toshiba battery charger from Toshiba's Web site at toshiba.com.
