Charging Battery Packs
You can charge one or two battery packs in the computer, in the expansion bases, or in the optional external Battery Fastcharger.
NOTE: Refer to the documentation included with the optional external Battery Fastcharger for information about charging battery packs in that option.
Charging Battery Packs in the Computer
The computer begins charging a battery pack that has less than a full charge whenever an external power source is connected. The yellow battery light on the front of the computer turns on to indicate when a battery pack is charging. When a battery pack completes fast charging, the battery light turns off. The computer charges a battery pack in the battery compartment first and then charges a battery pack in the MultiBay.
Fast charge is a rapid charge to a battery pack in the computer. The time required to fast charge the battery pack depends on whether the computer is off or on and the type and number of features or optional hardware being used. An optional battery fastcharger also fast charges both packs.
Each fully discharged battery pack charges in approximately 1.5 hours when the computer is off. Charging time is increased when the computer is on.
IMPORTANT: After it fully charges a battery pack, the computer (or expansion bases) maintains the charge by supplying a constant trickle charge. Therefore, if you keep battery pack(s) in the computer or expansion base when it is connected to external power, you will extend the operating time of the battery pack(s).
Charging Battery Packs in Expansion Bases
When you dock the computer in one of the expansion bases (which is connected to an electrical outlet), the expansion base begins charging battery pack(s) that are less than fully charged.
