BATTERY AND POWER MANAGEMENT
Battery information
The computer comes with a rechargeable lithium-ion
battery pack, which provides up to 2.5 hours usage for
the AL700, or 1.7 hours usage for the AL720. The
battery pack can be recharged between 300 and 500
times. After this it will last for a noticeably shorter
time between charges. At this point the battery should
be discarded and replaced.
Caution
It is possible that the battery may not be fully charged
after transit, and we therefore recommend that you
charge the battery before using it. For details on charging
the battery, refer to the section later in this chapter.
Used batteries can be hazardous; see the Safety chapter
for information about battery safety and disposal.
Fitting the battery
The battery is housed in a compartment on the
underside of the computer. To fit the battery, refer to
the Quick Start Guide at the beginning of this
manual.
Removing the battery
Make sure the system is switched off and the AC
adapter is disconnected before removing the battery.
To remove the battery, slide the battery lock towards
the back of the computer, then raise one end of the
battery until the unit can be lifted from the
compartment, as shown in the diagram overleaf.
