Batteries
The power consumption of the Allegro is very effi cient. The Auto
Suspend and Power Management features help to conserve power.
Maintaining the battery pack and backup supply is simple.
There are three types of batteries and a backup capacitor associated
with the Allegro:
NiMH battery pack
Battery holder for three alkaline cells (optional accessory)
Internal lithium backup battery (powers the real time clock and
CMOS RAM and keeps the BIOS settings set in the System Setup)
Super capacitor that serves as the RAM backup (maintains the
RAM for 5 - 7 minutes, while you change the battery pack)
Main Power Source
The Allegro is powered by a rechargeable nickel metal hydride
(NiMH) battery pack. The battery compartment is accessed through
a door on the lower part on back of the Allegro case. The NiMH
battery pack is shipped along with the Allegro but is not installed at
the factory.
Installing the Battery Pack for the First Time
Upon receiving the Allegro, you must install and then charge the
battery pack. To do this, complete the following:
Push up the sliding latches on the sides of the Allegro to open the
battery compartment door.
Place the NiMH battery pack in the left side of the battery
compartment, push down, and slide it all the way to the right.
Push the battery door closed until each latch clicks into place.
