Juniper Allegro CE Owner's Manual page 41

When the Battery Voltage Drops
As the battery charge drops to 10%, the voltage begins to drop off
rapidly. The Allegro detects this low battery condition. When the
battery indicator begins to flash on and off this lets you know it is
time to recharge or replace the batteries.
When the battery pack voltage drops sufficiently, the Allegro
automatically goes into suspend mode. Charge or replace the batteries
as soon as possible. The battery pack has enough charge left to retain
the system RAM for five minutes, at which point the Allegro
completely powers down to prevent damage to the batteries. If this
happens, the Allegro resets after you charge or replace the batteries.
Any data that were not saved to disk are lost.
Lost Data if Batteries are Removed
If the batteries are removed from the Allegro for longer than five
minutes, the Allegro resets to the Desktop instead of resuming to the
screen that was last displayed before the batteries were removed. All
data that was stored in RAM are lost.
Power Management Feature
To conserve power, the Allegro has an Auto Suspend feature. When
the Allegro is on, it turns itself off if there is no activity after a
specified period of time. This feature is on by default and is set at
three minutes when the Alegro is using battery power or always on
when the Allegro is connected to the an external power supply. The
Auto Suspend is controlled through the Start|Control Panel|Power
menu.
Changing NiMH Battery Pack
The battery compartment is accessed through a door in the back of the
case. Before you remove an existing battery pack from the Allegro,
complete the following:
1) Exit from all open programs.
2) Turn the Allegro off.
3) Push up on the sliding latches on the sides of the Allegro to open
the battery compartment door.
4) Slide the battery pack towards the left side of the battery
compartment and pull it out.
