Low Battery Pack Conditions

Table 2-1 gives details on system conditions for each charge level indicated by the Low-Battery LED.

Table 2-1 Low Battery Pack Conditions

Low-Battery LED	Low Battery Condition

LED off.	Good Battery
	Greater than 15% battery pack charge remaining.*
LED flashing slowly	Low Battery Warning
(1 second on, 1 second	15% to 8% battery pack charge remaining.*
off).

LED flashing quickly	Very Low Battery Warning
(1/2 second on, 1/2	8% or less battery pack charge remaining.*
second off).

LED flashing very slowly	Critically Low Battery
(1 short flash every 4	• If the system is running when the charge drops to the
seconds).	• If the system is running when the charge drops to the
	Critically Low Battery level, the system is forced into
	Suspend mode.
	• If the system is in Suspend mode when the charge drops
	to the Critically Low Battery level, the system remains in
	Suspend mode.
	The system cannot be started or resumed until a charged
	battery pack is installed or external power is connected.

LED off, system not	Discharged Battery
running and will not start.	The battery pack charge is not sufficient to provide power in
	any mode. After the battery pack drops to the discharged
	level, power is supplied to the system by the built-in bridge
	battery. The bridge battery can power the system in Suspend
	mode for about 3 minutes, after which time any data stored in
	memory (suspended data) is lost.
	The system cannot be started or resumed until a charged
	battery pack is installed or external power is connected.

*These are approximate values. The percent of charge remaining indicated by your operating system or power management software may differ.
