CHAPTER 3
Battery and Power Management
This chapter explains how to manage the computer’s power effectively and use the
standard battery or an optional battery pack.
Standard Battery Pack
When not connected to an external power source, your computer operates with the
rechargeable standard battery pack. The duration of the battery life may be longer if
the computer’s Power Management is active. See the next section for power
management.
To keep the battery life long:
•
Initialize the battery pack if the actual remaining power in your battery is less than
what the battery indicator lights suggest as per the procedure on page 3-3.
•
Turn off your computer when you are not using it.
•
The duration a battery charge will last will depend on the computer
usage. Applications which heavily use the peripherals will experience
shorter power duration.
•
When the battery is not charged, your computer may not operate
properly. Connect the AC power to charge the battery.
•
If you see an error message during booting, press F2 to open the Setup
Utility. Following the instructions in Chapter 8, adjust the Setup Utility
and restart the system.
•
When using the computer for several hours with battery packs, enable
power management and set
System standby
. Refer to the
Power
Management
section in this chapter.
