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 internal standard battery pack. The duration of the battery life may be
longer if the computer’s power management is active. See the Power Management
section in this chapter for information about power management.
To keep the battery life long:
•
Use the procedure in the Initialize the Battery Pack section in this chapter if the
actual remaining power in your battery is less than what the battery indicator
lights suggest.
•
Turn off your computer when you are not using it.
•
The duration a battery charge will last will depend on the computer
usage. Heavy use the peripherals, like the external floppy disk drive
unit or the optional external CD-ROM drive, will result in 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 7, adjust the
Setup Utility and restart the system.
•
When using the computer for several hours with battery packs, enable
power management and set the suspend-to-disk mode. Refer to the
Power Management section in this chapter and the Power Menu
section in Chapter 7.
