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.
