Battery Pack Maintenance
When operating the UltraBookIIi from battery power,
pay particular attention to:
1. Low battery warning —When the battery
reaches the end of its charge, a “battery
low” message appears, a beeping alarm
sounds, and a PowerTool window appears if
CDE or OpenWindows is running. These in-
dications mean you have approximately
15 minutes to complete your work before
the battery charge is exhausted.
2. When this occurs, follow the proper proce-
dure to shut down the UltraBookIIi quickly
and safely, or connect the AC adapter to
maintain system operation. The Ultra-
BookIIi will continue to remind you about
the low battery status if you continue to use
battery power.
Refer to Chapter 3, Shutting UltraBookIIi Down, for
more information on shutting down the UltraBookIIi.
•
Swapping battery packs—One way to
obtain maximum use out of the
UltraBookIIi's portability is to pre-charge
one or more rechargeable battery packs
before operating the workstation from
battery power. For example, you may
purchase additional battery packs, charge
them, and carry them with you into the
field. As each battery pack becomes
discharged, bring the UltraBookIIi to a halt,
then remove the discharged pack and
replace it with one that is fully charged.
If you shut down the UltraBookIIi to swap
batteries, you must follow proper shutdown
procedures; otherwise, important system files
may be corrupted.
