Mobile Computing
Running the computer on battery power
♦ Amber indicates the battery is charging.
♦ Flashing amber indicates that the charge is running low.
To see how much battery power you have left:
HINT: Wait at least 16 seconds after turning on the computer
before trying to monitor the remaining battery power. The
computer needs this time to check the battery's remaining
capacity and perform its calculations.
1 Click Start, then point to Settings, and click Control Panel.
2 Double-click Power Management.
In the Power Meter section of the dialog box, a bar composed
of a series of boxes indicates remaining battery power. The
longer the bar, the more power you have left. You can also
show the remaining power as a percentage.
TECHNICAL NOTE: The computer calculates the remaining
battery charge based on the computer's current rate ofpower
use and other factors such as the age of the battery.
The computer drains the battery power faster at low tempera
tures. Check your remaining charge frequently ifyou're work
ing in temperatures below 50 degrees Fahrenheit.
What to do when you hear a battery alarm
The computer has two alarms designed to give you sufficient
warning before your battery becomes fully discharged.
HINT: If Hibernation is enabled, your computer sounds one
alarm. Instead of a second alarm, your computer automati
cally goes into Hibernation mode.
