Low Battery Indicator
When the battery’s power is getting low, and you have
approximately 8 to 12 minutes of power left, the low battery
light starts to flash. Immediately before the battery runs out, the
computer starts beeping. At this point you have only
approximately 1 to 3 minutes to save your data. If the battery
runs out suddenly, you will lose any data you have not saved.
If you are close to a power source, connect the AC adapter to
avoid an interruption in your work.
If you don’t have your AC adapter with you, follow these steps:
1. Complete your current activity as quickly as possible.
2. Save your data.
3. Exit the program you are using.
4. Turn off the computer.
5.
If you have a spare charged battery, you can install it now.
See “Replacing the Battery” on page 4-2.
Caution
Make sure you turn off the computer before replacing a
battery. Removing the battery when the computer is
turned on causes the computer to restart, and any data
not saved to disk is lost.
If you do not have another battery, you need to wait
until you have the AC adapter to continue using your
computer. Then see “Recharging the Battery” on page 4-4.
