Setting battery alarms
Your computer can be configured to warn you when the battery is running
low. For more information, see "Setting battery alarms" in the electronic
user's guide.
Changing the main battery
When your battery power is running low, you have two options: connect
the computer to an AC power source or install a charged battery.
Removing the battery from the computer
1
Save your work.
2
Turn off the computer via the Start menu or place it in Hibernate
mode according to the instructions in "Using Hibernation" in your
electronic user's guide.
3
Remove all cables connected to the computer.

front side of the computer facing you.
TECHNICAL NOTE: The computer drains the battery faster at low
temperatures. Check your remaining charge frequently if you are working in
temperatures below 50 degrees Fahrenheit.
The computer calculates the remaining battery charge based on your current
rate of power use and other factors such as the age of the battery.
When handling a battery, be careful not to drop it or short-circuit its
terminals. Also, do not drop, hit or otherwise impact the battery. Do not
scratch or break the casing and do not twist or bend the battery.
Do not remove the battery while the computer is in Standby mode. Data in
memory will be lost.
If your battery discharges fully, your information will be lost. Be sure to save
your work often.
