Taking care of your battery
What to do when the main battery runs low 
When the main battery runs low you can:
Plug the computer into an external power source and recharge 
the main battery
Place the computer into Hibernation mode and replace the 
main battery with a charged spare (not included with your 
computer)
Save your work and turn off the computer
Conserving battery power 
How long a fully charged battery pack lasts when you are using the 
computer depends on a number of factors, such as:
How the computer is configured
How much you use the internal storage drive or other optional 
devices
Where you are working, since operating time decreases at low 
temperatures
You can also conserve power and extend the operating time of your 
battery by enabling Standby or Hibernation mode, which saves 
power when you turn off the computer and turn it back on again.
Taking care of your battery
The following sections offer tips on how to take care of your battery 
and prolong its life.
Safety precautions
If the battery pack produces an odor, overheats or changes 
color or shape while it is being used or charged, turn off the 
computer’s power immediately and disconnect the power 
cord/cable from the power socket. Carefully remove the battery 
pack from the computer.
Do not try to disassemble a battery pack.
Do not overcharge or reverse charge a battery. Overcharging 
will shorten its life, and reverse charging could damage it.
Avoid touching the metal terminals of the battery with another 
metal object. Short-circuiting the battery can cause it to 
overheat and may cause damage to the battery or the computer.
Do not incinerate a spent battery, as this could cause it to 
explode and release caustic liquid.
If a battery is leaking or damaged, replace it immediately. Use 
protective gloves when handling a damaged battery.
