34 Using a Battery
NOTICE: You must remove all external cables from the computer to avoid possible connector damage.
For information about replacing the second battery, which is located in the media bay, see "Removing
and Installing Media Bay Devices" on page 128.
To remove the battery:
1 If the computer is connected to a docking device (docked), undock it. See the documentation that
came with your docking device for instructions.
2 Ensure that the computer is turned off, in hibernate mode, or connected to AC power.
NOTICE: Removing the battery in while the computer is in standby mode (without AC power) causes the computer
to shut down and may result in loss of data.
3 Slide and hold the battery-bay latch release on the bottom of the computer, and then remove the
battery from the bay.
To replace the battery, follow the removal procedure in reverse order.
Storing a Battery
Remove the battery when you store your computer for an extended period of time. A battery discharges
during prolonged storage. After a long storage period, recharge the battery fully (see "Charging the
Battery" on page 33) before you use it.
