Replacing the battery pack
When the battery pack reaches the end of its operating life you will need to
install a new one. If the Battery indicator or Slim Select Bay indicator (if a
Slim Select Bay 2nd battery pack is installed) flashes orange shortly after
fully recharging the battery, the battery pack needs to be replaced.
You might also replace a discharged battery pack with a charged spare
when you are operating your computer away from an AC power source.
This section explains how to remove and install the battery pack.
Removing the battery pack
To replace a discharged battery pack, follow the steps below.
1. Save your work.
2. Turn the computer’s power off. Make sure the Power indicator is off.
3. Remove all cables connected to the computer.
4. Close the LCD display panel and turn the computer upside down.
5. Slide the battery safety lock towards the release (
) position to make
the battery release latch movable.
Releasing the battery pack (1)
■ Do not remove the battery pack while the computer is in Standby mode.
Data is stored in RAM, so if the computer loses power it will be lost.
■ In Hibernation mode, data will be lost if you remove the battery pack or
disconnect the AC adaptor before the save is completed. Wait for the
HDD indicator to go out.
■ Do not touch the battery release latch while holding the computer. Or
you may get injured by the dropped battery pack by unintentional
release of the battery release latch.
