Dell LT System manual Removing External Battery Pack, Checking the Battery Level

Page 42

Removing External Battery Pack

Before removing the external battery pack, turn off the computer or confirm that the standard battery pack has power remaining. If the standard battery pack has no power remaining, connect the computer to AC power; otherwise the computer will be shut down and data may be lost.

Remove the optional battery by pressing the buttons on each end of the battery and sliding the battery off the computer.

Close the cover of the external battery port after the external battery pack is removed.

Checking the Battery Level

You can check the battery level of the external battery pack (in the same way as the standard battery pack) with the battery indicator. Press the button on the right of the indicator. The status of the indicator is the same as that of the standard battery. See Checking the Battery Level under Standard Battery Pack earlier in this chapter.
