Hot Swapping the Battery Pack (Optional)
“Hot swapping” means you can safely replace the battery pack without
shutting down while your computer is running on battery power. This can be
done if your computer has another battery power source.
In addition to the main battery pack, select models have extra(s) which can
be one of the below configurations:
Bridge battery (internal component, not user accessible)
Second battery pack (
occupying the multi-purpose bay, user
accessible)
Bridge battery and second battery pack
Hints and Reminders
See “Replacing the Battery Pack” for replacement instructions and note the
following hints and reminders on hot swapping:
Make sure the battery pack to be installed is charged.
The appropriate temperature range for hot swapping the battery pack is
between -21
°
C (-5.8
°
F) and 55
°
C (131
°
F).
Check the Battery Hot Swapping Indicator after removing a battery pack.
Replace the battery pack only when the indicator lights in green. A red
light means there is not enough extra power for you to safely hot swap
the battery pack.
Once a battery pack is removed, the display brightness level will be fixed
at a low level and cannot be adjusted.
If a charged battery pack is not inserted within 2 minutes, the Battery
Hot Swapping Indicator blinks in red and the computer enters
Hibernation mode.
