IBM MX5 - Manual (Page 26)

removed or has failed. The backup battery requires no user intervention.
Replacement is performed by LXE. LXE recommends an MX5 in storage have a
charged main battery pack installed.
Note: This mobile device's backup battery maintains it’s charge by drawing
power from the main battery pack. Always store unused devices with a
fully charged main battery pack installed. LXE recommends an in-use
mobile device be frequently connected to an external power source to
retain optimum power levels in the main battery pack and the backup
battery. When the backup battery and main battery pack are dead, the
mobile device reverts to setup defaults when a fully charged main
battery pack is installed and the device is powered On again.
Battery Hot-Swapping
Replace the main battery pack after first pressing the power key and placing the
MX5 in Suspend Mode. LXE recommends any work in progress be saved prior to
replacing the main battery pack.
Simply replace the discharged main battery with a fully-charged main battery.
The backup battery will retain data during a main battery hot-swap.
Place the battery in the battery well, making sure the tabs on the bottom of the
battery pack fit into the slots at the bottom end of the battery well. Push the
battery down into the battery well while fastening the screws. Fasten the screws
tight enough to allow the rubber gasket to create a watertight seal. If the screws
do not easily twist into the threaded opening, remove the battery and repeat the
process.
