5.2 Replacing Hot Swappable Battery (For M101B)
The tablet computer supports hot-swapping of batteries, meaning the tablet doesn’t need to be
powered off in order to replace the main battery. To support such mechanism, there is a backup
battery inside the tablet that is charged up with the main battery. This backup battery cannot be
removed, and needs to have adequate power for hot swapping of main battery to be done without
issue. When the backup battery is fully charged, it can sustain up to 5 minutes of runtime to allow
for battery hot-swapping.
Perform the following to hot swap the batteries:
1. While the tablet is powered on, go to Hottab utility to check on the power level of the
Backup battery.
2. If the Backup battery level is at “Low”, please charge the tablet with AC Power until the
Backup battery level is at “Medium” or “High”, and do not remove the main battery.
3. If the Backup battery level is at “Medium” or “High”, continue to remove the main battery.
4. Insert a new charged up removable battery into the battery compartment.
5. Go to Hottab utility to check if Main battery level can be correctly read. If not, check if the
new removable battery is inserted properly.
6. If Main battery level can be read, continue to use the tablet computer.
To keep battery health and prevent possible issues from battery
over-discharged, please charge the tablet built-in back-up
battery once for every 2 months.
