Replacing Hot Swappable Battery
The tablet computer supports hot-swapping of batteries, meaning the tablet doesn’t need to be powered off in order
to replace the mainbattery. 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.
