Rugged Windows Tablet M101P
5.2 Replacing Battery
The M101P Tablet supports hot-swap, meaning the tablet doesn’t need to be powered off to replace the
main battery. To support hotswap, there is a backup battery inside the tablet that is charged together with
the main battery. This battery cannot be removed, and requires adequate power for main battery hot
swapping. When the backup battery is fully charged, the tablet can sustain up to 5 minutes of runtime for
battery hot-swapping.
Perform the following to hot swap the batteries:
1. Power on the tablet, open Hottab to check the power level of the Backup battery.
2. If the Backup battery level is “Low”, please charge the tablet with AC Power until the Backup battery
level is “Medium” or “High”, and do not remove the main battery.
3. If the Backup battery level is at “Medium” or “High”, you can remove the main battery.
4. Insert a new fully charged battery into the battery compartment.
5. Pen Hottab to check Main battery level. If the battery level is displayed incorrect, check if the new
removable battery is inserted properly.
6. If the battery level displayed correct, continue using the tablet.
Caution: Charge the built-in back-up battery every two months to keep battery health
and prevent possible issues from battery over-discharge.
