LUBA 2 Will Not Turn On: Safe Recovery Steps
A completely unresponsive LUBA 2 may simply be deeply discharged, but station power, the removable key, or a device fault can produce the same symptom. Start at the dock and avoid opening the mower.

Quick answer
Place LUBA correctly on a powered charging station and watch the station LED. If it still does not respond, reseat the security key and use the manufacturer reset procedure.

Fix it in this order
- Verify the outlet and station
Confirm the adapter is powered and all connectors are secure. A mower cannot recover from deep discharge if the station is not supplying power. - Seat LUBA on the station
Align the contacts and leave it in place. Mammotion advises checking whether the station LED flashes, which indicates charging. - Allow recovery time
A deeply discharged battery may not wake instantly. Leave the mower docked under suitable temperature conditions and recheck the app. - Reseat the security key
If the station remains powered but LUBA does not start, remove and reinstall the key as described by Mammotion. Ensure it is fully seated. - Use the documented reset
If key reseating does not work, follow the reset procedure for the exact LUBA model. Avoid rapid repeated power cycles. - Stop for heat, odor, or damage
Disconnect power only if safe and contact support if the mower or adapter is unusually hot, damaged, swollen, wet inside, or smells abnormal.
What usually causes this?
Deep discharge, loss of station power, poor docking contact, an improperly seated key, software lockup, or battery/electronics failure are possible.
How to verify the fix
The mower should appear in the app, show a rising battery percentage, respond to controls, and remain on after leaving the station.
Do not skip this check: a cleared message is not proof of a repair. Confirm the mower completes the affected action under supervision before restoring unattended schedules.
When to contact support
Provide the serial number, how long it was unused, last known charge, station LED behavior, weather/storage conditions, and a video of the attempted startup.
Stop troubleshooting and contact the manufacturer if you find damaged wiring, swelling, burning odor, water inside electrical parts, or repeated failures after the documented checks.
