The reasons for the Xiaomi Electric Scooter 4 Pro Max failing to turn on are as follows:
1. The battery enters sleep mode. When the battery level is lower than 20% and has not been powered on or charged for 10 consecutive days, the battery will enter sleep mode. In such a situation, your scooter will not start. Please connect the charger and charge for 3 seconds to activate the battery;
2. The battery is seriously over-discharged or caused by other faults. It is recommended to apply to the local service center for inspection.
