电源键失灵怎么办

If the power button on your device is not working, you can try the following steps:

1. Check if the power button is physically stuck or damaged. If so, you may need to get it repaired or replaced by a professional.

2. Try using a different power source or power cable to see if the issue is with the power supply.

3. If possible, try performing a hard reset on the device by removing the battery (if applicable) and holding down the power button for 30 seconds. Then reinsert the battery and try turning on the device again.

4. If the above steps do not work, it is recommended to contact the manufacturer or a certified technician for further assistance.
