Generally, we hold the power button seconds to turn on your watch. But sometimes your watch may suddenly shut off and the power button may not work anymore.
This may be a hardware damage, if so, that means your device is broken, you can’t use it anymore. But it may be a software issue, here I want to introduce several methods to fix your watch.
First, plug it to a charger for a few minutes.
Most of smartwatch has a battery life issue, the more complete function watch the short battery life. The battery becomes impure after charging every day. If your watch’s battery life is almost dead and you let the battery drain out, the power button won’t respond you anymore. To fix such issue, you just need to plug it to a charger for a few minutes. Don’t turn it on immediately. After a while, you can turn it on and it will work normally. But you’d better charge it when it is power on.
I also heard someone complaining that their watch can not charge anymore. You can change another usb port or change another usb cable and be aware of the metal in the dock, you may probably break the back cover.
Second, disconnect the battery or cut off the power.
Android watch or tethering watch OS is not as Android Wear OS stable, sometimes it maybe hard-freeze and can’t respond.
You can hear the sound, when you press the button, but the screen remains black. This can be caused by your damaged screen, or the frozen watch OS. You can disconnect the battery wait for minutes and then reconnect it again, to do a hard reset. If the battery is not interchangeable, you can press the power button ten seconds to cut off the power. Then you can boot it up.
Third, factory reset and firmware update.
In some cases, your watch do boot up but there may be still some function won’t work, simply you just need to do a factory reset. It will erase the cache then the watch would work smoothly. If your watch can’t even boot up you can download the MTK droid tool to create a back up or recovery. And then use SP_tool to flash the recovery. You can also download the firmware in NO.1 official website, flash the firmware directly.
