What to do if the Xiaomi Cordless Hair Straightener Brush cannot be turned on by pressing and holding the power button?
If your Xiaomi Cordless Hair Straightener Brush fails to turn on after pressing and holding the power button, the first thing you should do is check the Travel Lock button, which is located on the side of the device. The Travel Lock is a safety feature designed to prevent the brush from being accidentally activated during storage or travel. To resolve this, ensure that the Travel Lock button is in the "unlocked" position. If the Travel Lock is engaged, the device will not power on. Once you have confirmed that the Travel Lock is disengaged, you can press and hold the power button for about 2 seconds to turn the device on. This feature is particularly helpful for preventing any unintentional activation when the device is being stored or carried.
