How to turn Xiaomi on if the power button doesn’t work: the complete guide

The situation when your favorite smartphone Xiaomi suddenly ceases to respond to the pressing of the power button, can be taken by surprise. The screen goes out, the device goes into sleep mode, and it is no longer possible to wake it up in the usual way. You should not panic at this moment, since in most cases the problem lies not in the fatal breakdown of the motherboard, but in a software failure or sticking of the mechanical element.

There are several proven methods to activate the device even with a completely broken physical key. MIUI, the shell from Xiaomi, provides various emergency launch scenarios that are not known to all users. Below we will discuss in detail the algorithms of actions that will help bring the gadget back to life without visiting the service center.

Before any manipulations, it is important to assess the current state of the battery: if the battery is completely discharged, none of the software will work. Connect the charger and wait at least 15-20 minutes, even if the charge indicator does not light up immediately. Sometimes the system takes time to accumulate the minimum level of energy to respond to external stimuli.

Forced reboot via keyboard combinations

The first and often most effective method is to use a hardware button combination to call the Recovery menu or fast boot mode, and even if the power button is damaged, the system can react to prolonged pressing of other keys, leading to a forced start, which works at the low-level firmware level, ignoring the state of the operating system.

To implement this method, you will need to find a volume button. Depending on the Xiaomi or Redmi model, the combinations may vary slightly, but the basic principle remains the same. You need to press the volume button and, without letting it go, connect the charging cable to the computer (not to the socket, but to the PC or laptop). USB-The port initiates the transition to Fastboot mode on many models.

If the device vibrates and you have an image of a hare repairing an android or a Fastboot logo on the screen, you wake up your phone. You can choose the Reboot option from this menu using volume buttons for navigation. Unfortunately, if the turn on button doesn't work at all, it can be difficult to switch in this menu, but the fact that the image appears confirms that the phone is alive.

There is also a combination to log in to Recovery Mode: Press the volume button "Up" and plug in the power cable. Some models require both volume buttons to be pressed simultaneously. If the screen catches fire, select the language (if available) and the option Reboot to System.

Use of the “Planned On and Off” function

If your Xiaomi smartphone is still on, but you're afraid it'll shut down and never start again, or if it's recently turned off and you have the ability to charge it quickly, you should use the built-in scheduler feature. It's a regular MIUI tool that allows you to set the time of the device's automatic start. It's the only reliable insurance for the future.

To activate this feature while the phone is still running, go to settings. The path usually looks like: Settings → Battery → Battery (icon in the corner) → Scheduled on and off. Here you need to set a time, for example, 5 minutes ahead of the current moment. Once the phone turns off (or if it is already off, but has a charge), it will try to turn on at a predetermined time.

It's important to understand the limitation of this method: it only works if the battery has a minimum charge left. If the phone is completely dead, the timer will not work, because it requires energy to count the time, so this method is ideal for prevention or situations where the device has not yet run out of charge, but the button is already floundering.

💡

Set two alarm clocks at 1 minute intervals. On some versions of MIUI, the alarm clock can also wake the device from deep sleep, even if the power button is not working.

Starting through a PC connection and ADB-team

For advanced users who had on the smartphone was pre-enabled debugging USB, There's a way to run through a computer. This method requires drivers installed. ADB (Android Debug Bridge on PC. If debugging was active before the phone stopped responding, the chances of success are very high.

Connect the device to the computer through USB-Open the command line or terminal on the PC in the folder with the installed ADB. Enter a command to check the connection:

adb devices

If a device with device status appears on the list, it means that the connection is established. To try to reboot or turn on, use the command:

adb reboot

In some cases, if the phone is in standby mode, this command can get it out of sleep. However, if the phone is completely shutdown, the adb command will not work because the Android operating system is not running.

adb reboot bootloader

After hitting the bootloader, you can try to restart the phone with standard menu tools or the command fastboot reboot.

Alternative methods: Charging and external influences

Sometimes the problem is solved by a banal but effective method of shaking the system through a change in power status. Some Xiaomi models have a feature: when you connect the charger to the phone turned off, if you pinch a certain combination, you start. Try to connect the charging, and then quickly press the volume button "Up" or "Down" several times.

There is also a method that involves battery discharge to zero: Leave the phone with a connected charge for a long time (for example, overnight), even if it shows no signs of life. Sometimes the power controller locks at deep discharge and it requires a long low-power current to "push." After 6-8 hours, try again applying the combination of buttons.

If the power button is physically stuck (for example, after moisture or a fall), you can try to gently tap the area around the button or slightly press it from different sides, while connecting the charging.

💡

The combination of a long charge (over 6 hours) and a sudden change in the circuit state (disconnecting/connecting the cable) often wakes up the power controller, even if the button is physically faulty.

Setting up screen control without a power button

If you've managed to turn your phone on in one of the ways I've described, your next challenge is to make sure it doesn't turn off by accident anymore, and make it easy to use without a button. MIUI has a number of settings that minimize the need for a physical key.

First, turn on the “Double-touch to turn on/off screen” feature. It’s on the way: Settings → Additional features → Double-touch. Now, you just need to tap the screen twice to activate the display. You can use the “Block” widget on your desktop or the “Complete Process” feature in the menu of recent apps to turn off.

Second, set a minimum time before going to sleep (Settings → Lock screen → Sleep mode) so that the phone will turn off the screen itself when you are not using it. It is also useful to activate the lift to turn on (Settings → Lock screen → Lift to activate).

p>The third important step is to install an assistant app if standard features aren't enough. There are utilities that add a software turn-on button to the screen or notification curtain. However, be careful: these applications require constant permissions and can consume a battery.
