When the power button on Xiaomi’s smartphone stops responding, it can be taken by surprise at the most inopportune moment: the screen is gone, the device is gone into sleep mode, and the usual tap on Power does not produce any result. This causes panic, as access to contacts, photos and important applications is blocked, and calling standard reboot methods is impossible.
However, Xiaomi engineers have provided several workarounds for such cases. There are many software and hardware methods that allow you to start the system even with a completely broken physical key. In this article, we will examine all the proven methods, from simple manipulation of charging to the use of special computer utilities.
Before you bring a gadget into the service, you should try to restore access yourself. Often the problem is not a breakdown of the matrix or the processor, but a software failure or sticking contacts that can be eliminated without a soldering iron. Next, we will describe in detail the algorithms for the different versions of MIUI and HyperOS.
Using a computer connection as a trigger
The easiest and often ignored way to launch a smartphone is to use the system’s response to a power supply or PC connection. Many Xiaomi models automatically turn on or go into boot mode when voltage is detected on the contacts, even if the Power button is physically faulty. For this method, you will need a worker. USB-cable and computer.
Connect the switched off smartphone to USB-If the battery is completely discharged, leave the device on charge. 15-20 In some cases, the system will offer a menu of selecting the boot mode (Recovery, Fastboot, Normal Boot). If the screen is on fire but the phone is not loading, try to pinch the volume key combination if they work.
Importantly, this method doesn’t work on all firmware versions. In newer Android and MIUI updates, the autostart function when powered is often turned off for security and energy saving purposes. However, this is the first step worth taking, as it doesn’t require any additional tools.
⚠️ Warning: If the phone only vibrates or shows the Mi logo when you connect to your PC, but it doesn't load any further, you may have damaged system files.
If the standard connection didn’t help, try using it. ADB-To do this, the Xiaomi drivers and the Android platform must be installed on the computer. SDK Platform-Tools: Connect your phone and type a command to reboot in the command line, which often helps wake up a device that has been getting stuck in the black screen.
💡
Use the original cable to connect. Cheap cables can only transmit current, but not data, making it impossible to control the phone through a computer.
Launching through Recovery and Fastboot mode
Recovery and fastboot are low-level interfaces that are activated before the main operating system loads, and can be accessed by a combination of buttons, which is especially true if the power button is not working but the volume buttons are working, and this bypasses the standard boot cycle.
To enter Recovery Mode on the device turned off, press the Volume Up button and plug in the power cable. Some models require you to press both volume buttons simultaneously_recovery_ You can choose the Reboot option -> Reboot to System using volume buttons for navigation.
Fastboot mode is often used for flashing, but it can also serve as an entry point. Press Volume Down and plug in the cable. The Fastboot logo should appear on the screen with a picture of a rabbit fixing an android, and from there you can send a command through the computer to normal reboot.
Sometimes entering these modes requires precise timing. First, press and hold the volume button, and then, without letting it go, plug the cable in. USB. If you fail the first time, try changing the sequence or using another. USB-port.
Using ADB for remote inclusion
The Android Debug Bridge Toolkit (ADB) is a powerful tool for developers to control a device from a computer. If your phone has previously had USB debugging enabled, you can send a command to turn on or reboot without ignoring the physical button. It's a professional method that requires training.
To work, you need to install ADB Drivers and platform tools on your PC. Connect the phone (even if it's off but has a charge, or is in standby mode) and open the command line. Enter the adb device command to check the visibility of the device. If the device is displayed, you can use the adb reboot command to reboot.
adb reboot
If the phone is completely off and does not respond to the connection, the standard adb reboot command may not work because the operating system is not active. However, there is an adb reboot bootloader command that can initiate a bootloader to Fastboot, from where it is easier to start the system.
What if the ADB can’t see the phone?
If the computer doesn't recognize the device, try installing Google USB Driver universal drivers or Qualcomm specific drivers. Also check if USB debugging is enabled in the developer's settings. If the phone is turned off "to zero," ADB won't help - you need a charging or button. It's important to understand that the ADB method only works if the phone has not been completely de-energized (battery is pulled out or deep discharge) and the system is at least partially functional. In the case of a full "brick," software methods may be powerless without hardware intervention. Hardware stimulation techniques and hardware buttons need to temporarily restore the contact, and allow the device to switch on the physical components to be switch on. Try the "massage" method of the button. Intensively, but without fanaticism, press the switch a few dozen times, which can help break the oxide layer on the contacts inside the mechanism. You can also try to push the body slightly in or near the button area while you plug the charger in at the same time, and another way is to use a magnet. Some smartphone models have Hall sensors or respond to magnetic fields in the button area (although this is more commonly the case with bookcases. ⚠️ Note: Do not use liquid (alcohol, WD-40) To clean the button if you're not ready to disassemble the phone, the fluid can leak under the screen or onto the board, causing the short circuit and the device to break down. If you have disassembly skills, you can carefully remove the back cover (if it is removable) or display module and close the contacts of the switch button with tweezers directly on the board. This is the most reliable way to check if the button is alive at all. Tweezing contacts with tweezers simulates pressing. Set up automatic on a schedule. One of the most useful features of MIUI and HyperOS is the ability to automatically turn on and off the smartphone on on a schedule. If your phone is now, but you are afraid that the button will stop working permanently, or if you managed to turn it on one of the button without pressing on the right button in the button above. Activate the option to turn on and set a convenient time, for example, 08:00 am. Also, you should activate the function Double tap to turn on the screen. Go to Settings -> Always on screen and lock screen -> Double tap to turn on / off the screen. This will wake the device without using side keys, extending the life of the button mechanism. To navigate inside the system, use Assistive Touch (floating button). Include it in the menu Additional functions -> Floating buttons. You can assign to the virtual button action "Block the screen", "Per off the phone, the table is completely compatible with the use of the computer, and the use of the device, the device, the use of the device is completely compatible with the use of the device, the use of the device, the device, the use of the device, the device, the use of the device, the use of the device, the device, the device, the use of the device, the use of the device, the use of the device, the use of the device, the use of the device, the use of the device, the device, the device, Below is a table that will help you navigate the available solutions to the problem. Method Necessary conditions Efficiency Data Risk Charging (USB/Power socket) Failed battery Low/Mediocre No button combination (Recovery) Operating volume buttons High No ADB Teams Included debugging by USB Average No Contact Closing Skills Disassembly Tools Very High Medium (damage to plumes) As you can see from the table, the safest and most affordable method is to use a combination of volume buttons, if they are functioning. ADB It's good for advanced users, but it requires some training, and you should only use physical intervention as a last resort, and if none of these things work, it's probably hardware, like the button plume has gone off, the connector has oxidized, or the board itself has gone out of order. In this case, a visit to the service center is required to replace the plume or to carry out the procedure of rebolling (restoration of contacts) of the power controller. 📊 Did you manage to turn on the phone without a button?Yes, through charging Yes, through RecoveryNo, carried in the service Phone does not turn on at all Frequently asked questions (FAQ) Can you completely remove the power button on Xiaomi software? You can not delete the button function, since it is tied at the level of the kernel and bootloader. But you can minimize your use by setting up Assistive Touch to lock the screen and setting up automatic turn on on schedule. To turn off your phone, use the Quick Access menu or voice assistant. What if your Xiaomi phone turns on but the screen is black? This may indicate a malfunction of the display or backlight, not a button. If the beeps are running and the screen is not on, it's a problem in the screen. Also try to connect the phone to the computer: if the PC is making the device's connection sound, then the system is working. Will the factory reset help if the button is not working? Reset (Wipe Data) can be done through the Recovery menu using the volume buttons for navigation. However, if the switch on button is not working physically, the reset may not solve the problem, since it is mechanical. Moreover, after resetting the phone will be difficult to turn it back on without a running button. How to turn off the phone without power button?
