When Xiaomiβs favorite smartphone refuses to respond to its usual actions, it is always taken by surprise. It is especially unpleasant to realize that the physical power button, which is used dozens of times a day, has failed. Owners of the brandβs devices often face the problem of sticking, oxidizing contacts or completely mechanically breaking the key.
The current MIUI operating system and Android hardware platform offer many control scenarios beyond the standard circuitry. Engineers have laid out alternative ways to activate the device that bypass the damaged control. In this article, we will explore in detail all possible methods for launching the device, from software settings to hardware manipulation.
Before you take your phone to a service center, you should try to restore it yourself. There is a high probability that you will be able to turn on the phone right now using only a charger or a computer. We will look at both secure software methods and more complex options that require caution.
Using the charger and PC to activate
The easiest and most affordable way to start a smartphone with a power button that is broken is to connect to a power source. When you insert a cable into a USB Type-C or Micro-USB connector, the motherboard receives a signal to start charging. On many Xiaomi models, especially the older Redmi and Pocophone series, this process automatically initiates a screen turn on or even a full system boot if the device has been turned off.
However, if the phone is in deep sleep or completely off, simply connecting to the socket may not be enough. In this case, you need to create a simulated press. USB-The computer sends a voltage signal to a particular data line, which is sometimes perceived by the system as an event that requires a reaction. If the screen catches fire but the system is not loading, try pressing the volume buttons.
β οΈ Warning: If the phone gets hot or makes strange noises when connected to a charge, disconnect the cable immediately.This may indicate a short circuit in the button circuit that could damage the power controller.
In some cases, especially on devices with a discharged battery, the phone can only turn on after reaching a certain level of charge. Leave the gadget on charging for 15-20 minutes, even if the screen does not respond. After that, try the volume key combination, which we will talk about in the next section. It is important to use the original cable, since poor-quality wiring may not transmit the necessary signals for activation.

Use the original Xiaomi cable or certified analogue labeled 3A/5A. Cheap cables often only transmit current, ignoring the data signals needed to wake the controller.
Volume key combinations and Recovery login
If a standard network connection fails, you need to use hardware volume buttons. At the Bootloader firmware level, these buttons take priority and can activate the device even when the power button is not working. There are several combinations that are worth trying sequentially, holding them for 10-15 seconds after connecting the cable.
The first option is to press the Volume Up button. On many Xiaomi Mi and Redmi Note models, this action, when the charger is connected, puts the device into Recovery mode. In this menu, you can select the reboot option that will actually start the phone. The second option is to press the Volume Down button, which often leads to Fastboot mode. Although this is a firmware mode, on some versions of MIUI, exiting it through the menu can initiate a normal boot.
- π Connect your phone to a charger or PC.
- π Press the Volume Up button and hold for 15 seconds.
- π If you have a Recovery menu, select "Reboot to System".
- π If you see a picture of a rabbit, try to press both volume buttons simultaneously for 10 seconds.
It's worth noting that the response to these combinations depends on the version of MIUI and the model of the Snapdragon or MediaTek processor. On devices with MediaTek processors, sometimes the method of connecting to a PC with both volume buttons clamped down. If neither method helps, it is possible that the power button has physically closed the circuit, and the phone is in a state of constant waiting for a signal that is locked software.
βοΈ Verification of hardware response
Starting through a computer and ADB utilities
For advanced users who previously had USB debugging enabled on their smartphone, the most powerful software way to enable is open. Android Debug Bridge (ADB) toolkit allows you to send commands directly to the operating system or bootloader without passing physical buttons. This method requires a computer running Windows, macOS or Linux and installed drivers for Xiaomi.
The idea is to send a special command that forcibly restarts the device. Even if the phone is turned off but the battery is minimal, connecting to a PC running ADB can wake up the controller. You need to open the command line or terminal in the tool folder of the platform and enter the command to reboot.
adb rebootIf the device is in Fastboot mode (even if you donβt see the image on the screen), you can use the command:
fastboot rebootThis method is effective only if the phone has not been completely powered down (the battery has not gone to zero) and the software part is not damaged. the adb reboot command only works if the phone is on but the screen is not on, or if the device is in standby mode with active USB-For completely off phones, this method works less often, but it is worth trying, since some Xiaomi models when connected to a PC with installed ADB automatically try to establish handshake connection, which can trigger the inclusion.

The function "Switching on the alarm" as a preventive measure
One of the most useful but rarely used features in the MIUI shell is the ability to turn your phone on on schedule, a feature designed specifically for cases where the power button is unavailable or not working properly. If your phone is now off, this method, alas, won't help, but it's critical to set up immediately after you start the device in any way to avoid problems in the future.
To activate this option, go to the alarm settings. In each alarm menu or in the general time settings, find "Power on with alarm." When you activate this feature, the phone will turn on itself at a predetermined time, even if it was completely turned off. This is a salvation for those who have the switch on button over and over.
The adjustment is as follows:
- β° Open the Clock app and go to the alarm settings.
- π Select the right alarm clock or create a new one.
- βοΈ Find the βAlarm Switchβ and activate it.
- π Set a time when the phone should turn on automatically.
It's important to understand that this function depends on the motherboard's internal timer, which continues to work even when the phone is turned off as long as there is a minimum battery charge. If the battery is completely drained, the stash will reset and the phone will not turn on itself, so owners of broken buttons are advised not to allow the device to completely discharge.

The alarm clock autostart function is the only regular way to guarantee to turn on the phone without the power button, but it must be configured in advance.
Hardware methods and contact closure
When software is exhausted, it is left to physically affect the components of the device. This section is for users who are ready to remove the back cover of the smartphone. If the switch is broken mechanically (for example, a leg under the button broke off or the membrane oxidized), you can try to close contacts on the board manually.
It requires a thin tweezer or needle. Carefully remove the back cover (preheating the edge with a hairdryer or on a heating panel if the glue holds it strongly). Find the plume that goes from the switch button to the motherboard. Often the button is a separate module. Your task is to find the two contacts under the button itself on the board or on the plume and briefly close them with a metal object.
| Xiaomi model | Location of contacts | Risks. |
|---|---|---|
| Redmi Note 9/10 | On the side of the flexible plume | High risk of damage to the plume |
| Xiaomi Mi 11/12 | On a separate swing board | Hard access indiscriminately |
| Poco X3/NFC | Integrated into the volume plume | We need precision. |
| Redmi 9A/9C | Separate button on the board | Easy to close with tweezers |
Closing should be done with extreme care to avoid shortening adjacent paths, which can cause the power controller to burn. If you see that the button is just stuck, try to gently clean the contacts with 99% alcohol with a toothbrush. Often oxidation is the cause of the lack of contact, and cleaning brings the button back to life.
β οΈ Warning: Opening the case of the smartphone automatically voids the warranty. If the device is still in warranty service, do not resort to hardware methods, but contact an authorized center.
EDL and professional recovery
If none of the above methods worked, it may have gone into deep down or EDL mode.In this state, the device may be defined by the computer as a Qualcomm HS-USB QDLoader 9008, but the screen will remain black.
Closing test points is a more accurate analog of closing a button, but it causes the processor to go into boot mode, ignoring the state of the power button. Find the circuit (schematic) of your Xiaomi model on the Internet. The diagram will indicate the Test Points. By closing them and connecting USB, you will force the phone to turn on in firmware mode, from where you can sometimes initiate a normal boot.
But if the problem is that you have a physical cliff on the button, you can't software the phone to turn on, and the only solution is to replace the button plume, which is an inexpensive procedure that you can do yourself by ordering a part on the marketplace, or trust the wizard. The plume for most Redmi and Poco models is low, and the replacement process takes 15-20 minutes.
