When a Xiaomi smartphone refuses to respond to a standard power button press, it often causes a stupor, which can occur due to physical damage to the mechanism, moisture entering the body, or a system failure blocking the response of the touchscreen and buttons. Owners of Redmi and Poco series devices face this problem regularly, especially if the gadget is several years old.
But not responding to the Power button doesn't always mean that the device is completely out of order. There are a number of software and hardware methods that allow you to activate the system or at least enter the recovery mode to save data. It's important to understand that the effectiveness of each method depends on the current battery charge and the depth of sleep in which the smartphone is immersed.
In this article, we’ll look at all the launch options available, from simple charging connections to complex USB debugging manipulations. Critically, if the phone is dead to zero, no software method will work without recharging for at least 30 minutes. Don’t rush the device into service, try to play the scenarios listed below.
Use of connection to computer and charger
The easiest and often ignored way is to use the motherboard’s response to the voltage. Xiaomi’s current power controllers are programmed to automatically activate the screen or vibrate when the power source is connected, even if the device is turned off.
Try connecting your phone to the original charger, and if the battery is not deep discharged, the screen may light up, showing the charge indicator, at which point you need to quickly unlock the device if the pin is installed, or confirm the system boot.
A more effective method is to connect to a computer through USB-When connected to a PC, the smartphone receives a signal that the data line is present, which sometimes causes a more active reaction than just feeding current from the outlet. USB.
- 🔌 Connect the original cable USB-C to the computer port, not to the charging unit.
- 🔋 Leave the device on charge at least for 15-20 minutes before attempting to switch on.
- 💻 Use the ports. USB 3.0 (blue) on the back of the system unit for stable current supply.
- 🔄 Try flipping the cable plug in the phone's connector, as the contacts may have oxidized.
⚠️ Warning: If the phone starts to heat up in the camera or battery area when you connect to charging, turn it off immediately.This is a sign of a short circuit inside the power supply chain, and further attempts to turn it on may cause a fire.

If the power button is physically broken, but the contacts on the board are intact, you can try to start the device through combinations of volume buttons. In Xiaomi and Redmi smartphones, booting into special modes is often triggered by these keys when you connect to a PC.
To enter Fastboot mode, which allows you to reflash the device or check its status, you need to press the Volume Down button. Hold it, connect the phone to the computer, and the logo with the android hare repairing the screen should appear on the screen, indicating a successful entry into mode.
The Recovery menu uses a Volume Up button to get into the Recovery menu, and the algorithm is the same: press the button, connect the cable to the PC, and if the screen catches fire and the menu appears in multiple languages, the hardware and motherboard are functioning.
In Recovery mode, you can try to select "Reboot" to restart the system as normal. However, if the power button does not work physically, navigation through the menu can be difficult. In some models, the touch screen in this mode does not work, and without the power button, you can not select a menu item.
- 📉 “Loudness down” button» + USB-cable = Fastboot mode (for firmware).
- 📈 “Loudness up” button» + USB-cable = Recovery mode (for resetting).
- ⏱️ Press the button until the cable is connected and hold it still. 5-10 seconds.
- 🛑 If the screen doesn’t light up after 30 seconds, release the button and try again.
⚠️ Note: Entering Fastboot or Recovery mode does not guarantee that the phone will turn on as normal, but is used for diagnostics and recovery, not for everyday use.
Using USB Debugging (ADB) to Start
The most professional method that requires prior training is the use of a tool. ADB (Android Debug Bridge. This method will only work if the phone's settings have previously activated "Debugging by Debugging" USB» The computer has access to the device.
The method is to send a software command from a computer that forces the operating system to boot, which bypasses the need to physically press a button, as the signal goes directly to the power controller through the power supply. USB-protocol.

adb reboot recovery
What if the ADB can’t see the device?
If the command returns the "no devices found" error, then the debugging over USB is not enabled or the drivers are not installed. In this case, try installing Google USB Driver universal drivers or Qualcomm specialized drivers. Sometimes it helps to press the volume button when connecting the cable to put the phone into the mode available for PC.>Hidden text: If the command returns the "no devices found" error, then debugging over USB is not enabled or drivers are not installed.

In some Xiaomi models (especially the old Mi series), you can close contacts on the battery connector or test points (you can do this for a dangerous start). Damage risk method Required skills Charging efficiency from PC Low Basic Average button combinations Low Basic High ADB Teams Low Advanced High (if debugging is enabled) Contact closure Critical Professional Maximum ⚠️ Warning: Self-opening and closing the contacts automatically voids the warranty, and any careless movement can lead to the motherboard's irreversible failure. This method is only relevant if the phone is still on, but the button has stopped working, and you want to protect yourself from full discharge in the future. MIUI You have a built-in auto-enabled function, you need to go to settings, find the Battery or Advanced Settings section, and activate the Scheduled Tasks item».

If the screen is touch-responsive, but the power button is not working, you can set the screen to turn on with a double tap or a long press on the volume button, but if the phone is already off, these apps will not help start it from scratch. They are only effective for controlling the screen (waking up) in the operating system, they are useless for full-on from the off state, and it is worth mentioning the possibility of using the Mi Assistant in Recovery mode. If you managed to enter the Recovery through the volume buttons, connect the phone to the PC and open the browser. http://192.168.1.1:8080 (address may differ) to access the file system and try to back up the data before repair attempts. 💡Programmatic methods (ADB, Apps only work if the phone is at least partially functional. When the brick is complete, it's only repairing or closing contacts that helps. Frequently asked questions (FAQ) Can I turn on Xiaomi if the screen crashes and the button doesn't work?
