When Xiaomi’s smartphone refuses to respond to the physical Power key, it often takes you by surprise and causes panic. Mechanical wear, moisture, or software failure can cause the power button to stop working, but it doesn’t mean that the device is permanently out of order and requires an immediate trip to the service center.
There are many software and hardware workarounds that allow you to activate the gadget even when the button is not working. In this article, we will discuss in detail the proven methods that will help you run Redmi or POCO using the capabilities of the Android operating system and standard interface functions.
Before we get to the complex manipulations of the engineering menu, we should try simple actions, such as connecting the charger or using the alarm function. Sometimes the system simply “hangs” in deep sleep, and it requires an external impulse to wake up, which does not necessarily have to come from the physical key.
Use of the alarm function to activate
One of the easiest and most effective ways to wake up a smartphone is to use a built-in alarm clock: MIUI and HyperOS are designed to take precedence over standby mode, forcing the device to start at a predetermined time.
To implement this method, you need the phone to be charged and online.You can ask a friend to call you or set an alarm on your second phone if you have paired devices through the Xiaomi Home ecosystem.
When the signal goes off, the screen will light up, and you can quickly go to the settings menu to change the lock settings or launch the desired application, which is a temporary solution, but it gives you access to the system to save data.
⚠️ Warning: Make sure the alarm clock volume is not at zero, otherwise the phone may vibrate but won't wake the screen to interact.
This method is especially useful if the button is stuck or has poor contact and you need to urgently extract files or make an important call.
Connection to the computer and debugging mode
If the phone has previously been activated debugging over USB, then connecting to a computer can be the key to saving the device.
To do this, you’ll need a USB cable and a PC-mounted ADB (Android Debug Bridge) utility, which allows you to send commands directly to the operating system without having to go through physical control buttons.
The startup process is as follows: connect the phone to the PC, open the command line and enter the appropriate code to restart or turn on the screen. If the drivers are installed correctly, the device will respond to the command.
adb shell input keyevent 26This command emulates a short press of the power button, and if the phone was just in sleep mode, it will turn on, and if the device was completely turned off, this method may not work without first applying power.
What to do if your computer can’t see your phone?
Starting through connection of charger
The most common, but often ignored, way is to plug in the original charger. Many Xiaomi models automatically turn on when charging when the battery is completely drained or the phone is off.
Sometimes standard charging doesn’t give you the right boost, and then the help comes in unusual methods, for example, connecting to a powerful power supply from a laptop or using wireless charging (if the model supports such a function) can provoke a reaction of the power controller.
In some cases, a quick sequence of actions helps: plug in the cable, wait for the battery indicator to appear, and immediately try to unlock the screen or start the application if the system allows.
- 🔌 Use the original cable and power supply for maximum current.
- ⚡ Try connecting your phone to a working computer, not just an outlet.
- 🔋 Leave the device on charge on 15-20 minutes, even if the indicator does not burn.
If the phone vibrates when connected, but the screen remains black, it may be the display, not the button, so try to point the flashlight at the screen, and if you see a dim interface, the backlight is not working.
💡
Try connecting your phone to an external battery (Power Bank), a sudden surge in voltage when connected to a powerful source sometimes helps push the power controller.
Use of volume button combinations
Physical volume buttons often remain active even when the power button has failed, and combinations of these keys allow you to enter special boot modes such as Recovery or Fastboot.
While you can choose to reboot your system when you are in Recovery mode. While you usually need to press the on button to enter this menu, some models with a fully discharged battery automatically enter the recovery mode when you connect to a PC with the volume buttons pressed.
Try to press the volume button and connect the USB cable to your computer. If you're lucky, the phone will go to Fastboot mode, where you can choose the Start or Reboot option using the volume buttons for navigation.
⚠️ Warning: Do not select the Wipe Data option in Recovery mode if you want to save your files.
Some Redmi devices have a trick of plugging in to charge with a volume button pressed, which can put the smartphone into diagnostic mode, where it can sometimes be accessed by a regular system.
Special features and double tapping
There is a "Double Touch to Enable" or "Raise to Enable" feature in Android settings, and if you have time to activate one of these options before the button breaks, the problem is solved by simply touching the screen.
Check for these settings if the phone is still responsive to connections or alarms. Go to Settings → Lock screen and activate the desired features for future use.
Also worth paying attention to the function of “Gestural Management”: turning the phone swipe on the off screen is a convenient alternative to the mechanical button that prolongs the life of the smartphone.
If none of the features were enabled beforehand, this method won’t help start a phone off, but it will be a great solution to prevent problems in the future when you turn the device back on.
💡
Activating the functions “Double touch” and “lift” is the best preventive measure for users who have the button on the inclusion started to falter.
Table of methods of inclusion by condition
For the convenience of choosing your Xiaomi’s resuscitation strategy, we have compiled a table that will help determine the appropriate method depending on the current situation with the device.
| Condition of the telephone | Recommended method | Probability of success |
|---|---|---|
| Battery's dead. | Connecting to powerful charging | Tall. |
| Sleeping phone | Alarm or incoming call | Very high. |
| USB debugging enabled | ADB team with PC | Tall. |
| Full shutdown (Hard Off) | Combination of volume buttons + PC | Medium |
As you can see from the table, the success of the operation depends on the state of the phone at the time of the button failure. Software methods work only if the device was not completely de-energized.
What to do if nothing helps
If none of the software methods worked, it's likely hardware-related, which could be a push-off of the button plume, oxidation of the contacts on the board, or failure of the power controller.
In this case, the only solution is physical intervention, so you can carefully remove the back cover (if it is removable) and try to close the contacts of the switch with a thin conductor, simulating a press.
For modern monoblock smartphones POCO and Redmi will require disassembly of the case. If you do not have the skills of repair, it is better to contact the service where the button will be replaced or soldered the plume.
⚠️ Warning: Self-disassembly of the smartphone will deprive you of an official warranty.
Sometimes, a strong but careful push on the area of the button with your finger helps while connecting the charging, which can temporarily restore contact inside the mechanism and allow the phone to turn on.
