How to turn on Xiaomi phone without the power button: all ways

When the power button on a Xiaomi, Redmi or Poco smartphone stops responding, users are often taken by surprise: the screen goes out, the device goes into standby mode, and the usual activation method stops working, this can occur due to mechanical damage to the plume, moisture or a software failure that blocks the power sensor.

But you shouldn't panic ahead of time, because Android has several alternative ways to start the device. In most cases, you can activate the smartphone simply by plugging it into a power source or using specialized debugging tools. It's important to understand that the way you solve the problem depends on whether the battery is completely drained or the phone is just gone into a deep sleep.

In this article, we will discuss in detail all known ways to force Mi devices to start, we will look at both software methods that require a connection to a computer and hardware manipulations that can be performed at home. The most effective way often depends on the specific model and version of the MIUI shell installed on your device.

Using the charger and PC to activate

The easiest and safest method that works 90% of the time if the battery isn't completely dead. USB-The power controller receives a signal to connect an external source, which automatically initiates the process of loading the operating system on many Xiaomi models, even if the button is physically faulty.

You'll need a proper cable and power supply to do this. It's advisable to use the original adapter, because it provides the right current for the controller to respond correctly. Connect your smartphone to the network and wait a few minutes; if the Mi logo or charging indicator appears on the screen, then the device has begun the wake-up process.

Sometimes the standard connection to the socket does not work immediately. USB-The voltage difference and the specific data signal can wake the power controller where normal charging is powerless. If after connecting to the PC, the smartphone vibrated or made a sound, but the screen remained black, try quickly pressing the volume key combination, which will be discussed below.

💡

Use a cable with a running data transmission, not just a charging cord, as a signal from a computer often wakes up the power controller more effectively than current from the socket.

It's worth noting that if the battery is discharged to zero, it can take the phone 15 to 30 minutes in the connected state before it can turn on. During this period, the screen can stay black, which does not mean a malfunction. Lithium polymer batteries require a certain minimum voltage to start the controller, and until it is dialed, the system will not start.

Launching through Recovery and Fastboot mode

If a normal charging connection fails, you should try to put the device into service modes. Recovery mode is a diagnostic environment built into every Android smartphone. You can get into it by squeezing a certain key combination at the time of power supply. For most Xiaomi devices, it is a combination of a volume button and a cable connection.

The process is as follows: press the Volume Up button (volume up) and, without letting it go, connect the smartphone to the computer through the USB-Hold the button until the Mi logo or the Recovery menu comes up, and if the screen lights up and a menu with a choice of language or options appears, then the display and matrix are good, and the problem lies in the on button or software freeze.

1. Make sure the phone is connected to the PC (not to charging).

2. Press the Volume Up button.

3. wait for the vibration or logo to appear.

4. Release the button when the menu appears.-->

Similarly, Fastboot mode, which is often used for flashing, is used to press the Volume Down button when you connect the cable. If the phone goes into Fastboot mode (the screen usually shows a bunny fixing an android), this confirms that the hardware is working. From Fastboot or Recovery mode, you can sometimes select the Reboot option, which will allow you to start the system in normal mode without using the Power button.

⚠️ Attention: When in the Recovery menu, be extremely careful with navigation. Volume buttons are used to move up and down, and the choice is made (in some versions) by long-term clamping or automatically.

Use of the ADB-commands to turn on the smartphone

For advanced users who have ADB (Android Debug Bridge) drivers installed on their computer, this method only works if the phone has previously enabled USB debugging and the device is at least partially responsive to a PC connection. ADB allows you to send system commands directly to the operating system.

To do this, you need to connect the phone to your computer and open the command line or terminal in the tool folder of the platform. If the device is identified, you can try sending a command to restart. Even if the phone is turned off, in some cases (especially if there is a residual charge) the command can initiate a start.

Enter the following command in the terminal:

adb reboot

If the standard command doesn’t work, you can try more specific options to restart specific services or the entire system. However, if the phone is completely powered down or is in deep sleep without a USB response, the ADB may not see the device, in which case the terminal screen will remain empty or no devices found error.

It is important to understand that the effectiveness of ADB depends on the state of the loader and drivers. If the ADB drivers are installed correctly, the computer can recognize the device even when it is off as a charger or drive, but not as a debugging device.

Mechanical methods and disassembly of the device

If the software is powerless, you'll have to physically impact the components of your smartphone. The internal power button on Xiaomi boards is a clock switch that closes the contacts on the motherboard. If the external plastic button unstuck or broke, you can try tapping directly on the mechanism itself.

To do this, carefully remove the back cover (if it is removable) or peel off the glass (on models with a glass back panel). Find the place where the power button should be located. It is usually on the side, in the upper or middle part of the body. Use a thin dielectric tool, such as a plastic shoulder blade or toothpick, to press the inner button.

• 🔧 Find the plug of the power button: it can be detached from the board, try gently inserting it back before clicking.
• 🔧 Check contacts: oxidation or dust may interfere with contact, wipe the area with alcohol (neatly, without fanaticism).
• 🔧 Close contacts: in extreme cases, you can carefully close contacts on the board with thin tweezers, simulating a press, but this requires skills and carries the risk of short circuit.

A common problem with Redmi and Poco smartphones is unplugging the internal plastic pad that transfers force from the external button to the mechanism. If you find that when you press the side edge of the button walks or doesn't get squeezed to the end, this is probably the case. A temporary solution might be to insert a small piece of foam or rubber between the button and the body.

⚠️ Warning: Any manipulations inside the smartphone case are carried out by you at your own risk. Careless movement of a metal tool can damage the plumes of the display or battery, which will lead to fire or complete failure of the device.

Specificity of Xiaomi, Redmi and Poco models

Xiaomi’s various product lines have their own design features that affect how they are turned on. Understanding these nuances can make things much easier. For example, in low-end models with plastic housing, buttons often fail faster because of backlash, whereas in flagships, the problem is more often in the software part.

The table below shows the features of inclusion for different series of devices:

Special attention should be paid to devices with a side fingerprint scanner, which is combined with the on button. In such models (Fingerprint Power Button), a malfunction of the scanner automatically means that the phone cannot be turned on in the standard way, only prolonged holding of the volume button in combination with charging, or soldering of the module in the service center.

The button doesn’t work physically.

Prevention and setting up of automatic switching

To minimize the risk of a phone being turned off in the future, you should set up an automatic turn on beforehand. The MIUI and HyperOS shells have an on and off scheduler feature. If you activate this option, the phone will turn on itself at a predetermined time, even if the power button does not work.

To set up, go to Settings → Battery → Planner (the path may vary depending on the OS version). Set a daily turn-on time, for example, at 7:00 a.m. This ensures that even if the phone runs out or freezes at night, it will try to start on its own in the morning if it has a charge.

💡

Setting up automatic on schedule is the only guaranteed way to “wake up” a phone without a button in the future if it goes into deep sleep.

It is also recommended to regularly check the state of the battery and avoid a full discharge to zero. Deep discharge is harmful to Li-Pol batteries and can lead to a situation where the voltage is not enough even to react to the connection of the charger. If you notice that the phone has become faster discharged or the button has begun to “stuck”, it is better to contact the service center in advance to replace the plume.

In conclusion, not responding to the power button is a nasty but often-solvable problem. Start with the simplest methods: connecting to a computer and pressing the volume buttons. If that doesn't help, move on to the more complex options with ADB or disassembly. The main thing is to act consistently and not to put too much physical effort into it so as not to make things worse.
