How to turn on Xiaomi smartphone if the power button does not work: the full guide

Introduction

A broken power button on a Xiaomi smartphone is one of the most unpleasant breakdowns that can leave the device completely inoperable. You're used to pressing a physical key to unlock the screen or turn on the phone after it's discharged, but what if it stopped responding? The reasons can be different: from banal clogging of the mechanism to damage to the plume or control chip.

In this article, we’ll look at all the ways Xiaomi can turn on without a power button, from simple methods using a charger to advanced technical techniques with ADB and service teams. It’s important to understand that the effectiveness of each method depends on the phone model (Redmi Note 10 Pro, POCO X3, Mi 11, etc.), the version of the MIUI firmware and even whether the phone has been turned off or simply locked, and we’ll also tell you how to avoid repeated breakdowns and when to contact the service center.

If your Xiaomi doesn't respond to the power button, don't panic -- 80 percent of the time, you can solve the problem yourself without disassembling the case, and let's start with the easiest and safest ways.

1. Checking for obvious causes: charging and mechanical damage

Before you start complex manipulations, make sure that the problem is really the power button, not a dead battery or a temporary system failure.

• 🔌 Connect the original charger and leave the phone on charge for at least 30 minutes. Even if the indicator doesn't burn, the battery could run out of power, and it takes time to wake up.
• 🔍 Check the power button for physical damage, such as cracks, dents, or fluids. Sometimes the button sticks because of dirt, clean it carefully with a toothpick (not a metal object!).
• 📱 Try pressing the button from different angles. Sometimes the contacts oxidize unevenly, and pressing the side may work.
• 🔄 Reboot the phone forcefully by clamping the Power Button combination + Volume up 10 to 15 seconds. Some models (POCO F3, Redmi K40) This will work even if the button is broken.

If the phone is not showing any signs of life after this, move on to the next section. Note: if the charging indicator flashes red or orange, this may indicate a critically low charge or battery error, in which case you will need a Quick Charge charger (for example, the original adapter from Xiaomi on 18W or 33W).

⚠️ Note: Do not use left-hand chargers with non-standard connectors (e.g. Micro-USB instead of Type-C) this can damage the power controller and completely fail the phone.

2. Including through connection to PC or laptop

If the phone is dead or turned off but reacts to a charge connection (e.g., a battery indicator appears), you can try turning it on via a computer connection.This method works because some Xiaomi models automatically turn on when an active one is detected. USB-linkage.

Instructions:

1. Connect your phone to a PC or laptop using the original USB Type-C cable (or Micro-USB for older models).
2. Wait for the sound signal to appear on the computer (indicates device recognition).
3. If the screen is black, press the combination of Volume up + Volume down for 5-7 seconds. On some devices (Redmi 9, POCO M3) this will cause a forced boot.
4. If the phone vibrates or the MI logo appears but no further loading is going, try holding Volume up to log in to Recovery Mode.

If this method does not work, try using another one. USB-port on the computer (preferably) USB 3.0) or check the cable for damage, sometimes it helps to connect through an externally powered hub, as it delivers more current to the port.

💡

If the phone is defined by the computer as an "Unidentified Device", try installing Mi PC Suite or Qualcomm QDLoader drivers (for Snapdragon-based devices).

3.Use of OTG-cable

One of the little-known but effective ways to enable Xiaomi without a power button is to use the power button. OTG-This method works because when you connect peripherals, the system can trigger a screen to wake up even if the physical button is faulty.

What you need:

• 🔌 OTG-cable (or Type-C adapter) → USB-A).
• 🖱️ USB-mouse (wired or wireless with a USB-receiver).
• 🔋 Charged phone (at least 5-10%).

Step-by-step:

1. Connect. OTG-cable to the phone and to the other end — USB-mouse.
2. Wait 10 to 15 seconds. If the screen is on, move the mouse cursor, and that unlocks the phone.
3. If the screen is black, try pressing any button on the mouse or spinning the wheel.
4. On some models (POCO X3 NFC, Redmi Note 8 Pro) after connecting the OTG, you need to pin the Volume up + Volume down for 3-5 seconds.

This method doesn’t work on all devices, but has a high chance of success on smartphones with Qualcomm Snapdragon processors (e.g. Redmi). K20 Pro, Mi 10T). If the mouse doesn’t help, try connecting. USB-keyboard and press Enter or Space key.

⚠️ Warning: Do not use wireless mice/keyboards with Bluetooth connection – they will not work without prior settings. USB-receiver!

4. Enable via the service menu (Engineer Mode)

If the phone is turned on but the power button is not responsive to pressing (for example, to lock/unlock the screen), you can use the service menu (Engineer Mode), which is suitable for devices that are already booted into the system, but can not turn off or restart in the standard way.

How to open Engineer Mode on Xiaomi:

1. Open the phone app and enter the combination: ##4636##
2. In the menu that appears, select Testing.
3. Go to Buttons or Hardware.
4. Click on the virtual Power button – this simulates the pressing of the physical key.

If the standard code doesn’t work, try alternative combinations for different versions of MIUI:

• 📱 ##3644633## - To check the sensors and buttons.
• 🔧 ##284## — button test (works on Redmi) 5/6/7 series).
• 🔄 ##7594## Forced reboot (only for older models) MIUI 8–10).

Note that the service menu may vary depending on the firmware version. On new devices (MIUI 13/14), some codes may be blocked for security reasons.

Make sure your phone is at least 20% charged | Use the original keyboard to enter codes | Don't interrupt the button testing process | Write down the working codes for your model-->

5. Forced download via ADB (for advanced users)

If previous methods didn’t help, and the phone is determined by the computer in Fastboot or Recovery mode, you can try turning it on using Android Debug Bridge (ADB), which requires pre-configuration, but it is one of the most reliable for devices with a power button that is not working.

What you need:

• 🖥️ Computer with drivers installed ADB and Fastboot.
• 🔌 Original. USB-cable (preferably from the set).
• 📱 Included debugging by USB on the phone (if it has been activated before).

Instructions:

1. Connect your phone to your PC and open Command Prompt (or Terminal on Mac/Linux).
2. Enter the command to check the connection: adb devices If the device is determined, proceed to the next step. If not, try the command: fastboot devices
3. To force the screen to turn on, use: adb shell input keyevent 26 (code 26 corresponds to the power button).
4. If your phone is in Fastboot mode, try rebooting to the system: fastboot reboot

If USB debugging has not been enabled before, this method will not work, in which case only hardware repair or Test Point use remains (see the next section for more details).

⚠️ Note: Fastboot commands can cause data resets if the phone is in mode EDL (Do not use them unless you are sure of your actions!

💡

ADB-Teams only work if they are debugged USB has been activated in the developer settings (Settings) → The phone. → Version. MIUI — press 7 times).

6. Hardware methods: Test Point and disassembly of the phone

If the software didn't help, and the power button is physically faulty (for example, a plume broke off or a controller burned down), then you have to resort to hardware methods. This is an extreme measure that requires disassembling the phone, and we recommend it only to users with experience in electronics repair.

Method 1: Test Point (testing points)

Test Point is a special pin on the motherboard that forcibly turns the phone on in EDL mode, a method often used to firmware bricks.

How to find Test Point on Xiaomi:

• 🔍 On most models (Redmi Note) 8/9/10, POCO X3) Test Point is located next to the SIM card connector or under the back cover.
• 📌 These are usually two small contacts signed as TP, EDL or GND.
• 🛠️ Use tweezers or a needle to close, and then plug the phone into your PC, which should be defined as Qualcomm. HS-USB QDLoader 9008.

Method 2: Directly connect the power button

If the button has moved away from the board, but the chip itself is working, you can temporarily solder the wires to the contacts of the button and simulate the press.

1. Take your phone apart (instructions for your model can be found on YouTube or iFixit).
2. Find the power button plume (usually it goes from the top of the board to the side key).
3. Carefully solder two wires to the contacts of the button and briefly close them.

Warning: improper disassembly can lead to damage to the plumes or disconnection of contacts. If you are not sure of your skills, you should contact the service center. The cost of replacing the power button in official Xiaomi services ranges from 800 to 2000 rubles (depending on the model).

7. Contacting the service center: when necessary

If none of these methods worked, it is likely that the problem lies in a hardware malfunction that cannot be fixed on its own.

• 🔧 The power button has physically fallen off or its plume has been torn.
• ⚡ The phone does not respond to charging (no indication, does not warm up).
• 💻 The computer does not detect the device in any mode (Fastboot, Recovery, EDL).
• 🔥 On the board, blackened elements or traces of oxidation are visible.
• 📵 The phone vibrates, but the screen does not turn on (there may be a problem with the display or plume).

How to choose a service center:

Xiaomi’s official services in Russia and CIS can be found on the website mi.com/ru/service/location. Average repair prices:

• Replacement of the power button: 1000–2500 ₽.
• Replacement of the button plume: 1500–3000 ₽.
• Diagnosis of the fee: 500–1000 ₽.
• Flip-through EDL: 1000–2000 ₽.

Before the service visit:

1. Make a backup copy of the data (if the phone is turned on somehow).
2. Check if the center has Xiaomi authorization (this guarantees the use of original spare parts).
3. Check the reviews about the service on Yandex.Maps or 2GIS.

⚠️ Warning: Some artisanal workshops offer cheap repairs but use non-original buttons or low-quality glue, which can cause re-breaking in 1-2 months. Official services give a warranty of 3 to 12 months.
