The power button on Xiaomi does not work: reasons and 7 working ways to repair

A broken power button on a Xiaomi smartphone is one of the most frustrating breakdowns that can completely paralyze a device. You can't turn the phone on, turn it off, or even reboot it if you freeze. But don't rush to bring it to the service center: 70 percent of the time, you can solve the problem yourself without having special skills.

The causes of malfunction range from simple clogging of the mechanism to serious hardware failures. In this article, we will examine all possible scenarios, from software glitches to physical damage, and give step-by-step instructions with visual clues. We will pay special attention to the Redmi Note models. 10/11/12, POCO X3/X4 mi 11/12, where the problem is most often encountered.

Important: If your Xiaomi doesn’t respond to the power button but it’s charging (an indicator is on or a battery icon appears), the chances of recovery without disassembly are 85%.

1. Software glitches: how to turn Xiaomi on without a power button

In 30 percent of cases, the button stops working because of system errors, not physical failure. If the phone is dead to zero or freezes after an update, the button mechanism may be functional, but it is locked at the software level.

Method 1: Forced resetting

On most Xiaomi models (except flagships with Snapdragon 8 Gen 2) will work a combination of:

Press the volume button up + the power button for 10-15 seconds

If the screen flashes or a logo appears MI — The problem is the software. If you don't have a reaction, try an alternative combination:

Volume up + Loud down + Power (hold 20 seconds)

Method 2: Connecting to charging

Connect your phone to the original charger and wait a minute. 10-15. On some models (e.g. Redmi) 9A or POCO M3) at low battery charge, the power button is blocked until it is reached 5% If it's through the 15 The charger will appear for a minute - wait at least 20% Try to turn on the phone with a long press (2-3 seconds).

Method 3: Incorporation through ADB (advanced)

If you have had the debugging enabled USB In the developer settings, you can try to turn on the phone through the computer:

1. Connect Xiaomi to PC via USB.
2. Open the command line and type: adb devices If the device is defined, execute: adb shell reboot

This method only works if the phone was previously connected to that PC and allowed debugging.

2. Physical reasons: what to do if the button is jammed or not pressed

If the software methods didn't work, the problem is probably mechanical.

Reason 1: Moisture or dust intrusion

Xiaomi's power button is the most vulnerable place to contamination. Even if the phone hasn't sunk, condensation from temperature swings or dust can eventually block the mechanism.

• 🔹 The button is pressed with difficulty or "fails"
• 🔹 Crunch heard when pressed
• 🔹 The phone only turns on with 5-10 try

What to do:

1. Blow the button with compressed air (cleaning tank). Hold the cylinder vertically at a distance of 5 cm!
2. If you have access to isopropyl alcohol (90%+), put on 1-2 drops on a cotton swab and gently wipe the gap around the button.
3. Do not press the button for 12 hours - let the liquid evaporate.

Cause 2: Mechanical damage

Blows, falls, or heavy pressure on a button (such as in a pocket) can cause:

• 🔧 Disconnecting the button plume from the motherboard
• 🔧 Deformations of the metal jack (springs under the button)
• 🔧 Cracks on the board in the contact area

In this case, self-repair is possible, but will require disassembly of the phone. If you do not have experience, it is better to contact the service - the cost of replacing the button in official Xiaomi centers starts from 800 rubles.

💡

Before disassembling, take a picture of the location of all the plumes and screws – on Xiaomi, screws of different sizes are often used, and it is easy to confuse them.

3. Alternative ways to power Xiaomi without a power button

If the button fails completely, but the phone is working, you can turn it on bypasses, which work even if the screen is black (assuming the battery is charged).

Method 1: Using a Quick Charge Charge

Some models (Redmi Note 10 Pro, POCO F3) Supports forced on when connected to fast charging:

1. Connect the original RAM with Quick Charge 3.0 support+.
2. Hold the volume button for 30 seconds.
3. If the Fastboot menu appears, select Reboot with volume buttons and confirm with the power button (if it works even a little) or just wait for the automatic reboot.

Method 2: Through OTG-cable

If you have OTG-adapter, we can plug in USB-mouse:

1. Connect the phone to OTG-adapter and mouse.
2. On the lock screen (if it appears), move the cursor and click on the turn on button.
3. If the screen is black, try pressing the left mouse button 10 times in a row - sometimes this simulates pressing the power button.

Method 3: Through the Service Menu (for experienced ones only)

On some models (Mi 9, Mi 10) you can turn on the phone through the engineering menu:

##4636##

But this method only works if the screen responds to touch.

✅ Checked the charging response.

✅ I tried a forced reset.

✅ Cleaned the dust/moisture button

✅ Checked the switch-on through OTG/mouse

✅ Make sure the battery is charged (indicator is on fire)

Step 4: Assembly

Put the phone back together. Make sure you:

• All the plumes are tightly connected.
• The screws are twisted into their seats (don't confuse the length!)
