You pick up your Xiaomi, but it doesn't respond to the push of the power button? The screen stays black and the charging indicator doesn't burn? Things get complicated if the power button breaks physically or the smartphone runs out of power. But don't panic: even without a working button, you can turn Xiaomi on in a number of ways, from simple charging manipulations to using hidden engineering modes.
In this article, we will discuss 5 proven methods to help “reanimate” your device, from basic techniques for beginners to advanced technical solutions. Importantly, the effectiveness of the method depends on the model of the smartphone (Redmi Note 10 Pro, POCO X3, Mi 11, etc.), battery status and cause of malfunction. If the phone is completely discharged and does not respond to charging for more than a day, first try to “wake” it through a high-current charger.
Warning: some methods require disassembling the device or using a PC. If you're not sure about your skills, you better go to a service center. But if you're willing to do it yourself, read on.
1. Initiation through the charger (the “hard reset” method)
The easiest way is to use high-current charging (from 2A and above), suitable if the smartphone is dead or “hangs” when you turn off. USB-cable.
Step-by-step:
- 🔌 Connect Xiaomi to charging and leave for 15-30 minutes. Even if the indicator does not burn, the battery can gradually accumulate charge.
- ⏱️ After 30 minutes, press the switch for 10-15 seconds. Sometimes this helps to break through the lock.
- 🔄 If the screen is not responding, turn off the charger, wait 10 seconds and plug again.
- 📱 On some models (Redmi 9, POCO M3) Helps combination: Charging + Volume up button (hold 20 seconds).
⚠️ Warning: If the indicator doesn't light up after an hour of charging, the problem may be a faulty battery or power controller.
2. Use of button combinations (emergency mode)
Many Xiaomi models support hidden button combinations that allow you to turn on the device without a power button. These combinations trigger Fastboot or Recovery Mode, from where you can restart the system.
Popular combinations for different models:
| Xiaomi model | Button combination | The result |
|---|---|---|
| Redmi Note 8/9/10 | Volume up + Loud down (hold 10 seconds) | Fastboot launch |
| POCO X3/F3 | Loudness down + Charging (hold 15 seconds) | Entrance to Recovery |
| Mi 11/12 | Volume up + Charging (hold 20 seconds) | Forced reset |
| Black Shark 4/5 | The game button (Shark) + Volume down | Emergency activation |
If the combination worked and you hit Fastboot, select Reboot using volume buttons and confirm the selection (usually with the power button, but if it is broken, plug in). USB-plug-in).
Try a different combination for your model.
Check if the volume button is stuck

Wait 1-2 hours on charging before trying again-->
3. Connect to PC via ADB (for advanced users)
If your Xiaomi has previously enabled USB debugging, you can enable it via your computer using the Android Debug Bridge (ADB) tool, a method suitable for devices that have ever connected to a PC in developer mode.
Instructions:
- Install ADB and Fastboot Tools on PC.
- Connect the switched off Xiaomi to your computer via USB.
- Open the command line (Win + R → cmd) and type: adb devices If the device is defined, execute: adb reboot
- If Xiaomi doesn’t respond, try the command for forced reboot: adb shell reboot -p
⚠️ Attention: If debugging is on USB It's not activated beforehand, it's not going to work, and it's useless if the smartphone is completely discharged.
What if the PC can’t see Xiaomi?
4. Testpoint closure (for experienced users)
If the power button is physically faulty, you can temporarily close the contacts on the motherboard by simulating a press, a technique that requires disassembling the device and minimal electronics skills.
How to find test points:
- 🔍 On most Xiaomi models, test points are located near the battery connector or under a metal screen.
- 📌 Usually it is two small contact areas with inscriptions. PWR_KEY, KPP or POWER_ON.
- 🛠️ To close, use tweezers, a screwdriver with an insulated handle or a special wire.
Step-by-step process:
- Turn off the battery (if possible) for 10 seconds, then plug it back in.
- Find the test points on the board (for precise location, look for circuits for your model, for example, the Redmi Note 7 has them next to the camera).
- Short-term (for 1-2 seconds) close contacts. If the smartphone shows signs of life (vibration, backlight), immediately connect the charger.
⚠️ Warning: Incorrect circuiting can lead to short circuit or damage to the board!
💡
Before disassembling the smartphone, take a picture of the location of all the plumes and screws. This will help to collect it back without errors.
5. Contacting a service center: when nothing helps
If all of these methods fail, the problem may be more serious than it seems:
- 🔋 Faulty battery (blown, deep discharge).
- 🔌 Power controller damaged (frequent problem after falls).
- 🛠️ Oxidation of contacts on the motherboard.
In such cases, self-repair is fraught with a complete failure of the device. It is better to contact the official Xiaomi service or a trusted repair center. The average cost of diagnosis is from 500 rubles, replacing the power button - from 1,500 rubles (depending on the model).
How to choose a service:
- ✅ Check reviews on Yandex.Maps or 2GIS.
- ⚠️ Avoid workshops that offer “quick repairs in 10 minutes” – this often means poor quality work.
- 📄 Require a warranty for repairs (minimum 3 months).
💡
If Xiaomi doesn’t turn on after falling or getting moisture, self-repair attempts can make the problem worse.
