When your loyal Xiaomi Redmi suddenly stops responding to the power button, it always takes you by surprise. The black screen and lack of vibration can scare even the experienced user, but you should not panic. In most cases, the problem lies not in the fatal failure of the motherboard, but in a software failure or deep battery discharge that can be fixed on your own without going to the service center.
Before you look for a wizard, you need to do a primary diagnostic of the condition of the device. Often the reason that the phone does not turn on is a trivial error of the MIUI operating system or a power controller freeze. If you see a charging indication, but the screen remains dark, or the device does not show signs of life at all, the algorithm of actions will differ. It is important to consistently exclude simple options, so as not to waste time on complex manipulations.
The next steps depend on what exactly happened to your gadget in the last minutes before the breakdown, whether you installed an update, dropped the device or simply left it in the cold. Understanding the context will help you choose the right method of resuscitation. Below we will discuss all possible scenarios in detail and offer proven solutions for each specific situation.
Checking of the power supply and charger
The most common reason Redmi doesn't want to turn on is because of the power system. Lithium-ion batteries tend to go into a deep discharge if the device has been lying idle for a long time. In this state, the controller blocks charging in normal mode, and the screen may not light up even when connected to the network. You will need to leave the phone on charge for at least 30-40 minutes, even if the indicator does not catch fire immediately.
Do not exclude the malfunction of the charging cable or power supply. the use of non-original accessories with low current may not be enough to start the charging process of a fully sat down smartphone. Try replacing the cable, taking a larger power supply or connecting the device to your computer via a USB-Sometimes, changing the power source does wonders.
Notice the charging connector in the phone itself, which often gets dust, pile and contact oxidized, which prevents the current from flowing normally. Carefully, without using metal objects, clean the port. If the situation hasn't changed after cleaning and charging for a long time, maybe the problem lies deeper.
- 🔋 Leave your smartphone on the charger 40-60 minutes, even if the screen is black.
- 🔌 Try replacing the cable. USB and the power adapter for the known serviceable.
- 🧹 Visually inspect the charging connector for the presence of contaminants and oxides.
- 🌡️ Check the temperature of the device: the cold battery may not take charge.
⚠️ Warning: If the smartphone case starts to heat up or swell up during charging, immediately disconnect it from the network.
💡
Use only certified cables and power supplies. Cheap counterparts from markets often lack the necessary protection controllers, which can lead to voltage surges and motherboard failure.
Forced reset and static voltage reset
The Android operating system, like any complex program, is sometimes subject to critical errors that cause it to freeze. At this point, the phone may look turned off, but in fact it just locked in a cycling process or "hang" during the boot stage. The standard press of the power button in this case does not work, since the software controller does not respond to interrupts.
For most Xiaomi Redmi models to reboot, you need to press the power button and hold it for a long time, from 10 to 20 seconds. In some cases, you need a combination of buttons: press both the power button and the volume button. Hold them until you feel the vibration or see the Mi or Redmi logo on the screen, which is a process that resets static electricity from the motherboard and forcibly reboots the power controller.
If the first time it didn't work, don't despair. Try plugging your phone into the charger, waiting a few minutes and repeating the button procedure. Sometimes it takes several attempts to rock the system, and you can try plugging the device into your computer and clamp the volume control buttons when you connect.

Diagnostics through Recovery and Fastboot mode
If the screen is black, but when you connect to the computer, the device's connection sounds, the motherboard is alive, but the system is not booting, in which case you need to get into the processor's service modes. Recovery mode allows you to reset or remove problematic updates, and Fastboot mode is needed for flashing.
To enter the Recovery menu on a phone that is turned off, press the power button and the volume button. Hold them until the logo appears, then release the power, keep the volume up. If you are on a menu with several lines in English or Chinese (usually there are Wipe Data, Reboot items), then the display and touchscreen are good, and the problem is in the software. Here you can try to select Reboot to System.
Fastboot is activated by pressing the power button and the volume button. The android-fixing hare or FASTBOOT message should appear on the screen. If the phone is stable in this mode and the computer sees the device, that's a good sign. If the screen doesn't light up even in these modes, and the phone is warming up or vibrating, the display or the plume is probably damaged.
| Regime. | Button combination | Screen indication | Appointment |
|---|---|---|---|
| Recovery | Food + Volume Up | Menu with items (Wipe, Reboot) | Data reset, removal of updates |
| Fastboot | Food + Volume Down | Hare with android / inscription FASTBOOT | Fixing, deep recovery |
| Safe Mode | When downloading (depends on the MIUI version) | The inscription "Safe Mode" | Diagnostics of third-party applications |
⚠️ Note: The Wipe Data item in the Recovery menu completely deletes all user data (photos, contacts, apps). Use it only if other methods do not help and saving information is not a priority.

Problems with the display and touch screen
Sometimes the smartphone is working, it's making notifications, it's vibrating when you call, but the screen is completely black, and this is a classic symptom of a matrix failure of a display or a plume connecting the screen to the board, which often happens after a fall, even if there is no external damage to the body, and the shock wave could damage the fragile crystals of the matrix or move the contact.
You can test this theory by calling a phone number, and if you're going to beep, and then you hear the sound of the answer, but there's no picture, it's a 100% problem in the display, and you can also point the flashlight at the screen that's off, and if you see a dim image of the interface, it's a light that's gone, and in both cases, you need to replace the display module at the service center.
Another rare but possible cause is a software conflict of the display driver, in which case a reset via Recovery, described above, may help.
