Expert methods of enabling Xiaomi with a power button that is not working

When a Xiaomi smartphone refuses to respond to the push of the power button, it often takes the user by surprise: A discharged battery combined with a faulty physical switch turns the device into a useless piece of plastic and glass. However, it is too early to panic: there are hardware and software ways to start the system, even if the mechanics have failed.

First of all, you need to understand the nature of the breakdown. If the button is just stuck or has a bad contact, the chances are high. If the plume is completely broken inside the case, the situation is more complicated, but connecting to the power source and then entering special commands often allows you to bypass the lock. In this article, we will examine proven techniques from simple actions to the use of debugging interfaces.

Now, consider that today's Redmi and Poco smartphones have different bootloader logics, and what works on the old MIUI 10 model may not work on the new HyperOS shell, so it's important to try each of the algorithms below consistently, starting with the safest ones.

Use of the automatic activation function when charging

The simplest and most affordable method, which works on the vast majority of Xiaomi lineup devices, is based on a regular system function many users don’t know, but when you plug a completely off phone into the network, it can automatically start if the battery has been deeply drained.

To do this, you'll need an original or certified power supply and cable. Connect the device to the socket and leave it for 15 to 20 minutes. If the battery was zero, the phone will first show the charge indicator, and then, when a certain voltage threshold is reached, the system will initiate the boot process itself.

The effectiveness of the method depends on the firmware version. In older versions of MIUI, this feature worked more slowly. In newer updates, manufacturers often remove auto-start for safety reasons, so that the phone does not turn on in your pocket or bag.

💡

Use a powerful power supply (minimum) 18-20 W), since fast charging can activate the power controller earlier than low-current USB-device.

If you don't start automatically, try waking up the screen. Connect your phone to charge, wait for the battery logo or percentage to appear, and then quickly tap or swipe on the screen several times, which on some models emulates the pressing of the power button.

The method of connecting to the computer and the Fastboot mode

If simple charging didn’t work, you can try Fastboot or Recovery modes, which are low-level modes that often respond to volume button combinations even when the power button is broken, if you choose the right connection time.

The idea is to apply voltage to certain USB contacts when you connect to your PC, you need a computer with Xiaomi USB Driver installed and a good quality cable. The algorithm requires a certain sleight of hand.

• 🔌 Connect one end. USB-cable to your computer, and don’t put the second one in your phone.
• 🔊 Press the Volume Up button and hold it.
• ⚡ Without releasing the volume button, connect the cable to the smartphone.
• 🐰 If you are lucky, the hare logo in the repair hat will appear on the screen, which means the entrance to the Fastboot.

⚠️ Warning: If your phone has entered Fastboot mode but you can't get out of it because of a broken button, don't panic.Put the Volume Up and Volume Down buttons on both the buttons on the phone. 10-15 In some models, this causes a forced reboot.

You can do the same thing by pressing Volume Down, and you can get into the Recovery (Main Menu) menu, and if the screen catches fire and shows the menu in English, you're on the right track, and you can choose from this menu the Reboot option, which will restart the system in normal mode.

Use of the ADB-remote-launch commands

The most professional way, which requires pre-preparedness, but gives the maximum result: If your phone has been pre-enabled debugging over USB (USB Debugging), you can send a command to turn on directly from the computer, this method works even if the phone is completely off, but connected to the power (in the waiting state of charging).

You'll need ADB (Android Debug Bridge) to work, download the Platform Tools from the official developer's website and unpack it on your PC. Connect your phone to your computer. If the device is determined, open the command line in the ADB folder and type the following command:

adb reboot

This command sends a signal to the power controller to start the system. If the phone is in deep sleep or is turned off but has a residual charge, it should turn on. In some cases, especially on custom firmware or root-rights, a more specific command may be required to emulate the press:

adb shell input keyevent 26

The 26 code on Android is the same as the Power button. However, it’s worth remembering that if the phone is turned off completely (not in sleep mode), the standard ADB may not see the device, in which case the team specific to Qualcomm chipsets helps, but it requires special drivers and often only works if the phone is already partially active.

Hardware closing contacts (for advanced)

If software is powerless, then you have to do "surgical" surgery, which is only for those who are willing to remove the back cover of the device, and it's about directly closing the contacts of the power button on the motherboard or on the plume.

You'll need a thin tweezer, a metal needle, or a thin screwdriver. After carefully opening the case (preheating the screen perimeter with a hairdryer or on the heating pad), you'll need to find the plume going to the side button. Often, just close two contacts on the connector of the plume where the button comes.

Close contacts in a short time, simulating a click. Tweezers should not be kept long so as not to damage the power chain. If the phone is turned on, immediately switch to setting the "Schedule Enablement" function to avoid repeating the procedure.

⚠️ Warning: Opening the case automatically deprives you of warranty. If the phone is warranty, take it to the service center - replacing the power button is inexpensive and quick.

Scheduled inclusion as a preventive measure

If you've managed to turn your phone on in one of the ways I've described, you should start prevention immediately, and the main task is to set up an automatic turn on so that the next time you run out, the phone will come alive.

There's a built-in scheduler in the MIUI and HyperOS shell. Go to settings, look for Battery or Advanced Settings, and there's a schedule switch on and off. Set a time, like 07:00 a.m., and select the days of repetition.

• 📅 Set your turn on time 10-15 minutes before you usually wake up.
• 🔋 Make sure your phone is charging at night if the battery is drained.
• ⏰ Check that the alarm does not conflict with the system settings of energy saving.

This feature is critical for owners of devices with damaged buttons, it allows the phone to initiate the boot of the OS without having to physically affect the body, and it is also worth turning off the phone completely in favor of hibernation, if this option is available in your version of the software.

What to do categorically can not be done

When trying to reanimate a device, users often make mistakes that make repairable failures fatal, and understanding the limitations will help keep the device intact.

Don't try to heat your phone with a hairdryer to high temperatures in the hope of warming the contact. Lithium-ion batteries can swell or ignite when overheated, and don't often plug and disable the power cable with jerks, which can lead to oxidation or burnout of the charge controller in the connector.

If you use third-party button emulator apps (root required), make sure they are safe. Malware can block the bootloader or steal data. Use only proven tools from XDA Developers repositories.

💡

The safest solution for frequent button problems is to replace the service plume or use the autostart function, rather than constantly using crutches.
