When the power button on a smartphone stops responding, it often takes Xiaomi and Redmi owners by surprise: The device can be fully functional, have a charged battery, but remain black screen due to mechanical damage or sticking of the contact group.
In this article, we will discuss in detail the software and hardware methods for activating a gadget that will help you access data or fully start the device. Some solutions require a connection to the computer, others work solely from actions with the phone itself. It is critical to understand that if the phone is completely discharged (0%), no software method will work without initial power supply.
Before you go into complex manipulations, make sure that the problem lies in the button, and not in the deep discharge of the battery or a faulty charging port.If the charging indicator does not light up when you connect the cable, you may need to replace the connector or a long wait before trying to turn on.
Use of connection to computer and ADB
One of the most reliable ways to wake up a smartphone is to use debugging. USB, If it's been pre-activated in the developer settings, you'll need a computer to do that, USB-cable and installed drivers ADB. Connect the phone off to the PC and simultaneously press the volume key combination to try to enter bootloader mode.
If the screen reacts and shows the Fastboot logo, you can send a command to boot the system through the console. Open the command line on your computer in the platform-tools tool folder and type in the fastboot reboot command. This action will force the device to restart to normal operation.
If USB debugging has been enabled before and the phone is simply asleep and does not wake up, connecting to a charged computer can sometimes trigger automatic start-up, however, if the phone has been turned off completely software-based, this method will only work if there is residual charge and specific BIOS/Bootloader settings.
What to do if your computer can’t see your phone?
It is worth noting that the ADB method is only effective when the system is at least partially functional or in standby mode. For completely switched-off devices without pre-configured triggers, this method may not be useful without a physical one.
Triple pressing and alarm clock
In the MIUI shell, which is installed on Xiaomi, Redmi and POCO smartphones, there is a useful feature that allows you to turn your phone on schedule. If you set your alarm or alarm function in advance, the device will automatically start at a given time, even if it was completely turned off.
To test this possibility, you had to activate the option in the alarm menu in advance, but if the phone is already off and the button is not working, you can rely on built-in system timers that can work at a critically low charge level or when you connect the charger, if this function is provided by a specific version of the firmware.
- 🔔 Check if the alarm has been set before turning off the phone – some models start automatically.
- 🔌 Connect the original charger – sometimes the system reacts to the current by starting.
- 📱 Use the Triple Press feature if it is set to launch apps, but this only works when the screen is on.
If none of the software timers were set up in advance, this method, unfortunately, will not help to start the device from scratch.However, Xiaomi owners are advised to always keep the automatic alarm option on as insurance against breaking the button.
Enter Recovery Mode and Reset Settings
Recovery mode is a diagnostic partition available at the bootloader level, and you can usually access it on Xiaomi with a combination of the "Loud Up" and "Power" buttons. If the power button is not working, use the method of connecting to the computer: press "Loud Up" and connect it. USB-On some models, this triggers the Recovery menu without the need to use the switch on the PC.
Once you’re in the Recovery menu (usually a black screen with text or a MIUI Recovery graphics menu), you can control your phone using volume buttons for navigation. However, selecting a menu item or confirming an action often requires a short press of the power button. If it doesn’t work completely, this method can be dead-end unless the interface supports volume control only (which is rare).
There is an alternative entry to Recovery mode via the app, but it requires the phone to be turned on. So if you happen to be on the Recovery menu, try just waiting. Some systems automatically reboot after a certain time of inactivity, which can lead to a regular turn on.
☑️ Checking before entering Recovery
It is important to understand that Wipe Data will delete all your data, and only use this method if the information on your phone is not important or you have a fresh backup in the Mi Cloud.
Hardware methods and contact closure
When software is exhausted, you have to physically attack the device, which requires precision and understanding of what you're doing, and the idea is to close the contacts of the button plume manually, simulating a push, which requires removing the back cover (if it's removable) or gently bend the display module.
Find the plume that goes from the volume buttons to the motherboard, carefully disconnect it and inspect the contact area, you need to find the contacts that match the power button, and if you lock them with tweezers or a thin screwdriver for a split second, you send a signal to start the processor.
| Model of the device | Location of the plume | Type of connector | Difficulty of access |
|---|---|---|---|
| Redmi Note 8/9 | Side, under a plastic frame | Wide flat | Medium |
| Xiaomi Mi 11/12 | On the side, under the glass. | Narrow, fragile. | Tall. |
| POCO X3/NFC | Side, available after removal of the cover | Standard. | Low. |
| Redmi 9A/9C | Side face, removable cover | Easy access. | Low. |
If you are not confident in your abilities, it is better not to take risks, since a sloppy circuit can lead to a short circuit of the motherboard, in such cases it is safer to contact a service center to replace a button or a plume.
⚠️ Warning: Opening the case of the smartphone automatically deprives you of warranty. If the device is new, it is better to immediately carry it to an authorized service.
Use of external triggers and accessories
There are special external devices such as USB-triggers or "mouse" for the phone, which can emulate the taps. OTG (On-the-Go, you can connect USB-But for this to work on a phone that's turned off, the system has to be asleep, not completely shut down.
Some users resort to using magnets to try to influence Hall sensors or internal button mechanisms, but on modern monolithic Xiaomi smartphones this works extremely rarely and is more a myth than a working method.
A more realistic option is to use an automation app if the phone is on but the screen is broken or the touchscreen is not working. OTG-cable will allow you to manage the interface and set up auto-start applications or reboot.
💡
Buy it cheap. OTG-cable in advance - it costs a penny, but can save the situation if you stop working touchscreen or buttons, and turn on the phone urgently need to.
Keep in mind that working with connected accessories consumes the battery faster, and if you use this method as a temporary solution, keep an eye on the level of charge.
Prevention and Configuring of Alternative Inclusion
To avoid the problem of not being able to turn on in the future, you should prepare your Xiaomi or Redmi in advance for possible failures. First of all, set the alarm function and set the alarm for the near future, even if you do not need it.
It is also useful to activate the function "Double tap to turn on the screen" (if supported by the model), this will wake the phone without using the side keys. Go to Settings → Lock screen and activate the desired options.
- 📅 Set your daily alarm clock at 05:00 am as insurance.
- 🔋 Watch the battery, do not allow a full discharge to zero.
- 🛡️ Use a protective case that does not press the on button to prevent it from sticking.
Regularly restarting the device helps clear RAM and prevents freezes that may require forced button intervention.Try to restart the smartphone at least once a week.
⚠️ Warning: Do not leave your phone dead for a long time. Lithium polymer batteries can go into a deep discharge, after which the phone will not respond even to charging without special equipment.
