Introduction: Why the power button doesnโt work and what to do
The broken power button on the Xiaomi Redmi Note 5 (codenamed whyred) is one of the most common hardware problems with this smartphone. According to service centers, up to 12% of owners experience a power failure after 2-3 years of operation, the reasons are diverse, from banal mechanical wear to moisture under the key or damage to the plume after a fall.
Complicating matters, even the basic steps of turning on, restarting or stepping out of deep sleep are impossible to do without a power button. However, not all is lost, there are software and hardware workarounds to regain control of your smartphone. In this article, we will discuss 5 proven methods of rebooting the Redmi Note 5 without using the power button, including ways for unlocked and locked bootloaders.
Important: Before applying any instructions, make sure that the problem is in the button, not in a discharged battery or a damaged display plume. If the screen does not respond to touch, but when you connect to charging, an indicator appears, it is likely that the power button is to blame.
Method 1: Reboot via charging connection (the easiest way)
If your Redmi Note 5 is dead or dead, but the power button is not working, try initializing charging first, which works 60 to 70 percent of the time unless the problem is related to hardware damage to the board.
Here's what we need to do:
- ๐ Connect your smartphone to an original or quality charger (current at least 2A). USB Type-C, which came with the kit.
- โณ Leave the device on charge for at least 15-20 minutes. Even if the indicator does not burn, there may be hidden recharging.
- ๐ฑ After 20 minutes, try pressing and holding the volume button for 10-15 seconds, in some cases, this causes a forced reboot.
- ๐ If the screen catches fire but the phone doesnโt load beyond the Mi logo, release the button and wait for the automatic reboot (can take up to 5 minutes).
This method works thanks to the features of the Qualcomm Snapdragon 636 power controller, which is installed in the Redmi Note 5. When connecting to charging, the emergency wake mechanism works if the battery level exceeds 5%. If the method does not work, move to the next one.
โ ๏ธ Note: Do not use "left" chargers with higher current 2.4A - it can damage the power controller on the board. Xiaomi's original adapter has an output voltage 5V/2A.
Method 2: Forced reboot via ADB (for unlocked bootloader)
If your Redmi Note 5 has USB debugging enabled and the bootloader unlocked, you can restart the device via your computer using the Android Debug Bridge (ADB) tool, which requires pre-configuration but gives you full control of the system.
Step-by-step:
- Download and install Googleโs Platform Tools (includes adb and fastboot).
- Connect your smartphone to your PC through USB-cable (preferably original).
- Open the command line (cmd) in the folder with the platform-tools.
- Enter the command to check the connection: adb devices If the device is determined, move on. If not, install Xiaomi drivers or try another one. USB-port.
- Execute the command to force reboot: adb shell reboot or to switch to fastboot mode: adb reboot bootloader
If the Redmi Note 5 doesnโt respond to commands, try waking it up via ADB:
adb shell input keyevent 26 # power button simulation
adb shell input keyevent 3 # unlock screen (if PIN is enabled)This method only works when you are actively debugging over USB, and if you have never turned on this mode, move on to the next one.

Method 4: Hardware reset via test points (for power users)
If the software methods didnโt help and the power button failed completely, then the hardware reset through test points is left, which requires disassembling the smartphone and is only suitable for those with experience with electronics.
Warning: Incorrectly closing the test points can cause the motherboard to fail completely, and only use this method as a last resort!
Instructions for Xiaomi Redmi Note 5:
- Turn off the smartphone (if it is turned on, wait for the battery to drain completely).
- Remove the back cover by unscrewing 12 T3 screws (use a magnetic screwdriver!).
- Disconnect the battery plume (gently attach the connector with a plastic blade).
- Find two test points on the motherboard (usually signed as TP or circled in white). For the Redmi Note 5, they are located next to the charging connector.
- Close the points with tweezers or a screwdriver for 5-7 seconds, then plug the battery back in.
- The smartphone should go to EDL mode (emergency firmware). You can then flash the device through the Mi Flash Tool.
| Action. | Risks. | The alternative |
|---|---|---|
| Close of test points | Damage to the board with improper closure | Contact the service center |
| Battery disconnection | The slack break in the careless extraction | Use a plastic spatula |
| Firmware through EDL | Losing data with complete flashing | Create a backup before the procedure |
โ ๏ธ After closing the test points, the smartphone will go to 9008 mode (Qualcomm) EDL). To get out of this mode, you will need firmware through the Mi Flash Tool with an authorized Xiaomi account. Without experience, this can lead to a โbrickโ of the device.

If none of these methods worked, the problem could be more serious than just a faulty power button.
| Symptoms. | Possible cause | Decision |
|---|---|---|
| The smartphone does not respond to charging, there is no indication | Damaged power controller or battery plume | Diagnostics in the service center, replacement of the plume / controller |
| The device vibrates when charging is connected, but does not turn on | The problem with firmware (soft-brick) | Firmware via Fastboot or EDL |
| The screen flashes, but the image is missing. | Display plume or graphics chip damaged | Replacement of a plume or diagnosis of a motherboard |
| The smartphone is heated, but not turned on | Short circuit on the board or battery failure | Battery replacement, board check on microscope |
If you do not have experience in electronics repair, it is better to contact a specialized service. The average cost of replacing the power button with a Redmi Note 5 in Russia is 800-1500 rubles (depending on the region and the service center), In some cases it is cheaper to buy a used motherboard (about 2000-3,000 rubles) and replace it completely.
