How to turn on Xiaomi Redmi 5 Plus without a power button: all the ways from charging to disassembling

The broken power button on the Xiaomi Redmi 5 Plus is one of the most common hardware problems with this smartphone. Users often experience the phone suddenly stop responding to a press, freeze off or only turn on after multiple attempts, ranging from a banal moisture hit under the key to wear of the microswitch or damage to the plume.

In this article, we will discuss all possible ways to turn on the Redmi 5 Plus without using the power button – from the simplest methods with a charger to complex manipulations through the power button. ADB Each method has been tested on real devices and has its own nuances: somewhere you need a computer, somewhere you need a special cable, and in some cases even a regular battery will help. It is important to understand that some methods can lead to data loss or aggravation of the breakdown, so we will describe the risks in detail and give recommendations for minimizing them.

If your Redmi 5 Plus doesn’t turn on at all (no vibration, no charge indicator), first check the battery and charger. In 30% of cases, the problem is not in the button, but in a dead battery or damaged battery. USB-For diagnosis, try connecting your phone to another cable and power supply for 10 to 15 minutes — sometimes enough to give the device signs of life.

1. Energizing through the charger (the easiest way)

If the power button on the Redmi 5 Plus doesn't work, but the phone still reacts to the network connection (vibrates, the indicator lights up), try to turn it on through charging. MIUI, which in some cases automatically starts the system when a power source is detected.

What you need: original or high-quality charger (5V/2A), USB-Avoid cheap Chinese cables, which may not provide stable voltage, and the phone will not turn on.

• 🔌 Connect the Redmi 5 Plus to the charger and leave it for 10-15 minutes.The charging indicator should light up red or orange.
• ⏳ If after 15 minutes the phone does not turn on on its own, try holding the volume button (+) In some cases, it causes the system to restart.
• 🔄 If nothing happens, turn off the cable, wait 30 seconds and plug it again.
• 📱 If the Fastboot or Recovery menu appears on the screen, then the phone is partially working - go to the next section with instructions for exiting these modes.

⚠️ Note: Do not use chargers with higher voltages for this method 5V (This can damage the Redmi 5 Plus power controller, especially if the battery is already worn out.

This works about 40 percent of the time, but it depends on the battery and the firmware version. MIUI (below 10) the chance of successful inclusion is higher, as there are less stringent requirements for hardware checks at launch.

💡

If the phone vibrates or the indicator lights up when connecting to charging, then the problem is precisely in the power button, not in the motherboard.

2.Use of Recovery Mode for Forced Enablement

If Redmi 5 Plus doesn’t turn on in the usual way but reacts to button combinations, you can try entering Recovery mode and starting the system from there.This method is suitable if the power button is partially triggered (for example, only when pressed hard) or the phone is getting stuck in a reboot cycle.

Recovery Login Combination: Press the Power Button at the same time + Volume up button (+) Hold for 8-10 seconds until the Mi logo appears. If the power button doesn't work at all, try holding the Volume only. + And plug in the charger -- sometimes it works.

• 🔧 In the Recovery menu, select Reboot. → Reboot to System (use volume buttons for navigation and power button for confirmation). If the power button is not working, connect the phone to your computer - sometimes the choice is confirmed automatically.
• 🔄 If the system doesn’t start, try doing Wipe Cache Partition (does not delete user data, only clears the cache).
• 🚨 In the extreme, choose Wipe. Data/Factory Reset, but keep in mind that this will completely remove all data from your phone.

⚠️ Note: If the E:cannot mount error appears in the Recovery menu /cache or E:failed to mount /data, This may indicate damage to the memory partition, so don't reset the data, because it will make the problem worse. ADB or.

If you’re successfully logged in to Recovery but can’t confirm your choice because of a power button that’s not working, try connecting your phone to your computer and using the adb reboot command via your console.

3. Including through ADB (for advanced users)

The method using Android Debug Bridge (ADB) This is a good option if Redmi 5 Plus has previously included debugging. USB And the phone has been connected to a computer at some point, and this is one of the most reliable ways, but it requires some preconfiguration.

What you need:

• 🖥️ Computer with installed Xiaomi drivers and package ADB Tools.
• 🔌 USB-cable (preferably original).
• 📱 Phone that is defined by a computer in Fastboot or Recovery mode.

Step-by-step:

1. Connect the Redmi 5 Plus to your computer.
2. Open the command line (Win) + R → cmd) and type: adb devices If the phone is identified (a serial number appears), move to the next step. If not, try reconnecting the cable or installing the drivers again.
3. Enter the command to reboot: adb reboot If your phone is in Fastboot mode, use: fastboot reboot
4. If the system doesn't start, try clearing the cache: adb shell recovery --wipe_cache

Install Xiaomi drivers|Download ADB Tools from the official website|Enable debugging on USB on the phone (if you had access)|Use the original USB-cable|Check the connection of the adb device command-->

If ADB The device can't see it, but the computer makes the connection sound, try it:

• 🔄 Restart your computer and phone.
• 🔌 Connect the cable to another USB-port (preferably) USB 2.0 on the back of the PC).
• 🛠️ Install drivers manually through Device Manager (select Mi) ADB Interface).

⚠️ Note: Do not use fastboot erase or fastboot flash commands without fully understanding their operation. Improper application can permanently lock the bootloader or erase critical memory partitions.

If ADB It doesn't help, but the phone is defined in Fastboot, you can try flashing stock firmware through the Mi Flash Tool, but this is an extreme measure, since it requires an unlocked bootloader and leads to data loss.

Hardware method: closing the contacts of the power button

If the software fails, you have to mechanically turn on the power button through the contacts, which requires disassembling the phone and is only suitable for those who are willing to take risks or have experience with electronics.

What you need:

• ⚒️ Plastic blade or mediator for opening the body.
• 🔧 Screwdriver. T3 or T4 (For the Redmi 5 Plus screws).
• 🧲 Thin metal object (clip, tweezers) for closing contacts.
• 📸 Camera or phone to capture the process (so as not to confuse details during assembly).

Step-by-step:

1. Turn off your phone (if it still reacts).
2. Remove the back cover by slapping it with a plastic blade on the bottom edge (where the charging connector is located). Be careful, the lid is attached to the latches.
3. Unscrew all the screws that hold the metal plate above the battery.
4. Carefully disconnect the battery plume (it is under the black film).
5. Find the contacts of the power button on the motherboard – they are located next to the upper edge of the board and signed as PWR_KEY or POWER_SW.
6. Shortly (for 1-2 seconds), close the contacts with a metal object. The phone should vibrate and start loading.

What can't be done:

• 🔥 Close contacts for too long (more than 3 seconds) – this can burn the power controller.
• 🛠️ Using a screwdriver or other thick metal objects - the risk of touching neighboring components.
• 🔋 Connect the battery back if the phone didn’t turn on the first time – first check if there are any circuits left.

⚠️ Warning: If the phone doesn't respond after the contacts are closed but it warms up, disconnect the battery immediately! This is a sign of a short circuit on the board.

If the method worked, but the power button still doesn't work, you can use the phone temporarily, turn it on through the closure of contacts. However, permanent solution will require a change of button or plume - read about this in the next section.

5. Replace the power button or plume: when nothing helps

If all previous methods failed, the problem is probably the physical breakdown of the button or the plume connecting it to the motherboard, which would require disassembling the phone and replacing the part.

Signs that a replacement is needed:

• 🔍 The button is not pressed at all (no clicking).
• 💧 Under the key, traces of oxidation or moisture are visible.
• 🔌 The phone is turned on only after multiple presses or in a certain position.
• 🔧 Closing contacts on the board does not give results.

What will be needed to replace:

• ⚒️ Setting screwdrivers (T3, T4, cross-section).
• 🔍 Loop or magnifying glass (contacts are very small).
• 🧲 Tweezers and plastic spatula.
• 🛒 New power button or plume for Redmi 5 Plus (can be ordered on AliExpress or in service centers).
• 🔥 Dryer or soldering station (if you need to solder contacts).

Where to buy spare parts:

Step-by-step instructions for replacement:

1. Take the phone apart as described in the previous section and get to the button plume.
2. Disconnect the plume from the motherboard (usually it is attached to the latch).
3. If the problem is in the plume, replace it with a new one. If in the button itself, carefully remove it from the case (it may be glued).
4. Set a new button or plume, observing the polarity.
5. Collect the phone in reverse order, making sure all plumes are tightly connected.

💡

Before replacing the button, take a picture of its location in the case - new parts sometimes go without mounts, and they need to be correctly orientated.

If you are not sure about your skills, you should contact the service center. The cost of replacing the power button in Xiaomi is about 1000-1500 rubles, but they give a guarantee for work. Self-repair can result in damage to the plume of the display or motherboard if you act negligently.

6. alternative methods: charging from another battery and USB OTG

If neither method worked, two lesser-known, but sometimes effective, methods can be tried:

1. Connect to a charged battery from another Redmi 5 Plus

If you have a second Redmi 5 Plus (or someone familiar with the same phone), you can temporarily connect its battery to your device.

• 🔋 Remove the battery from the donor phone (it should be charged 50% or more).
• 🔌 Connect it to your Redmi 5 Plus while observing polarity (red wire plus, black minus).
• 📱 The phone must turn on automatically or after the contacts of the power button are closed.

2.Use of USB OTG keyboards

If you have USB OTG-cable USB-So you can try emulating the power button through the keyboard, and this method doesn't work on all firmware, but it sometimes helps:

• 🔌 Connect. OTG-cable to the phone and to it - keyboard.
• 🖥️ Click on the Ctrl keyboard + Alt + Del or Power (if there is a button).
• 🔄 If the phone is in Fastboot mode, the keyboard can help select the menu item.

⚠️ Warning: Connecting non-original batteries or using damaged ones OTG-The cables can overheat or short circuit. Do not leave your phone unattended during such experiments.

These are more of an ambulance than a full-fledged solution, and they can help once or twice, but you still have to fix your phone to keep working.

Frequent Mistakes and How to Avoid Them

When trying to turn on Redmi 5 Plus without a power button, users often make mistakes that exacerbate the problem, and here are the most common ones and how to avoid them:
