How to restart Xiaomi Redmi Note 4 without the power button: step-by-step instructions

Introduction: Why the power button fails and what to do

The power button on the Xiaomi Redmi Note 4 is one of the most vulnerable parts of the device. Over time, it can stick, stop responding to presses or completely fail due to mechanical wear, dust or liquid. If your laptop suddenly stopped turning on and the button does not respond to presses, do not rush to carry it to the service center. In most cases, the reboot can be performed software-based, without disassembling the case.

In this article, we’ll look at all the possible ways to reboot the Redmi Note 4 without using a physical power button, from standard keyboard shortcuts to BIOS and external devices. It’s important to understand that some methods require pre-tuning (such as enabling the USB wake-up function), so if your laptop is still working, prepare it for possible crashes in advance.

If the device is completely discharged or is not showing signs of life, first check the charging and cable — sometimes the problem lies in the banal lack of power.

Method 1: Keyboard combinations for forced reboot

The easiest method is to use hotkeys that emulate the power button press. On the Xiaomi Redmi Note 4 (as on most Windows laptops), the following combinations work:

• 🔄 Ctrl + Alt + Del → In the menu that appears, select "Reboot." It works if the system is not completely frozen.
• 🖥️ Alt + F4 → On your desktop or in the Explorer, select "Reboot" in the drop-down list.
• ⚡ Win + X → Completion of work → Reboot. Quick access to the power menu.

If the laptop is stuck and does not respond to the keyboard, try holding the power button for 10-15 seconds (even if it does not press properly). Sometimes this works due to mechanical contact inside the case. If the keyboard does not work, too, move to the next method.

Method 2: Reboot via BIOS (if the laptop is powered on but not booting Windows)

If the Redmi Note 4 is turned on (lights are on, the fan is spinning), but does not load the operating system, the problem may be a BIOS or bootloader failure, in which case resetting the BIOS settings to the factory will help:

1. When you turn on your laptop, press F2 or Del several times (depending on the BIOS version) to enter the settings menu.
2. Go to Exit and select Load Default Settings (or similar).
3. Save the changes (F10) and confirm the reboot.

If the BIOS doesn’t respond to the keys, try removing the battery for 30 seconds (with a removable battery) or disconnecting the laptop from the network and holding the power button for 20-30 seconds to reset the residual charge.

⚠️ Attention: Reset BIOS It will return all settings to factory settings, including how you boot your devices. If you have a non-standard OS (like Linux), you may need to reset the bootloader after the reset.

Method 3: Wake up via USB or LAN (if the function is enabled)

Many Xiaomi laptops, including the Redmi Note 4, support Wake-on-LAN or Wake-on-USB, which allows you to turn on your device over the network or via a network. USB-The port, however, requires that:

• 🔌 The function was activated in advance in BIOS (Power Management → Wake on USB/LAN).
• 💻 The laptop was connected to the charger (for the USB-wake-up).
• 🌐 Wake-on-LAN requires a second computer on the same network.

If the conditions are met, try:

1. Connect the charger to the laptop.
2. On another PC, send the Magic Packet through a program like WakeOnLan (for the first time). LAN) or plug in USB-device (keyboard/mouse) and press any button.

If the laptop doesn't respond, the function is likely disabled, in which case only hardware methods remain.

💡

To prepare your laptop for such situations, turn on Wake-on-USB in advance. BIOS and set up a program USB WakeUp (available for Windows) will allow you to wake the device even from the state of the switched off via the USB-cable.

Method 4: Connecting an external keyboard or mouse

If the built-in keyboard does not work, but the laptop shows signs of life (lights are on, the sound of the fan is heard), connect the external USB-keyboard or wireless mouse (via Bluetooth or USB-adapter:

• 🖱️ If the mouse is working, right-click on the desktop → Create → Label → Shutdown /r /t 0 and run the file.
• ⌨️ On the external keyboard, press Win. + R, type cmd, then execute the command: shutdown /r /f /t 0 Flag. /f It will forcefully close all programs.

If the laptop does not respond to connected devices, check if they are not disabled. USB-port BIOS (Sometimes it happens after a failure. In this case, only the resetting will help. BIOS hull-breaking.

Method 5: Hardware reset (if the laptop does not turn on at all)

If the Redmi Note 4 is not showing any signs of life (the indicators are not burning, the keyboard lighting is not working), then only the hardware reset remains.

1. Disconnect the laptop from the network and remove the battery (if it is removable).
2. Remove the back cover (a cross screwdriver will be required).
3. Find the reset button on the motherboard CMOS (usually signed CLR_CMOS or JCMOS) And press it on. 10 seconds.
4. If the button is not available, remove the CMOS battery for 5-10 minutes.
5. Collect a laptop and connect the charger - the device should turn on.

Disconnect the laptop from the network

Remove the battery (if removable)

Prepare a screwdriver and antistatic bracelet

Take a picture of the location of the plumes before disassembly

What do you do if nothing helps?

If none of these methods work, the problem may be more serious than it seems:

• 🔋 A motherboard malfunction (for example, a bridge or power controller has burned down).
• 🔌 Power supply problems (check the charger on another laptop).
• 💾 Damage to the bootloader or hard drive (try connecting) SSD op-ed).

In these cases, self-repair can make the problem worse. Contact an authorized Xiaomi service center — especially if the laptop is guaranteed. The cost of diagnosis usually does not exceed 500-1000 rubles, and repairs will cost less than buying a new device.

If your Redmi Note 4 doesn’t turn on after a drop or liquid hits, DO NOT try to turn it on – it can short circuit.
