How to restart Xiaomi RedmiBook 8 Pro without the power button: all working methods

Xiaomi RedmiBook 8 Pro laptop has stopped responding to the power button, and a reboot is urgently needed?The situation is familiar to many: mechanical failure of the power key, sticking contacts or a software failure make the standard way to launch inaccessible. Fortunately, even without a working Power button, there are at least 5 alternative methods of forced reboot - from simple key combinations to the use of hidden BIOS functions and external devices.

In this article, we will look at all the current methods, from the most secure (for example, through Ctrl+Alt+Del in Windows) to radical (hardware reset via the power connector). Importantly, some methods can lead to loss of unsaved data or even damage to the system if performed incorrectly, so before you start, read the warnings in each section and choose the most appropriate option.

If your RedmiBook 8 Pro is completely discharged or is not showing signs of life, check the charging first – plug in the original adapter and wait 15-20 minutes. In 30% of cases, the problem is not in the button, but in a dead battery or a malfunctioning power supply.

1. Reboot via keyboard (if laptop is on)

If the RedmiBook 8 Pro works but the Power button doesn't respond, try the standard keyboard combinations first.

There are two options available in Windows 10/11:

• 🔄 Soft reboot: press Win + X, then select Finishing or exiting the system → If the menu doesn't open, use Alt. + F4 on the desktop, select “Reboot” and confirm.
• ⚡ Forced reboot: pinch Ctrl + Alt + Del, in the menu that appears, click on the power icon (bottom right) and select Reboot».
• 🖥️ Through Task Manager: If the system is getting stuck, open Task Manager (Ctrl) + Shift + Esc), go to the File tab and select "Run a new task." Enter the shutdown command. /r /t 0 and press Enter.

On Linux (if you are installed on RedmiBook), use the terminal:

sudo reboot

Or the combination of Ctrl + Alt + PrtScr + R E I S U B (alternately, with a delay of 1 second) is a safe analogue of hardware reboot.

Save all open documents and projects |Close resource-intensive programs (games, video editor) |Disable external drives (flash drives, hard drives) |Make sure that the laptop is connected to the network (if the battery is discharged)

-->

⚠️ Note: If your laptop is stuck in the boot phase of Windows (a spinning circle or a black screen), the keyboard combinations may not work.

Hardware discharge through charger

If the RedmiBook 8 Pro doesn’t respond to either the keyboard or touchpad, but the power indicator is on or flashing, try hardware reset through the power supply.This method simulates battery extraction (which is impossible without disassembly) and resets the residual charge in the capacitors.

Instructions:

1. Disconnect the charger from the laptop.
2. Press the power button for 30 to 40 seconds (even if it doesn’t work mechanically, it will drain the capacitors).
3. Connect the charger back and wait 5-10 minutes. The laptop should automatically turn on or respond to the pressing of the keys.

If the power indicator doesn't light up, try another adapter (preferably the original Xiaomi with 65W or 100W power).

⚠️ Note: Do not use non-original chargers with voltages higher 20V — This can damage the power controller RedmiBook 8 Pro. the original adapter is marked Output: 20V≈3.25A.

3. BIOS login and forced reboot

If the laptop is powered on but not loading Windows (e.g., the Xiaomi logo or black screen hangs), try logging in to the BIOS and rebooting from there, which will help bypass a bootloader crash or hardware conflict.

To log in to the BIOS on RedmiBook 8 Pro:

1. Turn off the laptop (if it is on, press the power button for 10 seconds).
2. Press and hold the F2 key (or Del on some versions).
3. Turn on your laptop (if the button doesn’t work, plug in the charging – sometimes this triggers the process).
4. Release F2 when the BIOS menu appears.

In the BIOS interface:

• 🔧 Go to the Exit tab (or Save & Exit).
• 🔄 Select Reset to Default Settings (Default Settings Reset).
• 💾 Save Changes and Reset – This will reboot your laptop.

If the BIOS doesn’t open, try an alternative method: When you turn on, press the F12 (boot menu) and select Enter Setup.

4.Use of an external keyboard or mouse

If the built-in RedmiBook 8 Pro keyboard doesn’t respond (for example, due to drivers or a physical breakdown), plug in an external keyboard. USB-It's a keyboard or a mouse, and it allows you to control the laptop and initialize the restart.

Step-by-step:

1. Connect the keyboard to any free USB-A or USB-C port (when using the hub, make sure it supports data transfer, not just charging).
2. If the laptop is turned on, click on the external keyboard Win + X → U → R (reboot).
3. If the laptop is turned off, try turning it on through an external keyboard – sometimes this works even when the built-in button is faulty.

For Mac keyboards (if you connect from a MacBook): use Control + Option + Command + Power (similar to Ctrl + Alt + Del in Windows).

If the external keyboard is not working, check:

• 🔌 Connection to another USB-Port (possibly one of the ports is damaged).
• 🔄 Reboot the keyboard: turn it off and reconnect it.
• 🖥️ Operating the keyboard on another device (to avoid its malfunction).

💡

If you don't have an external keyboard, but you have an Android smartphone, you can use it in USB-OTG mode. Connect your phone to your laptop via an OTG adapter and install the USB Keyboard app (like Remote Keyboard) to emulate the keyboard through the smartphone's touch screen.

5. Hardware discharge through the power connector (last resort)

If all the previous methods failed, you're left with a hardware reset through the power connector, which simulates battery extraction and resets all the temporary data in memory, and you only use it as a last resort, because the wrong actions can damage the motherboard.

Instructions:

1. Turn off the charger and all peripherals (mouse, keyboard, flash drives).
2. Turn over your laptop and find a small hole on the bottom lid that says RESET or CMOS (usually next to the vents). On the RedmiBook 8 Pro, it is located on a USB-C port.
3. Take a paperclip or toothpick, gently insert it into the hole and press before clicking (you need to use the micro-switch inside).
4. Wait 10-15 seconds, then plug in the charger and try turning on the laptop.

If there is no RESET hole, an alternative method is:

• 🔧 Unscrew the bottom cover of the laptop (you will need a Torx screwdriver). T5).
• 🔋 Find a battery on the motherboard CR2032 (It's responsible for keeping the settings. BIOS).
• ⏱️ Remove the battery carefully for 5-10 minutes, then set back.

⚠️ Note: Disassembling your laptop will void Xiaomi's warranty. If you're unsure of your skills, contact an authorized service center. Also, don't touch the components of the board without an antistatic bracelet - static electricity can damage the chips.

💡

Hardware reset via CMOS resets all BIOS settings to factory, including boot priority and passwords. After the procedure, you may need to reset the time, date and download parameters.

Alternative methods: from network adapter to service center

If none of these methods have worked, consider the following options:

1.Use of a docking station or hub

Some docking stations (such as the Xiaomi USB-C Hub) have their own power button that can initialize the laptop to turn on. Connect the dock to the PD-enabled USB-C port and try pressing the power delivery button.

2. Connect to another monitor

If the laptop is turned on but the screen is not working, connect it to an external monitor via HDMI or USB-C. It may be a matrix or plume problem and the system is loading normally. Once the monitor is connected, use an external keyboard to restart.

3. Contact the service center

If the power button is physically broken (for example, broke off or fell inside), it will need to be replaced. Xiaomi service center will perform this procedure in 1-2 days, and the cost of repair will be about 1,500-3000 ₽ (depending on the region).
