The power button on your ASUS Zenfone is crucial for many functions, from turning the device on and off to restarting it when it’s acting up. However, what happens when that button stops working? It can be frustrating and seem like you’re stuck with a bricked phone. Thankfully, there are several methods you can employ to restart your ASUS Zenfone even without a functioning power button. This guide will walk you through these options step-by-step, helping you get your phone back up and running.
Understanding the Problem: Why Your Power Button Might Not Work
Before diving into solutions, it’s essential to understand why your power button might be malfunctioning. Common reasons include physical damage from drops or impacts, wear and tear over time, software glitches interfering with hardware functions, or even a temporary freeze that makes the button unresponsive.
Ignoring the cause won’t solve the issue in the long run. Consider whether the button feels physically broken (stuck, loose, or unresponsive to touch) or if it’s a software problem. If it’s physical damage, professional repair might be the only permanent solution.
Restarting via Alternative Button Combinations
While the power button is the most direct way to restart, ASUS Zenfones (and Android phones in general) sometimes offer alternative button combinations that can trigger a restart or access recovery mode, from which you can restart. These methods are particularly useful when the phone is frozen.
The Volume Button and Home Button (if applicable) Approach
Some older ASUS Zenfone models (and some Android devices in general) may respond to a combination of the volume button (usually the volume up button) and the home button (if your device has a physical home button). While holding these buttons, try plugging your phone into a power source. This might trigger the device to boot into recovery mode, from where you can initiate a restart.
The success of this method depends heavily on your phone model and its specific configuration. It’s worth trying if your phone has a physical home button and the volume buttons are functional.
Utilizing the Volume Up and Volume Down Buttons Together
In some instances, holding both the volume up and volume down buttons simultaneously while plugging the phone into a charger can prompt a restart. This method is less common but worth a try if other button combinations fail. Press and hold both buttons for about 15-20 seconds while the phone is connected to a power source.
This might force the system to recognize a need for reboot or initiate a low-level reset sequence.
Leveraging the Charging Mechanism for Restart
Sometimes, simply plugging your ASUS Zenfone into a power source can trigger a restart, especially if the device is completely drained or has encountered a minor software glitch.
The “Dead Battery” Trick
If your phone’s battery is completely depleted, plugging it into a charger might automatically initiate a restart sequence. Allow the phone to charge for a few minutes (around 5-10 minutes) to ensure it has enough power to boot up. This is a common scenario, particularly when the phone has shut down unexpectedly due to low battery.
Forced Restart Through Power Fluctuations (Use with Caution)
This method is riskier and should only be used as a last resort. Rapidly plugging and unplugging the charger multiple times might sometimes trigger a restart. This works by creating power fluctuations that can disrupt the system and force it to reboot. However, be extremely cautious, as this can potentially damage your device’s battery or charging port if done excessively or improperly.
Warning: This method can be harmful and should be used sparingly and with extreme caution. We are not responsible for any damage caused by this method.
Employing Android Debug Bridge (ADB) for Remote Restart
For more technically inclined users, the Android Debug Bridge (ADB) offers a powerful way to interact with your ASUS Zenfone from a computer, including the ability to restart it even without a working power button.
Setting Up ADB on Your Computer
Before you can use ADB, you need to install it on your computer.
- Download the ADB platform tools from the official Android Developers website (search for “ADB platform tools download”).
- Extract the downloaded ZIP file to a convenient location on your computer (e.g., C:\adb on Windows).
- Add the ADB folder to your system’s PATH environment variable. This allows you to run ADB commands from any command prompt window.
Enabling USB Debugging on Your Phone (If Possible)
USB debugging needs to be enabled on your ASUS Zenfone for ADB to communicate with it. If you can access your phone’s settings, follow these steps:
- Go to “Settings” > “About phone” (or “About device”).
- Tap on “Build number” repeatedly (usually 7 times) until you see a message saying “You are now a developer!”.
- Go back to “Settings” and you will find a new option called “Developer options”.
- Enable “USB debugging”.
Note: If you cannot access your phone’s settings because it’s frozen or off, and USB debugging wasn’t previously enabled, this method will be significantly more challenging, if not impossible.
Using ADB to Restart Your Phone
- Connect your ASUS Zenfone to your computer via USB cable.
- Open a command prompt or terminal window on your computer.
- Navigate to the ADB folder (e.g.,
cd C:\adbon Windows). - Type the command
adb devicesand press Enter. This will list the connected devices. If your phone appears in the list, it means ADB is communicating with your phone. If not, ensure you have the correct USB drivers installed for your ASUS Zenfone. - Type the command
adb rebootand press Enter. This will send a reboot command to your phone, and it should restart.
Addressing Driver Issues
If your phone isn’t recognized by ADB, you likely have a driver issue. Search online for the specific USB drivers for your ASUS Zenfone model and install them on your computer. Rebooting your computer after installing the drivers might also be necessary.
Exploring Accessibility Settings for Potential Workarounds
Android offers several accessibility features that might provide alternative ways to interact with your phone, even with a malfunctioning power button. These are more useful for performing actions after the phone is on.
Scheduled Power On/Off Feature (If Enabled Previously)
Some ASUS Zenfones have a built-in scheduled power on/off feature. If you had this feature enabled before your power button stopped working, your phone might automatically turn on or off at the scheduled times. This doesn’t directly restart the phone on demand, but it can turn it on if it’s off, providing a starting point.
To check if your phone has this feature, typically you would find it under “Settings” -> “Battery” or “Power Management.” However, since the phone is likely off or unresponsive, checking this is only helpful for future prevention if you eventually get the phone restarted.
Accessibility Menu for Power Control (If Enabled Previously)
Android’s Accessibility Menu, if enabled, can provide on-screen controls for various functions, including power options.
To enable the Accessibility Menu:
- Go to “Settings” > “Accessibility” > “Accessibility Menu.”
- Toggle the switch to turn it on.
If you had already enabled this menu before the power button failed, you could potentially use it to simulate power button functions like restarting or turning off the device. The process to enable can vary a bit based on the android version and Zenfone Model.
Using Third-Party Apps (Requires the Phone to Be On)
If your ASUS Zenfone is already on, but you anticipate needing to restart it without the power button in the future, you can install third-party apps that offer restart functionality.
“Quick Reboot” and Similar Apps
Apps like “Quick Reboot” and others available on the Google Play Store provide one-tap restart options directly from your home screen or app drawer. These apps typically require root access for full functionality (including the ability to perform a full restart), but some might offer limited restart options without root. Always research the app’s permissions and reviews before installing.
Preventative Measures: Avoiding Power Button Reliance
While you’ve learned how to restart your phone without the power button, it’s wise to explore preventative measures to reduce your reliance on it in the future.

In some cases, the device will automatically power on upon detecting a charging current, effectively bypassing the need for the power button. This method relies on the phone’s automatic boot-up sequence when charging from a completely off state.
If charging doesn’t automatically turn on the phone, you might need to try a combination of pressing and holding the volume up or volume down button while simultaneously plugging in the charger. This action may trigger the phone’s bootloader menu, from which you can then navigate to the “Restart” or “Power On” option using the volume buttons and selecting with another functioning button (if available), or by waiting for the phone to eventually boot up. The exact key combination can vary slightly depending on the specific Zenfone model.
Can I use ADB (Android Debug Bridge) to restart my ASUS Zenfone without the power button?
Yes, you can leverage ADB (Android Debug Bridge) to restart your ASUS Zenfone if the power button is broken, provided that USB debugging is enabled on your device beforehand. ADB allows you to send commands to your phone from a computer, including the command to restart it. This method is particularly useful if you need to reboot into recovery mode or perform other advanced operations.
To utilize ADB, connect your Zenfone to your computer via USB. Ensure you have the necessary drivers installed for your device. Open a command prompt or terminal window on your computer and navigate to the directory where you have installed the ADB tools. Then, execute the command adb reboot. This command will instruct your phone to restart, bypassing the need for the physical power button.
Is it possible to schedule automatic restarts on my ASUS Zenfone as a workaround?
While there’s no built-in feature in the ASUS Zenfone to schedule automatic restarts directly, you can achieve this functionality through third-party apps available on the Google Play Store. These apps simulate restarts at predetermined intervals, offering a temporary workaround if your power button is malfunctioning. Be cautious when selecting an app and read reviews to ensure its reliability and safety.
These apps typically require root access to the phone for complete control over the system’s power management. Without root access, the app might have limited functionality or might not be able to perform a full restart. Therefore, carefully consider the implications of rooting your device before using such apps, as it can void your warranty and potentially introduce security risks.
What is the “Double Tap to Wake” feature on ASUS Zenfones and how does it help?
