Understanding the Problem

When the power key on your Xiaomi Mi 11 Lite is not working, it can prevent you from turning the device on or off, putting it to sleep, or waking it up from sleep mode. This can be caused by a variety of factors, including software glitches, physical damage, or hardware issues. By identifying the underlying cause of the problem, you can take the necessary steps to fix it and restore functionality to your device.

Troubleshooting Steps

1. Restart Your Device

The first step in troubleshooting any software-related issue is to restart your device. Press and hold the volume down button and the power button simultaneously for about 10 seconds until the device restarts. This can help reset any software glitches that may be causing the power key not to respond.

2. Check for Software Updates

Ensure that your Xiaomi Mi 11 Lite is running the latest version of MIUI and Android. Go to Settings > About phone > System update to check for any available updates. If an update is available, download and install it, as it may contain bug fixes or patches that address the power key issue.

3. Perform a Factory Reset

If software updates do not resolve the issue, you may need to perform a factory reset to restore your device to its original settings. Note that this will erase all data on your device, so be sure to back up any important information before proceeding. Go to Settings > System > Reset > Factory data reset to initiate the process.

4. Check for Physical Damage

Inspect the power key on your Xiaomi Mi 11 Lite for any signs of physical damage, such as cracks, dents, or debris. Clean the power key and the surrounding area with compressed air or a soft brush to remove any dirt or debris that may be obstructing the key's movement.

5. Test in Safe Mode

Boot your Xiaomi Mi 11 Lite into safe mode to determine if the power key issue is being caused by a third-party app. Press and hold the power button until the power off menu appears, then press and hold the "Power off" option until "Reboot to safe mode" appears. Tap "OK" to reboot into safe mode. If the power key works normally in safe mode, a third-party app may be causing the issue. Uninstall recently downloaded apps to see if the problem resolves.

6. Contact Customer Support

If none of the above steps resolve the issue and your Xiaomi Mi 11 Lite is still under warranty, contact Xiaomi customer support or visit an authorized service center for further assistance. A technician can diagnose the problem and recommend repair options, such as replacing the power button or repairing any internal components.


A malfunctioning power key on the Xiaomi Mi 11 Lite can be a frustrating issue, but with the troubleshooting steps outlined in this guide, you can identify the cause of the problem and take appropriate action to resolve it. Whether the issue is software-related or due to physical damage, following these steps can help you restore functionality to your device and continue enjoying all the features it has to offer. If the problem persists, don't hesitate to seek assistance from Xiaomi customer support or a qualified technician for further assistance.
