LG G5 Power Button Not Working Troubleshooting Solutions

It is still unclear if the power button failure is a malware or app problem. However, Safe Mode can help detect if the LG G5 power button issue was due to a malfunctioning app. Alternatively, you can solve the problem by performing a factory reset on the smartphone if Safe Mode was unable to correct the problem. After resetting the phone, ensure the phone is running on the latest software version from your carrier.

Turn On LG G5 Without Power Button

If your LG G5 is not responding to the power button, you can turn it on without it. If the phone is on, you can wake the phone up by connecting it to a computer, a charger or by pressing the Camera button if the phone has one.
If the phone is off already, it can be hard to turn it on without the power button. In some limited models, connecting the phone to a computer or long pressing the volume buttons will turn on the phone. If USB debugging was enabled before the phone was off, you might attempt to install ADB on your computer and use command prompt to turn on the device.
