The situation where a Windows 11 PC goes to standby mode automatically within 10 minutes of being connected to a mobile device via USB is not a normal behavior. This issue can be frustrating, especially when you need to keep your PC awake for extended periods. In this article, we will discuss the possible reasons for this issue and provide some solutions.
Understanding the Issue
When you connect your mobile device to your Windows 11 PC via USB, the PC may enter standby mode after a short period of inactivity. This behavior is not expected, as standby mode is typically activated when there is no user activity and the PC is not connected to a power source. However, in this case, the PC goes to standby mode even when it is connected to a power source and the user is actively using the mobile device.
Possible Causes
There are several possible reasons for this issue:
- USB Selective Suspend: This is a power-saving feature that allows devices to enter a low-power state when they are not in use. When a USB device is connected, Windows may enable this feature, causing the PC to enter standby mode.
- Mobile Device Drivers: Faulty or outdated drivers for your mobile device can cause the PC to enter standby mode automatically.
- Power Settings: The power settings on your PC or mobile device may be configured to cause the PC to enter standby mode after a short period of inactivity.
