Lenovo notebook Win8.1 system can not start the camera how to do?

Analysis of the cause:

The shutdown action of Win8.1 system is performed by deep sleep instead of full shutdown. In the state of setting "Play Windows startup sound" in the setting , does not cancel the "Enable Quick Start" function, so the computer performs a wake-up action from deep sleep instead of shutting down and restarting, so the boot sound cannot be heard.

Solution:

1. On the system desktop, left click on the system in the lower right corner and bring the “Battery” icon. The following interface appears. Select More “Power Options”;

2, pop-up "power options" interface, as shown below, click <; select the power button function & rdquo;;

3, in the pop-up interface, found that some options can not Change, first click “change the currently unavailable settings”;

4, in the following interface, the previously unselectable options can be changed, you can see the "Enable Quick Start (Recommended)" option (The system is enabled by default), please enable “ enable quick start & ldquo; uncheck and “ save changes & rdquo;.

The default of Win8.1 system is quick start, and there is no real shutdown or booting. Therefore, every time the user enters the system, it is only a wake-up in the sleep state, not really booting.
