Win8.1 boot into the system does not have boot music reason and solution

Unable to start camera reason analysis:

The shutdown action of Win8.1 system is performed by deep sleep instead of full shutdown. In the setting, check “Play Windows startup sound”. In the state, the "fast start" function is not canceled, so the computer performs a wake-up action from deep sleep instead of shutting down and restarting, so the boot sound cannot be heard.

Unable to start camera solution:

1. Click on the system's desktop and bring the “Battery” icon in the lower right corner of the system. 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, the options that could not be selected before can be changed, you can see the "Enable Quick Start (Recommended)" option (the system is enabled by default) ), please “ enable quick start & rdquo; uncheck, and “ save changes & rdquo;.

The above is the introduction of Win8.1 boot into the system without the boot music and the solution, Win8.1 system default is a quick start, and there is no real complete shutdown or boot, so the user The time is only a wake-up in the sleep state when booting into the system, not really booting.
