Win8.1 boot into the system without boot music reason and solution

Cause analysis:
Win8.1 system shutdown action is performed by deep sleep, not completely shut down, set the check box in the setting In the state of playing the Windows startup sound & rdquo;, the "fast start" function is not canceled, so the computer performs the wake-up action from the deep sleep instead of the shutdown and restart, so the booting sound cannot be heard.
Solution:
1. On the system desktop, left click on the system in the lower right corner to 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 be changed, first click “ change the currently unavailable settings ”;
4, in the following interface, 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”.
Win8.1 system default is fast start, and there is no real complete shutdown or boot, so every time the user enters the system, it is only a wake-up in the sleep state, not really boot.
