I like to watch videos before I sleep. I also like my computer to shutdown after I go to sleep. But for the last month, everyday I have awoke to find my computer had been running all night. It's kinda a resource intensive machine, with an 850watt power supply. To save on energy, and for the life of the PC, I would prefer it not run for hours when I'm not using it. In an attempt to discover the source of this problem. I ran across and article which instructed me to open CMD prompt, and type in. "powercfg -requests" . The result of which tells me that Firefox is the program that is preventing my power options from operating. So I am seeking out further help on this. I appreciate your time. __________ C:\Windows\system32>powercfg -requests DISPLAY: [PROCESS] \Device\HarddiskVolume3\Program Files (x86)\Mozilla Firefox\firefox.exe display request SYSTEM: [DRIVER] Realtek High Definition Audio (HDAUDIO\FUNC_01&VEN_10EC&DEV_1220&SUBSYS_1458A0C3&REV_1001\5&2ef4f64a&0&0001) An audio stream is currently in use.
