I don't know if this is a fairly new development, since I haven't noticed it since before this week. However, once Steam has been launched, it passes by the minute mark without turning the screen off.

iTunes, Speedfan, and other have no effect on the screen turning off. You are just putting the display to sleep. I set the timer to 1 minute, and did some testing. Locking your display screen will protect the information stored on or. I wasn't sure what could be the problem, but it hit me that I launch a select few programs myself on login (Steam, iTunes, Speedfan, etc.).

off sleep mode on your laptop or desktop computer with Windows 10/8.1/8/7.

Select them one at a time and press the enter key to attempt a system restart. We can turn off sleep mode on computer to make computer display not sleep. On the Windows Advanced Boot Option screen, select one or more of the following options. If computer does not start into Windows, turn on the power and press the f8 key. Usually, it would work for a day or two, and then stop turning the screen off. Use Windows Advanced Boot Options to start computer. I've noticed the past few days that my computer isn't turning the screen off after the 15 minute mark, which I've set in Power Management through the control panel. So this is an odd issue, but hopefully I've got the right place for it.
