Windows 10: "Turn off display" function no longer work, laptop goes into sleep mode instead.

Hi, I've just received back my notebook from Repair and was told that the motherboard was changed. I brought it back to test, and so I went to reset the PC via the OS itself I verified with one of the staff and he told me it was okay to do so. I proceeded to leave it on to download overnight until I realize the download did not progress as the notebook had went into sleep mode. I went on to the "power & sleep" settings and changed the sleep to "Never", and screen to "1 minute" to verify if the display off function is working. After a minute, the notebook did not turn off the display like it should, but it went into sleep mode instead.I have also tried using the hotkeys "Fn + F7" to turn my display off, but it still goes into sleep mode. When I go to the power settings, I also noticed that "Choose when to turn off the display" is missing after comparing to my old laptop which had the function working in good condition Please see attached. What could be the problem?

Display & computer sleep functions don't work with Windows 10, Build 1607

This is a desktop PC. After the Anniversary Update for Windows 10 (Build 1607) was downloaded, the sleep timer functions in Power Options, Balanced, no longer work. In Advanced Options, I have the following setttings:

• Turn off display after 5 minutes,
• Turn off hard drive after 20 minutes,
• PC goes to sleep after 30 minutes, and
• For Multimedia, I have selected "Allow computer to sleep" when sharing media.

With these settings, the display does not turn off and the desktop does not go into sleep mode. The display turns off, but then immediately comes back on. HELP!!!

 

Windows 10 Sleep Mode no longer working

I upgraded to Windows 10 with no issues. After about a week, sleep mode stopped working. It works fine if I force it into sleep mode by selecting Power...Sleep. But, it will no longer go into sleep on it's own once the specified time interval has elapsed.
I tried a couple of suggestions offered on this subject:

Under advanced settings.....Multimedia.... I set "Sharing Media" to "Allow to sleep".

Under sleep I enabled "Hybrid Sleep".

Neither of the above had any affect. Are there any other suggestions? Perhaps there is a way of determining which function is causing the laptop to NOT enter sleep mode?

Thanks.
