Windows 10 computer turns itself ON
I have a new-to-me refurbished (from Amazon) Dell Optiplex 9020 desktop with Windows 10. Attached to it are a Dell SE2719H monitor, Logitech Trackball, Brother Laser Printer, and Linksys Router. Everything seems to work fine, except ...
In the evening, I turn it OFF at START>Power>Shut Off; the light at the ON/OFF power button at the front top left of the computer itself goes off (disappears). I do not turn off the monitor; when the computer is turned off, the screen displays "No VGA device is detected", and goes black.
Then, in the morning, the computer is ON. At some point during the night, the computer turns itself back on. How, why, does it do that? (I assume ... correctly? ... a monitor does not have the capability to turn a computer itself on.)
A Google search yielded a suggestion that it may be the mouse (which in my case is the Logitech Trackball). So, as suggested there, at START>Device Manager>Mice and other pointing devices>HID compliant mouse>Power management, I unchecked "Allow this device to wake the computer" (even though I don't know what an "HID compliant mouse" is). That evening, I turned the computer off at START>Power>Shut Off; in the morning, it was ON.
Other than unplugging the computer from the wall in the evening, I don't know what to do. I will appreciate any thoughts!
