I recently purchased from Dell online a new computer and monitor. For the first week it has worked flawlessy. However yesterday after a long break I could not rouse the monitor out of sleep mode no matter what I did.
First -- I just wiggled my mouse as I have always done — Nothing!
Second-- I pressed keys on the keyboard — Nothing!
Third -- I pressed the power button which was still illuminated with zero response.
Fourth -- I rebooted the computer and still the screen was black.
Fifth -- I unplugged the monitor power cord at the monitor. That worked!! I saw my "boot" screen and then signed in.
Today it did it again, and I tried the same five steps above. I unplugged it again. This time the Dell logo appeared then the monitor power shut off (monitor power button went dark) I pressed it and it came on and I'm working fine now.
Now I don't know whether or not to allow it to sleep or just turn everything off. And I am certainly not too keen on unplugging my monitor every time I want to use it!!
By the way, I am using Windows 10 installed by Dell on my PC.
I will appreciated any helpful ideas to cure the Rip Van Winkle syndrome.
