When my monitor goes to sleep the powere light turns white. Before I can take the monitor out of sleep mode I have to tap my keyboard and wait until the power light on the monitor turns purple, then I can start using my computer. The light was always purple until recently. Don't know what happened.
You're saying that's the way monitors are designed, but what I'm saying is it wasn't like that. The power light on my monitor was always purple. As soon as i tapped any key on my keypad my computer would open right up and all I had to do was type in my pin. Now the light on the monitor is white and when I tap the keypad I have to wait until the power light turns purple before I can type in my pin. So, that's what I'm confused about. My operating system on my Mac is Sierra V10.12.2. Does that make a difference.
OK., all that being said, if you're still telling me "that's the way it is", then I'll have to accept that.
