Is the back light supposed to stay on when the monitor goes to sleep mode?

Backlight goes off after a few seconds and power light goes from green to yellow on my Optiquest Q9 monitor. Is the backlight supposed to stay on in the sleep mode?

That sounds about right some monitors or TV's won't fully power down until the power button is pushed. I see that monitor has a bunch of problems and it's 8MS. If possible return and get something else.
