Dell LCD displays don't sleep when disconnected

Dell LCD displays don't sleep when disconnected

Many of my co-workers use laptops. When they disconnect them and take them home, the external Dell LCD displays (1907FP, 1908FP, 2007WFP, etc.) stay on, with a graphic indicating that there is no source connected to the monitors. The problem is, the displays never sleep, therefore wasting power (~40W for a 19" 5:4 panel). Over several people and many hours, this adds up.

"Maybe you can consider installing smart power strips on the work places. If the worker goes home and packs his power adapter from the laptop, the main power using device is disconnected and thus the smart strip shuts down all the other connected devices, like the monitor, wireless mouse and cellphone charger.

This not only saves money, but it lengthens the life of the backlight with a factor 4 if you consider 40 working hours in a week of 168 hours!"

"Most Dell monitors that I know, automatically enter power save mode after 1-2 minutes of no-signal.

Have you contacted Dell Support?"
