Hi, I want to thank you for this great place to come to and find help. My problem is that when I turn my computer off manually the screen goes off and will not come back on. The button turns amber and then it shuts off. The only way to get it back on is to unplug it turn the computer back on and then re-plug the screen. It is a real pain, and this happens regardless of what computer I use. Is there anything that you can think of that would cause this? There are 4 buttons on the Dell flat screen the on button one with a plus a minus and I don;'t know what the other button is for. Thank you for your time. :sad:
