Having the same issue. Haven't been able to figure out what triggers it. This is my second U2711 with the problem. Support wouldn't elaborate what the problem is and that I should simply exchange it. It doesn't flash all of the time. The monitor seems to be functioning normally otherwise.
I had the same issue and was able to control it after determining it to be a local environmental / electrical EMF interference problem.
The menu buttons on your monitor are capacitive sensing in nature. That means they are also probably sensitive to the presence of fields of electric charge. I see it seems normal for the menu button to light up when you put your hand or finger near it (see this video) Notice at 0:03 seconds as the menu button lights up in the proximity of the finger. Now if this button senses the capacitance of a finger, it also will sense the capacitance of other objects in it's proximity such as powered speakers, electrical cables, printers, etc. I had the random menu light blinking issue until I figured out I that the power cord, to my laptop, running across my desk was too close to the menu button. A quick repositioning of the cable away from the button solved the problem. As well, replacing the cord near it's original location recreated the problem.
Dell tech support has NO information on this. In fact they could not even tell me if it was normal for the buttons to light up as they do. I assume they have replaced quite a few monitors because of this non-problem. The only thing I cannot testify to may be that some of the menu buttons, on some monitors, are too sensitive to EMF.
I suggest moving electrically powered objects away from the proximity of the monitor's menu button or trying your monitor in a new location (as free of emf as possible) to see if it changes the button behavior.
Hope this helps everyone who has posted about this. This should end up saving Dell money as well.
Well i have the same monitor and the same error. I have the monitor without any powered object close...
i purchased this monitor in 2012, but since 2014 with the led blinking problem. Now are out of warranty, someone know if is possible to fix that led blinking power button? someone from Dell?
Im very dissapointed with the dell quality monitor, my last 3 monitors was dell and after 2 years all was fault :/

Here is what I believe to be the correct answer:
