I have recently bought a DN2820FYKH and it works great, except for that it powers on automatically sometimes.
For instance, I shut it down through my operating system and it shuts down. Moments later (don't me ask how long as I notice it by mistake) it's turned on again. I unplug the power cord and plug it back in 4 hours later and it still turns back on later (not instantly). I have also tried shutting it off by holding the power button down and got the same results.
I can say right away that the BIOS is not upgraded (11 BIOS updates behind), Intel's instructions say that you should only upgrade if you know that the update will solve a particular issue (is that correct? First time I've heard that one). But in any case, I am curious to find out if this is a known issue/bug or if anyone have a hunch that setting x in the bios is/can be the cause of this. Any ideas?
