Connected screen and ethernet dropping out / blinking Dell M3800

OK, I have run through those items.

I have changed the power settings as described.

I have updated to the latest USB driver, even though it is not the one that Dell recommend on their website.

I will give it a go over the next day or so to see how it pans out.

Well it is on the blink again.

The only thing I have not tried on the list is plugging into an external USB hub as I don't have one.

Strangely the wireless keyboard and mouse plugged into the unit still work on the other screen when it is blinking.

OK, now all solved.

Dell came and replaced the motherboard on the laptop and I haven't had any issues for the past week or so.
