Well then, this is my first negative post; as such I welcome myself to the club of disgruntled Surface users. Just joking since in fact my issue has to do with Microsoft's docking station and not with the Surface directly: I bought this (very expensive) dock yesterday, plugged it and connected my Samsung external 23" monitor and my 4tb external disk to it. First issue: The monitor would not be recognized and wouldn't turn on. Upon googling around I eventually found and installed a couple of registry and firmware updates, to no avail. Upon googling some more I found the original solution of a user which had just plugged the dock's magnetic connector to the Surface so that the part bearing the led would be upside down. I tried that and bingo! The monitor showed up and I was able to extend the Surface desktop onto it. Problem solved? No. Second issue: After a short while my wifi connection dropped. I noticed immediately since I have a very good router with a rock-solid connection. I tried to turn wifi on and off, restart the Surface, disconnect and reconnect but nothing would do it. Then the idea struck me. I unplugged the dock and wifi connected instantly. I plugged the magnetic connector back on the Surface, and 30 seconds later wifi dropped again. I tried to look around for solutions but could not find any, since this apparently is a problem which Microsoft still has to find a workaround for. Third issue: I decided to skip the external monitor thing and keep the dock as a battery charger and Usb hub. Surprise, surprise. The wifi disconnected again after I plugged the external disk on the dock.... Fourth issue: I unplugged the external disk and started using the dock as a (very expensive) battery charger. What else could happen? Well now I have a reply. When the Surface is plugged to the standard charger light activities such as web browsing, email, word processing never engage the cooling fan. Trying to charge the Surface with the dock causes the fan to kick in as soon as more than two apps are open at the same time. In my case it was Onenote and Opera (Onenote idling in background and doing some light surfing with Opera). Not only was the fan wheeling away like crazy, but it was much louder than when I am playing demanding games such as Skyrim, AC or Tomb Raider... Long story short: I unplugged the whole thing, put it back in its box and on Monday I'll file for refund. Useless to say that as soon as I plugged the standard charger the Surface went back to its usual silent self... Lesson learnt: "Less is more".
