My working device looks the same - what specific problem are you having and did you already perform the regedit?

i have to push on the screen from top to get it connected and i then hear the windows plug in sound ... If i remove my hands amd do any move then it gets unplugged . No i didnt do the regedit but is this the same problem ? How will the regedite solve this docking issue which gets solved by pushing on the tablet towards the keyboard ?

But the strange thing is that batter is always showing the secondry battery of the keyboard which means that it is aware of the keyboard and connected to it but for some reason the keypad or the mouse won't work unless I push on the screen... Very strange !! Any explanation ?

OK, this is a different issue then.   Sounds like some of the pins are making contact and others are not.   Since mine looks identical to yours and works fine, the problem is potentially on the tablet side.   Probably need to get support to send you another tablet and a dock and capture yours for failure analysis to find out what is going on.     Please friend me and then send me your service tag, full name, address, email and phone and I'll get this taken care of for you as soon as possible.   This will allow me to do a special capture on your equipment too.

Thanks.

Thanks Brian for your help , really appreciated

I did confirm that the pins on the dock are intentionally different lengths.   This is by design per our electrical engineers.

I dont understand why Dell people are using this community page, always if i am looking for an issue and find some similiar post, the Dell employee asking for private chat. This is really not helpful, you should at least let the community know, did you solve the issue and how did you solve it.

I have same problem. It's a major inconvenience as I need to unplug & plug back whenever it disconnects. The onscreen "keyboard" pops up everytime it disconnect, so there's an indication. What kind of regedit I should do?

@anto2023​ Exactly the same problem here - it stops responding. I disattach and reattach and then it works. I'm not convinced it's the pins, as it happens without moving it

I have the same issue with Dell Latitude 7320 Travel keyboard. The problem started just after four months after purchase. The travel keyboard disconnected in an angled position but laid flat; it connected. But the problem worsened over the next month, and it was not detected in any position. I had a chat with DELL customer support, and after a month of deliberation, I got my travel keyboard replaced with a new one. My device was under warranty, so I got a no-cost replacement. Then it worked for one year without a problem, but for the last two weeks, this one also started to show strange problems. The touchpad is not detecting in a laid down position. If angled, the touchpad is detecting, but the keys are not detecting. 

I think the DELL travel keyboard (detachable) has a severe technical problem. Their engineers should fix this issue; otherwise, it's a shame such a nice tablet comes with such a faulty keyboard. Sad.
