I bought my tf700t with tf201 dock second hand some 2 months ago. Everything worked perfectly up until 2 weeks ago. The previous owner had the thing rooted (build-number: TF700 CROMi-Xenogenesis 5.2.2- WW DEODEX). There are lots of people on the internet with the same kind of problems on unrooted tf700's so I don't expect it to be a problem with rooting.

What happens?
- The connection between dock and tablet seems to get lost, found again, get lost again etc. within minutes.
- I have a SD-card fitted in the dock and on the bottom of the screen I get messages that tell me he has found a SD-card. Then apparently it loses it again because a few minutes later the same message pops up again and again etc.
- In the beginning (and according to other people on the web still continuing) the tablet would only recognize the dock when charging. Without being plugged in it wouldn't be recognized at all. I opened up the dock and sprayed some contactspray where the cables come out of the hinge and want to connect to the small cable plugs on the dock, That seems to at least have worked to a certain extent, tablet and dock see each other. It says the keyboard should be used but then most keys won't work nor will the trackpad. Only the top row of keys keep functioning (except only the key in the top left corner (that flips a page backwards). But then again, sometimes you can use the keyboard on the dock for a while and then it's stops again (except for the top row of keys. They always work.)
- If I charge my dock to the max and then connect it with the screen most of the time it tells you that the battery of the dock is drained. Sometimes wiggling te tablet in it's slot brings back the battery to life.

Does anybody have a (possible) solution for these problems? I would be so grateful and so would a bunch of pitiful people roaming the back alleys of the internet in the hope of salvation.
One more thing. Several complainers have swiched dock and tablets and the problem seems to be with tablet. If the tablet is ok, then you fit any keyboard. If the tablet is dodgy it won't connect properly with any dock. At least that's what I hear.

Is there anybody with the brilliant solution or a hint at least? I started writing my bestseller on this thing, but like this it's going back to the study again in stead of to a nice terrace in the sun with drinks available.

Thanks in advance for all your trouble.

It looks like the problem is solved. I took the hinge apart, tightened all screws and bolts and put it back together. That seemed to do it .

Just so people don't have to look any further, here's how you take the hinge apart:

- Take out the 2 bolts on the outside of the hinge.
- On the inside of the hinge, on 'the bottom' are 3 pieces of plastic strip or adhesive tape (one approx. 12 cm long on the left side, one approx. 4 cm on the right side and on very small piece in between of 0.5 cm). Using tweezers and/or a scalpel-like knife, carefully peel away the longest strip of plastic working from the outside inwards. You will find three screws within the first 5 cm or so. Take them out. Stop peeling, leave the plastic strip around the data connector attached and start on the other end of this plastic strip, working from right to left. You'll find a screw immediately. Take it out, leave the rest of the strip attached. The 5th screw you'll find underneath the outer end of the 4 cm strip on the right side of the hinge.
- Now you can split the hinge in 2 parts. If necessary, use a small screwdriver at the outer ends to carefully wedge the hinge apart.
- In the part that's still connected to the dock you'll find 4 screws. The outer 2 have a tendency to become loose. Tightening them 'repaired' my dock.
