Mine plainly came back to good working order on its own. Guys, it's so weird! I sent mine to post-warranty and they returned it saying that the fluid marker was activated and that they could only replace the whole Dock board for around 1800 euros. I told them to return it to me because other than maybe vapour or condensation there was no fluid contact with the laptop and that their solution is absurd! I changed my laptop from SB2 to another because I couldn't work like that (i.e. with an external keyboard) and after a year on the shelf, when a friend asked if he could use it as a desktop replacement at home, we just figured it worked just as before (this after all the updates - many - were made)… so, my SB2 works great now!
