Hi,
contacted the german customer service *), got a RMA, sent in the SurfPad, got it back repaired (new motherboard) within a week. 0.00 costs.
Awesome!
Since "she-that-has-to-be-obeyed" looks greedily at my SurfPad more and more, I'll order a SurfPad 4 as soon as available ;-)
Have fun, JG
*) Very friendly & helpful ladies there, even if I have no invoice anymore, they asked for serial number to check if warranty was possible. Was possible!
