Question about Apple Time Capsule 2TB

Had the same problem. googled and browsed apple forums. Telephone support then helped me. If you still have warranty, I would exchange it because maybe the power supply overheats (sign of age) BUT the easiest thing to do is to open the black cover at the bottom (see youtube tutorials) and blow out the dust really well - if you haven't done that yet. If that doesn't help and the warranty has expired, go to the apple store. They will also try to blow out the dust, otherwise the repair will cost about 50Fr. For me, removing the cover and just blowing into it with my mouth has already helped - everything is as good as new :-)
