I have a third party AC-Adapter myself (from Speedlink, offically licensed by Nintendo), however it only works in mobilie mode, not when docked. If I use it docked, there's a beep sound and a message on the tablet that I don't use the original AC-Adapter and therefore it doesn't work. I got interested in the topic and did an internet research and the mutual conclusion was that this message will appear for virtually all non-orginal AC Adapters and that for the time being, only the original one should be used in dock mode.
