Off topic, but I felt it belonged in this thread as it was my inspiration and this is probably the thread anyone else in my position would land in. Two weeks ago I tried unsucessfully to wire in an old laptop PS to the dock, freeing up the included power supply cable so I could charge the unit at home and the office. Initially it didn't work (dock lit up, but refused to charge), but it hadn't occured to me that the cable would have three seperate V+ supply lines. I'd expected they were using the three pins in the dock connector to simply carry the current. Grounds are all tied together inside the dock as well for those who wonder. After some tentitive testing and a leap of faith, I wired all three pins on the board in the dock to an old IBM supply (17.5v) which lit up the dock. Unfortunatly, the slate would still refuse to charge. I then swapped in an old 19v supply from another manufacturer (eurocom for those who might remeber), and the slate charges fine. LED on front goes orange during charging, and white when complete. It's a monster supply from days of yore' and seems very stable. No guarantee this isn't going explode in the future, but for those like me who've been on back order for a replacement brick for 2.5 months now (next week my arse), it's an intrim solution. I think I might order another dock instead. Thanks Werewolf!
