I had them same problem. I would add that when I attached the FLIP MinoHD to my computer via its USB jack, the led on the jack blinked continuously, yet the device was not even acknowledged by windows, nor would it power on after sufficient time for a complete charge. Also, I tried the reset button hidden in the tripod socket, and called tech. serv. only to discover that repair would cost as much as a new unit!! Only worthwhile, perhaps, if you have very valuable video trapped in the device's memory. I didn't. I looked at the disassembly instructions here at ifixit.com and determined that the first chip near the usb jack (TPD12S521DBTR) was a likely bad component and ordered a couple from digikey.com for $1.79 each. When the chips arrived, I opened my MinoHD only to discover it had a substantially different design from the ifixit.com version, and the chip I ordered was not in my design!! I reassembled the dang thing, and it works fine. I can only conclude it was probably a bad connection or a bad logic state ...
