There was a smoke cloud in about 1 second. I disconnected the battery immediately, but the damage was done. It now doesn't see the battery, but works fine with the usb connector only. After a quick inspection ,I saw that a component on the board is fried. Its called "U7". A 5 PIn chip. I suspect its a chip regulator. Does anyone know what its value is, or if possible a work around, or know where I can get a schematic. (with values) regards, HenryJP[:I] [/quote]    Insert an Image File Check here to include your profile signature.
