Hi, Mentat Tir, who told you you could connect a J680 to PC using a USB cable? You need a serial cable which is sold with the Jornada or you can buy it at eBay or similar bargain sites. Actually, be careful when unplugging this USB cable because your Jornada serial port could get damaged
Jornada 720 and following models do have USB connection but J680 and 680e doesn't. Cable terminal on the Jornada side and serial ports in docking cradle and Jornada itself can be confused
by many people with a USB connector.
And you better use Active Sync 3.8, so uninstall AS 4.5 and leave 3.8 installed.
You can get the J680 manual in
http://www.hp.com site
(I've tried just now to send you the link and could not get it, it's strange, don't know why
), so do the following
(I assume you already have the serial cable
):
1
) Connect the docking cradle to AC power
2
) Connect the serial cable as follows: the 9-pin terminal of the cable to serial port in your PC and the other terminal
(the one that looks as a USB
) to the docking cradle port.
3
) Open and run Active Sync
4
) Carefully sit the Jornada
(switched off
) onto the cradle
(you'll hear a click
). 5
) The Jornada will start on automaticallly and you`ll see a message on Active Sync dialog box saying "Connecting" and then "Connected".
6
) A dialog box in Active Sync asks you whether you want to synchronize to your PC or being just a guest
(the latter allows you only to move files, create folders, installl programs to the Jornada and so on
).
In PC go to C: and look for a folder named Handheld Device or so, double click it and there you can see the files and move them to your PC or viceversa.
(Some files will be converted whiel migrating them specially Word and Power Point.
Of course, if you have a Compact Flash card installed in the Jornada you can save your files there and use a card reader connected to your PC via USB to move the files betwen them. it's easier than using the serial cable
. I don't have a card reader yet so I use the cable. I must be careful because the little plastic thing that makes click in the cradle when putting Jornada on broke off : one day, so instead of using AC power now I use the long lasting battery
(much heavier
) to make pressure on Jornada to mantain the connection. But it works fine.
Good luck
, send me an email
(it's in this site in members section
) and I can send you the manual.

I hadn't browsed there anymore since may weeks ago ´cause I had dowloaded all of them (User guide, Short installation guide and Addendum).
