Good news first – my Palm Tungsten C is fine and happily running with replaced batteries. Bad news, consider pretty carefully if you really want to do it yourself. I read that the maintenance people could charge you 170$ for the operation, that could cost no more than 40€ if you do it yourself. But … doing it by yourself is risky, you could send the little gizmo in the grey silicon pastures of heaven.
Ok, you take the risk, here’s the instructions. Have a look at yesterday post for a link to some good and detailed pictures of the operation).
With your trusty Torx screwdriver unscrew all the four screws on the back of the PDA. The back is kept in place by two clips about at the middle one on the left and one on the right side. There is nothing to do but to gently pull the back inserting your nails in the sides.
Now the back is removed, take a deep breath and astonished watch for a while what could be stone dead in a matter of seconds.
You see a small board piggy-back’ed on a larger one, fixed with two (standard) screws and with a single black wire going upward. That board is the wi-fi module. Unscrew the two screws and then pull gently the wi-fi module away from the main board. It won’t come easily because there is a connector below. Be gentle and firm and stay relaxed.
Now the main board. This flat bastard is hold by four little plastic tags (two per sides) and has the keyboard connector below (very similar to the one from which you unplugged the wi-fi module). Moreover the audio plug will try to stay where it is (upper right) keeping together the rest of the system. First use a pin or something like that to unplug the battery connector on the middle left edge. Then lift the board so that the board is above the four tags, then unplug the keyboard connector and eventually slide the board toward the lower edge being careful about the audio plug.
And now you can see the batteries. Don’t hold your breath, they won’t jump out of their place… they have been glued (!) to the tin sheet below. Start from a side and use a screwdriver as a lever to gently (again) pull the batteries out.
Perfect you are halfway, replace the batteries paying attention to keep the right orientation of the original pack. The put back the main board. Slide it in first with the audio plug (maybe you have to lift the screw hole at the top), move it below the tags and then push the bottom to make the connection to the keyboard.
Connect the batteries, this require some skill since the connector is to be … invited in the right place rather than put, since there is not space for your fingers here.
Put the wi-fi module back, press it to connect and then screw it in place.
Eventually put the back cover, verify that the two clips hold it and eventually screw the 4 screws.
Done… Count up to three and connect it to the power. Mine worked at first attempt, I had just to synchronize it to have it in the same state it was before replacing the batteries. I lost a kg in the process.
