    • The back panel must be removed in order to proceed. Slide the cover so that it is fully extended.

    • The arrows in the picture indicate two small holes located at the top of the device. Insert a paper clip or a tack simultaneously into each of these holes and moderately push downward.

    • The springs will give as pressure is exerted. Once you feel this take place, pull down the cover with the paper clip/tack while continuing to push downward. This will release the back cover.

    • Now the buttons and sliding tray will be connected to the main body only by an orange cable.

    • Disconnect the cable from the main body of the device by pulling upward.

    • Set aside the buttons and slide tray, making sure the orange cable is with it.

    • The arrows indicate two small screws. Using a Phillips head screwdriver, remove them.

    • To open the device, the sides must be (with moderate force) pried apart using a prying tool as seen in the picture.

    • Both sides must be separated from one another.

    • Tip: The right side may be slightly more difficult. It will be easiest to begin on the left.

    • Beginning with the left side, gently pry at the division of the face plates until they separate from one another.

    • Repeat this process on the other side of the device.

    • Hint: There will be pressure points along the side (as seen in the picture). Exerting pressure in these points will allow the sides to separate more easily.

    • Remove the face plate and set aside. This will leave the core of the device in front of you.

    • Reminder: The core of the device will be connected by various cables. Gently lift the screen and mother board (as in picture).

    • As labeled in the picture, the orange screen cable will connect on the lower right side of the motherboard.

    • Disconnect the cable by pulling it upward from the motherboard connection. Depending on your device, it may require little to moderate force.

    • Carefully remove your screen.

    • The battery connects to the motherboard (as seen in picture) by red and black cables.

    • Remember: Be gentle when disconnecting. The wires will be tightly fitted; however, it is very important the connection is not broken in the port.

    • Gently pull out battery wire connection.

    • At this step the Motherboard control panel will be completely disconnected from your Tungsten T3 Device.

    • Replace the old control panel with the new Motherboard.

    • The new Motherboard reconnects to the battery through the same connection as shown in picture.

    • Once connected place the new Motherboard control panel.

    • Next, the screen must be reconnected to the motherboard.

    • Connect the new orange cable into the same location as the previous screen. (Location noted in picture by arrow). Make sure the cable is placed facing downward on the connection.

    • Lower the motherboard into place. Make sure to keep the back facing downward. Hint: This will be the side where all cables are connected.

    • Gently lay the screen on the core of the device.

    • As seen in figure one, the core and screen are now in tact.

    • Lay the face plate on device. It must be snapped into place.

    • Hint: when attaching the tray to the main device, the cable must be in the position as seen in the left figure.

    • Hint: On each side, the prongs must be adjusted so that they fit into their respective slots.

    • To reconnect the sliding tray and buttons, lay the device on its face.

    • Reminder: The orange button cable must be raised above sliding tray and connected to its respective port (as seen in picture).

    • To reconnect the sliding track, align the hooks and tracks (noted in picture).

    • Push the hooks into the tracks and slide the tray upward. This should lock the hooks in place.

    • To ensure that it has been connected properly, slide up and down.

    • Install the screws on both sides of device as seen in the picture.

    • Here is your repaired Tungsten T3 Palm Pilot. Enjoy!
