Einleitung

Not getting the speed and memory out of your tablet that you would like? Is there a bad connection between the motherboard and the digitizer, which may cause a black screen? If so, use this guide to replace the motherboard on the device. Be sure not to lose the screws once you remove the motherboard. There are a total of three screws that fix the motherboard onto the digitizer.

    • Before disassembling your device, make sure that the power is completely turned off.

    • Use the plastic opening tool to release the clips holding the rear panel of the device onto the front section.

    • The clips may take some pressure before releasing.

    • Continue around the entire device until all of the clips have been released.

    • Use a spudger to carefully free the speaker from it's housing on the back panel.

    • Place the spudger between the speaker and the rear panel. Use a prying motion to remove the component.

    • Be careful not to apply an over amount of force. If care is not taken, the speaker could break under the pressure.

    • Insert the flat side of the standard spudger underneath the battery and use a prying action to loosen the glue holding it to the digitizer.

    • Do this all around the battery until it comes off.

    • The glue is strong, so some force may be required. However, be careful not to apply so much pressure that the battery bends or breaks.

    • At this point, do not attempt to fully remove the battery, since it is still connected to the motherboard.

    • Use the Portable Soldering Iron tool to heat the leads coming from the battery to the motherboard, thereby breaking the connection.

    • For help on soldering, refer to the iFixit "How To Solder and Desolder Connections" technique guide as necessary.

    • Once heated, use tweezers to pull the wires free from their connections.

    • To ease reassembly, take note of which wire went to the positive and negative terminals.

    • Use the Portable Soldering Iron tool to heat the lead coming from the Wi-Fi antenna to the logic board, thereby breaking the connection.

    • For help on soldering, refer to the iFixit "How To Solder and Desolder Connections" technique guide as necessary.

    • Once heated, use tweezers to pull the wire free from its connection.

    • The camera module is located in the upper-right corner of the tablet.

    • Loosen the edges of the black tape covering the camera using the heavy-duty spudger.

    • Use the freed edges of the tape to gently remove the camera assembly from its plastic housing.

    • The camera assembly will still be connected to the rest of the device via a ribbon cable. Take care so as not to tear this connection.

    • Use tweezers to lift the cover off the top of the camera's ZIF adapter.

    • When reassembling the device, be sure to fully secure the ribbon cable from the camera back into the ZIF adapter.

    • Pull the assembly away from the motherboard with a set of tweezers to prepare for desoldering.
