Introduction

The motherboard controls all of the processes of the device and if it is faulty must be replaced otherwise the device will not operate.

    • Before removing the battery, make sure the device is powered off

    • Use a plastic opening tool to pry open the back cover of the tablet.

    • The second picture shows the tablet with the back removed.

    Removing the cover was a struggle (for me, a newbie). Took 10 minutes+. I don’t have a plastic tool and the small screwdriver left marks. But a non-functioning tablet has zero value so …

    • Remove the tape that secures the ribbon cable.

    • Use precision tweezers if the tape cannot be removed by hand.

    C’est inutile !

    FWIW, my lenovo looks a bit different. I purchased it in the spring of 2019. The battery specs reveal differences too. No biggie…

    Frank Harvey -

    The unit shown in this fixit session has a 26.6 wh battery while my April 2019 tablet claims only 18.7 wh. My unit’s battery is nearly square and is not held down by the screwed, metal ring shown in your photos.

    • Handle ribbon cables with care so it does not rip or tear.

    • Carefully remove the ribbon cable from the power button connector.

    • To remove the cable, push the clamp on the connector up and pull gently.

    The clamp is on the opposite side of where the cable inserts. It is hinged to pull up vertically to the right toward the cable.

    The discussed cable doesn’t even exist on my April 2019 Lenovo. Good thing b/c a later comment indicated problems replacing the left side of that cable.

    • Unscrew the hidden 2mm screw using the Phillips #000 drill bit.

    • Remove the second piece of tape from the other ribbon cable connected to the battery.

    Inutile et risqué !

    • Remove the screws securing the battery connector cover.

    • Two 2mm Phillips screws.

  8. 4VJfQ62xxVTTZAbn

    • Once the screws are removed, remove the metal cover shown.

  9. DgDfvvQjtXY5OlgH

    • Gently remove the following:

    • Disconnect the battery ribbon cable.

    It pulls up vertically and not horizontally.

    Carl Bezanson -

    On my April 2019 model (TB-x104F), there’s no screwed, metal ring. The battery is, instead lightly glued to the plastic base. There are 2 ‘ramps’ in the plastic on what would be the right side of your photo. I moved the unit to my outdoor barbeque in case mangling the lithium battery started a fire. I pushed my largest, flat blade screwdriver down each ramp, taking turns. Gradually I lifted the battery out. It looks curved and probably broken. I took the tablet inside and left the battery in the bbq.

this tablet does not support any android update anymore and has historical issues with wifi. Can any newer motherboard be installed with the same screen and battery and case? some sort of HW upgrade last trial before it ends in the bin...
