    • 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.

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

    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.

    • Gently remove the following:

    • Disconnect the battery ribbon cable.

    It pulls up vertically and not horizontally.

    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.

In my personal opinion, this guide have a bunch of steps that aren't necessary. I just replaced a cracked one. And I just removed the battery for security purposes since I was going to use heat. But you don't have to remove the mother board or anything else, just disconnect the digitizer flex and then start prying on front. That's it.

Is that black tape important? I wasn't lucky and it was torn.

How do you calibrate the digitizer afterwards?

Step 11 talks about using a Phillips 000 drill bit, rather than screwdriver, to remove the screws.

If your TB2 is more that three years old, the adhesive securing the digitizer to the plastic body is probably dry and hard. The best tool was the large blade of my Swiss army knife. I had to apply a lot of heat for at least 40 minutes. It was not easy. The blade of the knife also gummed up with the adhesive and I had to clean it regularly with acetone. (Do it outside away from any heath source since acetone is very flammable)

In this situation and looking back at some of the other comments, I think the advice to remove the mother board and all its inputs is the correct way to do it. Applying so much heat to delicate electronic components is for sure not the correct way to do it.

Finally, in my case the screen was very fractured. For safety and hopping to avoid small glass going everywhere, I covered the screen with clear packing tape. That helped to finish the job without injury.
