I followed these instructions and have successfully replaced the battery. Everything is working great but I have one problem. The corner of the screen above where the ribbon cable connects the screen to the mainboard refuses to stay put. I even pulled all the old double-sided adhesive off and applied brand new adhesive all the way around the contact region but that bottom corner keeps popping up on its own. I suspect that the act of taking the screen off straightened out the (previously bent) ribbon cable turning it into some kind of spring that keeps pushing the screen up. How do I fix this? I have taken this ting apart and put it back together multiple times.
I performed this replacement. I used a heat gun - the screen was still difficult to remove, and I’m not sure if the heat helped or not. I also used suction pliers made for pulling screens apart (you can find these for around $12 or so). If you use suction pliers, you hold the tablet in portrait mode and suction at top right corner keeping the screen pinched together at bottom left corner (reason: the ribbon cable connecting the screen to the tablet is in the bottom left corner and you don’t want to damage that when suctioning the screen away from the body). I also used old playing cards to help work the screen loose from the body (old playing cards work infinitely better than the pry tools in my opinion). The screen is held in place by 1mm double sided adhesive tape (you will want to order a roll of this for putting the tablet back together, so be sure you have some ready, it’s not expensive).
Getting the old battery out is a real pain as it’s stuck to the body using a couple very thick strips of double sided flexible adhesive tape, and this is where you will want to make liberal use of the heat gun on the back side of the tablet. Be very careful pulling the old battery out - lithium ion batteries are known to combust if they are traumatized too much. I’d recommend wearing safety glasses and have a fire extinguisher handy.
After getting it all back together, the tablet accepts a full charge, and I can now run it down to 1% before the tablet turns off on it’s own. I’m super happy with the battery swap.
