Kindle Fire HDX 7" Battery Replacement

Hi Cynthia, I found that the ridiculously strong glue Amazon used retained enough stickiness that I didn’t need to use any more. The battery is held in place by the design, and the black plate that you first removed is light enough that the residual glue held it nicely. but if not, some mild glue (not solvent based) should be sufficient.

Re: volume buttons, all of the back panel buttons (power, volume) and the USB port are run through the first cable that’s disconnected in step 5. If you are still having issues with volume once it’s been reconnected, perhaps check the alignment on the connector and make sure it’s fully seated. I’d also suggest not clipping the screen fully back in until you’ve tested everything; that way you don’t risk cracking the screen with repeated removals.

My battery too was bulging but once I replaced it, the device went back to it’s original flat profile so it doesn’t seem to have caused any long term damage.

Thanks Gary. I’m just getting ready to try and put it back together. I’m guessing I should try to charge the battery before I close it up.

Kindle is working!! The pictures were a great help. FYI - there are actually nine 3mm screws (step 8). The 9th one is under the press fit connector in step 6. Also, if you have never done this before, it’s really about a 6-8 hour job, 4 of which just to pry the Kindle apart. Be careful that you’re not just prying off the screen. It’s attached to the ‘guts’ which are clipped in there. So be patient. I’ve read too many comments on other sites where people cracked the screen. And heed Greg’s warning about reconnecting those 2 obscure press fit connectors. I was able to pull the ribbon on the smaller one under the metal piece and it was easier to connect. Also, once I replaced the pink screws, the sound buttons worked.

Cynthia and Greg, thank you for your helpful comments. I will be attempting to disassemble my Kindle Fire 7 HDX next week once the supplies and battery arrive.

Cynthia, did you charge the battery before closing the case to make sure that the battery worked?

Any other tips to avoid cracking the display screen during disassembly which I also saw is a problem with this particular model?

As for the step that Greg said was missing in the pictures above … how do you reconnect the two areas under the motherboard that Greg referenced when reassembling? Just realign them somehow or does the motherboard pop in over them?

As you can tell, I am a total novice at this.

And finally, is there a way to test the unit before putting the case back together to avoid having to open it again and possibly cracking the display?

This model Kindle Fire was the very best Amazon EVER offered. My battery is dying and if this battery replacement can remedy the issue, I would be most grateful!

Thanks again, Greg and Cynthia, for your input.

Greg and Cynthia, I installed the new battery following all of Blake's images and also with the guidance from both of you. I have not yet clipped the screen back in place, the Kindle is running and I am charging the battery.

I noticed the same thing that Cynthia noticed. I currently have no sound, however, I have yet to fully clip the screen back on and reattach the speaker bezel and screw back in the six pink screws.

Cynthia, you mention that once you reattached the speaker bezel and the pink screws, your sound returned.

Am I correct in thinking that this step will return the sound?I

I don't want to snap it all back together only to discover that I have no sound at all.

Thanks so much!

I finished adding the battery and found the directions 100 percent accurate for the disassembly. The assembly is another issue. When you remove the mother board in step 12, you also unplug the two ribbon cables beneath it. Assembly is next to impossible with two ribbon cables below the motherboard moving and not lined up. I was able to get slack on the large ribbon cable but the one with the smaller cable had no extra slack. I then took a small dremel tool and removed the grey structural tab the cable ran under This gave me the slack I needed for installation of the cables. Been two months now and the Kindle is running like new.

I was successful in replacing the battery (yay!) but managed to crack the screen in the process. I am assuming that is why the screen does not fully respond to touch - I can swipe but cannot enter the password, nor respond to ‘do you want to shut down?’ Or, might this be related to the difficulty of attaching the two ribbon cables under the motherboard? I can’t be sure that both of them are successfully seated. Thoughts?

Will this kit work for the first gen, 2011, HDX 7” fire? The battery on my 1st gen hdx is slowly dying, but otherwise the device is mostly superior to the 10th gen 8” fire I recently purchased.

Started this and foolishly I used a screwdriver on one spot instead of a spudger and cracked the glass. I even had the spudger sitting there that I'd already used - I'm an idiot (but I have spares). One thing about the "needed" list: aside from the T3 it lists a T5 torx when it's actually a T3 and a T6 as mentioned in the article body.

Thanks for a thorough disassembly method though regardless of whether I manage to complete a repair.

Hi,

I followed the directions but once I put it back together the screen is blank! What do I do?
