Power button not working correctly after digitizer replacement

Hello all. I have an iPad Mini 3. I recently replaced the touch screen because it was cracked and now the Mini doesn't lock or wake with the top power button, however it works when holding it to shut the Mini down.

Unlike the Mini 4 and newer, the 3 doesn't have a sleep/wake sensor that needs to be transferred over from the original screen.

Thinking it could have been the aftermarket digitizer, I tired disconnecting the home button and digitizer at the same time, then just the digitizer but got no change with the power button.

Any help would be greatly appreciated, thank you.

Hi Dmak,

I went through the digitizer and power/volume button replacement guides, but I don't see anything that makes me think the digitizer replacement would have damaged the power button. So at this point the power button problem should best be treated as its own issue, unrelated to the digitizer.

You might want to try as many reset/software solutions you can think of, including a hard reset, resetting all settings, even up to a full backup/wipe/restore.

If that doesn't do the job, then my next suggestion would be to follow the Case Button Assembly guide and pull the power button. Remove the electrical part and clean it with isopropyl alcohol (90% concentration or higher), then take the physical button out and clean it as well. Finally, before putting it back together, clean the connector on both the cable and the motherboard.

If that doesn't do it, you might have to consider replacing that assembly, but personally I'd definitely try cleaning it first.

Hey Jerry.

Something I completely forgot to add, I have tried a new power button flex already with no change, it behaves exactly the same way. In fact, after trying the new flex, I turned on assistive touch and even the on screen selection guide to lock the screen will not work which actually only compounds the issue, is the problem hardware or software, can it be both? Who knows?

I have completely reset the iPad once, but I will definitely try again. Thanks.
