Introdução
If your Kindle does not respond when pressing the power button, but wakes and goes back to sleep sporadically, this is due to a malfunctioning cover sensor, which is a hall effect sensor located on the same flex cable where the LEDs for the frontlight are located.
On some e-readers, like those from Kobo, this sensor can be disabled in software, but disabling it on a Kindle requires a hardware modification that can be undone relatively easily.
Normally, fixing this would require a replacement of the entire display assembly, but what if you wanted a temporary solution to tide you over until you are able to replace the display assembly, or upgrade to a new Kindle (or other e-reader), and have the skills and tools to take apart electronics?
This guide requires that your Kindle remain powered on but in sleep mode, and that a plastic opening tool, and a PH000 screwdriver are used. You will also need to react quickly to disconnect the frontlight before it goes back to sleep again.
O que você precisa
-
-
Gently pry the bezel off the screen using a plastic opening tool. Start at the corners and slide around the edges until you return to your starting point.

-
Now comes the hard part.
-
Your Kindle may not respond to the power button, and disconnecting the frontlight at this point will leave it in that unusable state.
-
Tap on or bring a magnet close to the hall effect sensor.
-
When the frontlight lights up, immediately unplug its connector.
-
If your Kindle remains awake for more than 3 seconds, you may now put it back to sleep by pressing the power button.
-
If not, you may have to repeat this step.

To reassemble your device, follow steps 1-3 in reverse order.

Brilliant! I just went through the process of disconnecting my hall sensor harness to fix an intermittent wake/lock issue. It worked, but i didn’t realize I’d nerfed the backlights until after getting it all reassembled. Thankfully found this guide and it worked perfectly.
Cover sensor was malfunctioning after a battery replacement so I followed your guide and it worked wonderfully! Hope to get another 8 years from this thing instead of dropping it in a landfill! Thanks
Very clever! Thank you. In the event, changing the battery on my 7th generation Kindle Paperwhite seems to have fixed the problem with the cover sensor. That triggered a hard reset, so it might be worth trying that before continuing with this mod.
