K3 Help! Kindle 3 Power Switch is dead

CAVALENCIA · 05-10-2019, 10:58 PM

Please your help. The power switch in my Kindle Keyboard is damaged and I don´t have a way of waking the device up. Is there a keyboard shortcut or key combination that has the same effect than sliding the power switch?

This device has the latest firmware so I don´t think I can root it. If I reset it by disconnecting the battery, it boots and I can use it but when it goes back to sleep I don´t have a way of waking it.

I can also try a hardware hack; I have changed the screen of this device twice but the power switch is really small and I don´t think I can replace it.

Any help is highly appreciated.

I think I found a viable solution. Following the guide here (https://youtu.be/wyO5cjuqF4g) I enabled the Debug mode and using the command disableScreensaver I stop the screensaver and the Kindle will never lock. This of course has the issue of possible key presses but I keep it in a case so it shouldn´t be an issue.
What I don´t know is if I should keep the Debug mode active for this to take effect or if the Debug mode has any effect on battery usage or functionality in general. I will test and post here any findings.

you can try to connect the terminal by yourself
the switch had 4 pin, 2 on the top and 2 at the bottom
the top was connected to the controller and the bottom connected to the ground, get a something to short the top pin to the ground. i find it works last time, and then i just disable the screensaver

I think one of those cases that use magnet to sleep/wake the device could help. I don't know if the Kindle 3 has the appropriate hardware or not. Works well in PW3. Only had to use the power button maybe twice in almost 2 years so far after getting the case.
