Kindle E-reader: disable screensaver

* only tested with a Kindle Keyboard

The power button of my Kindle Keyboard stopped working all the sudden. When I toggle it, it doesn't go into sleep mode. After leaving it idle for awhile, it went into sleep mode automatically. However, I can't turn it back on!!

Interestingly, the power button is not completely broken. I managed to reset the device by holding the power button for 30 seconds. Once it finish reboot, everything (except the power button) continue to work. As a workaround, I disabled the screensaver so I don't need to turn it ON/OFF again.

1. press Home
2. press ↵ (the enter key)
3. a search bar would appear
4. enter ;debugOn
5. enter ~disableScreensaver
6. enter ;debugOff

If you change your mind, replace step 5 with the following command:

~resumeScreensaver
