Is it possible to completely disable the automatic activation of the screensaver? I don't see it in settings, the longest interval for this to happen is 1 hour, but no option to disable it completely. I already installed the No Lock app, but this only helped me to get rid of the slide to unlock screen. Thank you for any ideas.

All settings are here:
http://developer.android.com/referen...gs.System.html

In you case you'll need:
adb shell
sqlite3 /data/data/com.android.providers.settings/databases/settings.db
-- check current value
select * from system where name='screen_off_timeout';
120000 - 2 min
3600000 - 1 hour
2147483647 = 596.5 hours

-- set
update system set value='2147483647' where name='screen_off_timeout';
.q
^d

or you can pull/mod/push alternatively.

Won't disabling the screensaver keep the screen and IR sensors active, thus eating up battery life significantly when not in use?

I know some folks would like to get rid of the swipe, waking up on a screen tap (mostly for accessibility issues), but I think some sort of screen (actually, battery) saver is still important.

Great link, ApokrifX. Would you happen to know if WIFI_SLEEP_POLICY does anything on the NST? I use Tasker to shut wifi off when the screen goes off, but I wonder if that might be easier?

No idea.
I bet, it won't work...
Try and let us know?

I need to find a program that will let me know when wifi is on or off relative to the screen. On other devices, I can see that info in the battery status, but I'm not finding a similar option for the NST.

I *did* find a little program that would toggle it, but the NST lasts so long on battery, it's hard to tell if it's making any difference.

Actually, to disable the screensaver completely:
Code:
update system set value=-1 where name='screen_off_timeout';
I haven't found a way to disable the keyguard yet, but if you have one of the side keys set as Menu that dismisses the keyguard.

Hi Renate again ( you adviced me with manual time set in NST
http://forum.xda-developers.com/show...5#post30560605, thanks).
I like the tweak (to disable the screensaver completely) also. But not understanding how to do this in internal terminal. Not shell and not busybox know the sqlite3 app and update command?

I fixed it so:
you must install SQLite3 to the NST you can just push it to the device. [unzip sqlite3 (push to n2e).zip]

Code:
adb shell mount -o rw,remount -t ext2 /dev/block/mmcblk0p5 /system
adb push sqlite3 /system/bin

download it from here:

This makes a lot of sense... it explains my battery drain when the screen gets stuck on the "drag to unlock your NOOK" page after a reboot. Basically you have to make sure the Nook really goes to sleep.

Disabling the IR sensors and wifi are then the key to long battery life on the NST.

For anyone trying this technique: I used the pull/mod/push approach and Renate's recommendation of a -1 value, and everything seems to be working well, but I had to powercyle (power down, then power up) my Nook to get the change to take effect.
