Disabling Keyboard lights (work in progress)

**Malatesta** · #1 (**permalink**) 10-01-2006, 03:26 PM

Using RescoRadio and/or WMP, whenever I would "turn off the screen" (but keeps the device "on" to stream or play mp3s) the keyboard lights STAYED ON, which was really dumb.

Here are the reg keys to fix this as well as control all the KB lights behavior. Mabye this will be turned into an app by some nice programmer.

HKLM\System\CurrentControlSet\Control\Power\State

You'll see tons of folders, like BacklightOff, ColdReboot, On, etc.

In each folder, you'll find this:

kyl0 with a value of 4 or 0

4 = off
0 = on

This key \ScreenOff\kyl0 controls the KB lights behavior when the screen is turned off. Change it to 4 and soft-reset.

Awesome... Thanks !

Changing kylo value to 4 in HKLM\System\CurrentControlSet\Control\Power\State\ ScreenOff works perfectly while turning off the screen in WMP.

Having a problem with WMP though... see my thread.

Re-post from over at TC for others:

Hmmm, not sure what to say with this one as I haven't done a before/after with "disable backlight on alarms" with PA and this reg hack.

I can say when I just tried the "disable backlight on alarm" function and sent myself an email: backlight didn't come on, keyboard didn't light up and my LED starting to blink and vibrate. In other words all is working as it should even with this trick.

Have you gone back into the registry to make sure that the change took? You have to power off the device first (standby) and wait a couple of mins for the ROM to flush to RAM. If you just reset to quickly, you loose the change.
