Jasjar Keyboard light/Backlight button

Is it possible to enable the keyboard light via the backlight button? I believe this would be a very useful function since the keyboard light only comes on when it is very dark and not under poor light conditions.

Probably you will just need to find the registry key that controls the backlight button and then associate the relevant keyboard light trigger to the registry key. :shock:

Thanks, however it is the keyboard light I'm interested in. Do you know how to enable that?

I'm sure thats what Meatychi just said

Go to Start>Settings>Button>Backlight and Disable auto sensor. This would enable the keyboard to light up as soon as you press any key for 10 seconds. If you want the keyboard light to light up more than 10 seconds, follow this instructions from the WiKi pages:
How long will Universal keyboard shine? 10 seconds is a few, change the value of this key and it will shine so long as you wish!
?HKEY_CURRENT_USER\ControlPanel\Backlight\QKeyLedTimeout

OK - I think I need to clarify this. What I would like to do is to be able to turn ON the "keyboard lights" using the "backlight button". I know how to program the backlight button and extend the "light on" time for the keyboard (thanks to previous posts). Being able to turn on the keyboard light by pressing a button (regardless of what the sensor thinks, and not having it come on when I don't need it) would, I think, be an advantage.

Further.....
I do not want the keyboard light to come on everytime I press the key, for instance in bright daylight. The sensor turns the light on in almost pitch black, so that's ok. In poor light conditions the sensor does not turn the light on and it's difficult to see (at least for me), the small keyboard Fn icons. Hence the reason for having some other means of control.
What in fact I need, if anybody knows, is how to trigger the keyboard lights (apart from hitting the keyboard).

I haven't tried any of this, so this is all just speculation, but here is a thought...
I believe that there are programs out there that will simulate a keystroke. Assuming you can find one, and assuming that a simulated keystroke will turn on the backlight, then you may be able to assign the keystroke program to the backlight button. You'd have to pick a harmless keystroke, like the shift key, and it's not pretty, but it may work.
Good luck,

Keyboard light from Backlight button

I remembered reading some posts concerning using the backlight button on the Universal to turn on the keyboard light but I can't seem to find it anymore.
Can somebody point me in the right direction to map the backlight button on the Universal to turn on the keyboard light?
Thanks.

Just stick your thumb over the sensor =)
I think that was the advice in another similar thread.
There is a registry hack to make it stay on longer than the 10 seconds that is selectable from the control panel, mine is set to 30 seconds.

Increase Keyboard Backlight Time

Is there a way to keep the light of the keyboard a bit longer?
Can i do something via registry?
Thanks

Change the keyboard backlight duration
To change the duration of the keyboard backlight, you can set (example is 30 seconds):
Code:
HKCU\ControlPanel\Backlight\QKeyLedTimeout = 30 (DWORD decimal)
Please note that this may not work on some devices. One such notable exception is the HTC Wizard.

Best...thanks.
Now, the second question.....and most usefull for me.
Can we keep the keyboard light on all the time when the device is under charging?
This could be perfect for inCar use while charging.

Nothing ???.. :?

I'm looking for this answer since long time... and, even if I didn't find the answer, I'm glad I found somebody having my same question (even if some months ago)! ... better than nothing ...it's a start.
So anyone knows how to keep the keyboard light always on when device is on charge?

i wish you could change the color
for colorblind (red/green blind) people RED is useless.
PLEASE STOP USING RED FOR ANYTHING!
thanks!

:shock: I don't know if you mean the red on the flag, the red of vodafone logo or the red of the keyboard... but I will change all of them if you find the answer! :lol:

I changed it to 65535 and the registry editor seemed to accept it, I make that about 18 hours before it times out, nice thing is it still goes out and stays out if you power down, but it goes out and comes back on if you close.
Regards

I've written an app to give independant control of the keyboard lights (and red/green keys), manual on, manual off.
However, gooroo's solution sounds like a better workaround.

Still looking for a solution for this one too.
I don't think I can use the change timeout to 65000, because my device doesn't autoswitchoff (disabled that) because the BT keeps f*cking up.
So after 30 sec my backlight just turns off, the device keeps on. Setting the keyboard timeout to 65000 would kill my battery cause it will always be on.

Viper, so what do you propose? You don't want to extend timeout?
V

I've always had set it to 30/60 seconds.
I think the problem is that wm5 doesn't support keyboard backlight like the normal backlight (which has settings for battery/AC)
just trying 65000sec and see if that works a bit. But I have to see if it doesn't drain the battery and all.

-update-
Ok this option works perfect for me.
And yes changing the value to 65000 will let your keyboard light be on permanently (practicaly then)
But your keyboard light auto-switches off when your Backlight does.
So in the car it's on power, so this will keep the backlight on full brightness + always keyboard lights
on battery the backlight goes out after 30 sec and so will the keyboard. But when i touch the screen both will jump on.

Is there a way to keep the light of the keyboard a bit longer in HTC Artemis/P3300?
Thanks

Keyboard Problem

Hello I'm having some problems with my Htc Hermes (I-MAte JASJAM)'s hardware keyboard backlight problem.
whenever i open the keyboard it lights up and when i press a key it goes off (weather its dark or not)
I have tried to uncheck / check the light sensor option in the settings but it didnt help.
I dont want to hard reset could you provide me with default keys which are in
HKEY_LOCAL_USER\ControlPanel\Backlight
Thank you

this seems to be exactly what im after. i am aware that this is an old thread but i am after the settings for the backlight registry as above.
my backlight seems to flicker on and off as im typing, which is rather concerning and irritating. any help would be great.

There is a "light sensor" setting? I looked everywhere for it but can't find. I would want my keyboard backlight on 100% of the time if my Hermes is slid open...if there's some way to jury rig that feature, I'd be pretty psyched. Somebody help!

Backlight woes

Hi,
I'm trying find out what reg key is used for setting the backlight off level.
At the moment, after the 30 second timeout, the backlight is set to dim (1) - what I want is to make it completely shut off, without turning off the display.
Before I get told to search the forums, there are a few threads and certainly one or two have already asked, but none have a solution.
I've tried setting various levels such as under HKCU\control panel\backlight - i was thinking that onoff or extonoff may do what i want, but to no avail after a soft reset
Any ideas?

Dunno about what reg key this effects, but it sounds like you're looking for the timeout settings as opposed to the backlight settings.
This can be found in the control panel, under power -> advanced, and here you can set how long it takes to hibernate the device.
Not sure if you still need the reg. settings, but it might help to know that backlight entries are probably the wrong place to be poking!

What's the model of your device?
Some manufacturers like to go proprietary, eg. ASUS, in which case, you will need IDA and hack your way through.

HTC 3300 with either WM5 or 6 - it's not timeout settings or whatever, even if i set the backlight to as low as possible within the OS, it is always slightly on.
It appears the OS sets the BKL value from 1 to 4, 1 being dim, 4 being max brightness.
I can get it to turn off by setting the value to 0 manually in the registry and doing a soft reset, but thats not exactly ideal - I just want the device to stay active but without the backlight as thats what uses up most of the power.

my 2 devices, O2 mini and asus P535 allows the display to stay active and the backlight off. this can be achieved using the control panel applets which implies self-developed software can do the same.
so the question is, can your device achieve that state using built-in applets?
if it can't, then it's really a gamble for you to spend time finding a way.
i'm assuming that when you set the registry to 1, your backlight turns on slightly? most devices can't be viewed properly without the backlight, so in my opinion, there's little point in leaving it on without the backlight.
why do you need the display active? perhaps there is a better alternative to reach your goals, eg. LEDs

[HKEY_CURRENT_USER\ControlPanel\Backlight]
