The thing that turns the backlight on is a hardware switch, so no tweak in the software will affect this. Thus you have a hardware fault - probably with the switch less likely the leds. If its under warranty consider returning it. I would first check under the device in the keyboard mechanism in case any fluff etc.. has got in.

Keyboard backlight time

I know some people wanted to increase the keyboard backlight time. In case this hasnt been posted already, mad monkey has a cab for it:

No i have not seen this posted. tried on my qtek did not work - does it work on your device. i have seen a hack for the universal not wizard
cheers
nope this don't work on the T-Mobile MDA (US model)
Is it supposed to be a DWORD value? Anyone has gotten this to work?

No joy here
didnt work either on 2.8
nope - doesn't work

You would think someone at HTC would know how to do it. Do any of those guys/girls post on this forum?
not that I've ever seen - not on any of the official retailer sites either. good luck
p.s. the question might not be 'how to do it' but 'can it be done'
yeah, I'm beginning to believe that the whole thing is completely implemented with hardware: a keypress starts a LED "On" timer. This is also why the kbd doesn't illuminate when it gets extended. Even though WM senses this and flips to landscape, it has no control over the backlight: It takes a keypress to start the timer circuit that illuminates the backlight you see.
bummer.

Working under the assumption that it is indeed in-hardware, there would've been nothing to prevent the engineers from making the magnetic switch enable the backlight, too
Working under the assumption that it's purely software, there should be nothing to prevent WM5 from doing this... other than that nobody has coded it to do so
Working under the assumption that it's hardcoded in the driver, somebody would have to hack the driver to extend the backlight; adding functionality to turn the backlight on would be a bit more difficult.

I'll give you "glass half full" on that one :wink:.
However.... the magnetic switch would be more difficult to implement than a simple key press which also resets a timer circuit. You'd have to tie that additional input into a circuit that could be hard-wired with the keyboard itself.
there's my "glass half empty" viewpoint.... I've just got a bad feeling on this one..... sorry.
I guess I'm going to have to take a closer look at some of the disassembled wizard pictures to make up my mind on this.
I sure hope a way is found to fix this as well as control those other blinking leds.....
well the point was, basically, there already -is- a magnetic switch. It's used to signal the OS that the keyboard has extended, and allow it to react on that; the chosen reaction being that the screen orientation is changed.
There would be nothing whatsoever stopping the engineers who actually put the thing together (not talking about somebody taking it apart and tinkering in there and whatnot) to have hooked that up to the backlight control /if/ that is in hardware %)
And if it's in software, then nothing would have technically stopped the software developers from making the keyboard slide-out trigger the backlight that way; assuming they already do as much on keypresses.
exactly. But the kbd does't light up when you extend it you see.... This behavior shoud be obvious
ok weird doesnt even put this into perspective ... i edited that value and softreset my phone. backlight timeout is still 5 seconds and now my bottom ( previously skinned) bar has gone back to default colours ... tried removing the value and resetting again had no effect either ... lovely hack this is now i can try and figure out why the hell this just happened ... running newest official qtek rom only for info
I think this is one of the largest downsides to this device. When I pull the keyboard out the lights should come on AND it should be longer then 5 seconds. It would also be nice if it had a light sensor (like on the SMT5600) to know if the light SHOULD come on or not.
If someone (or HTC) would fix this it would be awesome.
oh, they'll fix it - for their next device models The Universal already works that way, and you can tweak the backlight time. I'm sure by now they've gotten all the feedback they need to decide that that is better than the fixed behavior of the Wizard (not sure who at HTC ever figured that would be a good idea to begin with).

SPV M3100 keyboard backlight, does it have one or mine dead?

Hi,
I got my Orange SPV M3100 on Friday and already i've noticed what i think is a hardware fault. Not a big fault and i totally love the phone (Skype over wifi an encrypted connection works perfectly), but i'm worried as the phone is only a day old.
The first few times i opened the slide out keyboard I thought i noticed a nice blue keybourd backlight come on. I say thought as i can't find any reference to it in the manual. However whatever i now do, i can't get it to come back on. I've installed a few applications, but i doubt they would have caused it to stop working.
I don't suppose anyone else out there could tell me under what situations the backlight should come on (or if one exists), so that i can test it, and if it doesn't come on, i can phone up and get a replacement sent out. Its not a big problem and i can still use the phone, but you don't expect hardware to die after only a day.
Thanks in advance for any help you can give me.

there's a small hole in the top right of the keyboard. This is a light sensor. So, if light's on your keyboar led will be off, and if it's dark your keyboar led will be on.
you have to press a button too before it comes on iv found.
there is a setting for it as well somewhere to turn it on
Thanks for the advice guys, but the keyboard still doesn't light up if i open an application that asks for text to be entered and then slide out the keyboard in the dark and then press a key. Looks like my light sensor has died. I've just phoned Orange and they are sending me a replacement for between 6 and 10pm today (what fantastic service!).
Same issue over here
Hello I am experiencing the same problem over here.
It worked for the person who sold it to me and now it does not anymore.
Do you know if this is an HW or SW issue ?
Any other cases around?

seems I have the same problem. i'm on orange and the light was working now it doesn't.
EDIT: no i dont have a problem. I went into a dark dark room and then typed something and it worked. if i cover over the "light sensor" with my finger and press a button, it doesnt work.
Indeed
Indeed I had a wrong interpretation of the function of the sensor:
The sensor works in the following way:
If it is dark AND there's a key pressed AND the setting in "Settings" is set to enable sensor THEN keyboard backlight is turned on if no light in evironment.
If the setting in "Settings" is set to enable sensor THEN keyboard backlight is turned on AS SOONS AS you press a key.
A little dumb from my point of view: if I slide the keyboard in the dark, is it to look at it in the obscurity? The simple sliding should turn it on by night.

I've noticed that the backlight on mine (Vario 2, it's a red backlight... urgh) doesn't come on all the time if it's dark or dusk-level, which is really annoying. Sometimes hitting the tab key brings it into life, but sometimes it just doesn't come on at all.
One of those 'temperamental', 'great idea in theory' designs methinks.
I also found out that if the turning screen backlight off on inactivity is disabled, then every time I slide out the keyboard, its backlight is turned on.

No Backlight on Softkets on Cingular 8525

This is really srtange. I thought that when improving a device engineers are supposed to take the good and add more features rather than remove essential features. I had a Cingular 8125 which was replaced by 8535. The Softkeys on hte 8125 are Backlit so itis easy to see in the dark, while on the 8525 the Softkeys no longer have any backlighting. The only keys that are Backlit on the 8525 are the Phone On(Green) and Off(Red) keys. Called Cingular Data Devices Support and they said that the keys are supposed to be backlit. But when I called HTC they said that the keys are painted. It is nice to know that Cingular is on top of this. Even their Technical people don't know!!! WOW amazing. While on the subject of Backlighting, the keyboard on the 8125 has better lighting as the numbers were lit in Red and the letter were lit in White. On 8525 everything is Blue, really hard to figure out. Maybe someone out there has an explanation for all this.
The keyboard definitely has a backlight on all the keys. What you may be experiencing is that the device comes defaulted with the keyboard only kicking on the backlight based on a 'light sensor'. I've disabled this sensor in the 'settings...buttons...backlight...(uncheck the box) on "enable keyboard backlight auto sensor". I found that even in dark settings the backlight sensor would not kick on the keyboard backlight properly so now the keyboard automatically lights up by just touching a key on the keyboard. Hope that helps!
The Softkeys don't have any Backlight!!!
My main issue is that why does the 8525 not have any backlight on the Softkeys (on the front of the phone, around the D-pad)???
Sorry...I too do not have backlights on those keys but hadn't really missed it since I mostly access those by feel.

No fair...the 8525 doesn't give this option.
It's the 8525 that does give these options. The 8125 doesn't.

Sorry, looked in the wrong spot. I found it! As for the 8125, it doesn't even have the light sensor, let alone the option to enable one.

Thanks for the tip... I was read to throw it out untill I read this
Thanks
Thanks dwcliff703 for your post, even though it was a while ago! I thought my keyboard button detector thingy was messed up or something and didn't know why it worked some of the time!

Keyboard light never, ever, works.

Got my Sprint Mogul a couple of days ago and having a tough time with the keyboard backlight not working.
I've done my searching and found that some people got their keyboard backlight to work by unchecking the option in Settings->Buttons->Backlight.
This didn't work for me.
Some people recommended just hitting a few keys and the backlight should work.
This didn't work for me either.
I'm looking at what just may be bad hardware and will have to replace the phone. That keyboard is damn hard to see in even the best low-light conditions. Forget about typing in the dark.
Does anyone know of methods that will force the keyboard to turn on so that I can test it?
unchecking the auto sensor option like you did should force it to come on whenever the keyboard is out, if it doesnt come on within a few seconds of sliding out id say get a replacement phone
I agree with defaultdotxbe...if unchecking the autosensor box isn't forcing it to be always on, I'd be worried.
I've left the autosensor activated, and my keyboard light works, but I must admit that it sometimes doesn't go on when I think it should. The sensor seems to be calibrated so that it has got to be pretty dark for the silly thing to decide to light up!
Having said that, someone on one of these forums came up with a pretty neat trick. If know I want to force the keyboard to be lit, I just slide it out about a quarter of an inch. The sensor is still hidden under the body of the phone at this point, and it thinks it's completely in the dark. The keyboard always lights up at that point. Once it's lit, then I slide the keyboard out the rest of the way. Brilliant, huh? You might wanna try that just to see if it makes any difference.
Good luck!
Thanks, peeps. I had the same problem with the keyboard light and was getting extremely frustrated. I tried the sensor trick (opening the keyboard 1/4) and, viola, it worked!

I also had the problem and after lots of searching I found out it was because I had the screen backlight turned all the way down. I moved it up to the first notch and now it works just fine even with the sensor.

This trick also fixes the orientation issues when turning on and it is in landscape rather than portrait.

Completely disable button backlights?

Hey guys,
I've searched but I can't find an answer. I'm using an Incredible S ROM on my HD2 at the moment that leaves the hardware keys constantly on when the screen is on - I don't like this, and don't ever need the backlight for the keys as I know where they are now. Is there any way I can disable this totally?
Thanks,
Zuka

Hey,
if your build is using the same init script as rafdroid you can try this:
create a file called "config.txt" on the root of your sdcard copy/type this line: auto_btn_backlight=0 - then reboot.
this is also worked with dandiest builds, so Might work for you.
Hi, thanks for your reply
I'm not running one of Raf's or Dandiest's ROMs, mine doesn't have an init script so this won't work. Is there any other way? Seeing as those ROMs have different button backlight drivers I'm assuming there has to be a way to control their on/off states
I'm not trying to be annoying by bumping, but this keeps falling off the radar and I'm sure there's a way to do this, if anyone could point me in the right direction that'd be awesome

Sound like an unstable ROM. My only advice is to try a different one. If you like pure android you can try tytung's ROM. It's the best, just follow my sig.
...what?
Why does my ROM sound unstable? The button backlights aren't actually causing a problem, I just don't need them. Ever. I'm looking for a way to disable them, but I like (love) my ROM after months of searching

Hey
guessed u didnt have a rom from raf or dandi, they havent released an Incredible S build yet.
mind telling us which Incredible S you have or is it a secret
& you are right, it has nothing to do with stability, its the newer light drivers, this was implemented to fix the led notifications, not sure if you can change this (always on) behavior without going back to the old drivers.
p.s. how do you know your build doesnt have an init script, have you tried the config.txt?
Hey mate,
I'm using Korand's stripped down Incredible S build - http://forum.xda-developers.com/showthread.php?t=1019489
The reason I'm assuming it doesn't have an init script is because, apart from the battery percentage icon, I think everything else is stock, judging from Korand's first psot. It's hard to tell because there's not much support for the ROM
I wouldn't mind going back to the old light drivers though, or just rendering both the notification LEDs and button backlights inoperable. Don't use either really
bumpity bumpity yeah

Theres an app in android market for that...its called "ADJ Brightness" which basically allows yoy to adjust and lock the screen brightness. It can be set to extremely low (much lower than android lowest setting...or extremely high, again higher than android default max
But if you hit menu then chose "options" there near the bottom you will see the option to Lock the button lights OFF...works a treat and saves me a lot of battery jiuce. Also in this options menu you can chose to have the little charging led either On or Off...I find this used in conjunction with "button saviour" and another app that allows me to wake the phone with the volume rocker means i dont need to use the H/W keys at all
Dont know if this is what your after but hopefully it may help.
Thanks Con, I installed the app
It does let me control the hardware buttons, allows me to turn them off, but whenever I press them they just come back on again, despite checking "always off" in the settings
But at least this shows that they can be controlled, even on an HD2
any other ideas?
Ah, sorry zuka, i have only just noticed this as well...yes it seems the backlight does reactivate when i again use the buttons. However i am using Rafdroid 4.2 rom which allows the backlight to off after 10 seconds. So i guess your issue does lie within your rom
I no longer use the hardware buttons (or very rarely) instead i opt to use the onscreen replacments within button savior, Which is why i didnt notice that the backlight does re-activate when the buttons are used...this seems to overide the adj.bright app. But like i say my light is only on for 10 secs or not at all using adj & BS.
Sorry dude am at a loss as to how you could fix this as it does sound frustrating
Nah, thanks for your reply anyway. It's not like this is a horrible bug, it's just annoying because I don't want the hardware buttons at all, I know that they can be controlled but I just can't figure out how to keep the damn things off...
if anybody has any other ideas, I'd welcome them. at this point I'm stumped
Has anybody been thinking about this for a while and has a solution?
Hey
ADJ Brightness should do the work for you
just play with the setting( Menu-option)
lock screen brightness, so it stays off.
good luck
tried this app a while a go and it solved this problem.
