Backlight reverting to 10 seconds

[meanvulcan]

I am posting this because 1) I don't think this issue is specific to one cooked ROM, and 2) despite searching, I can't find a solution.

The issue is that with all of the ROMs I tried that are based on recent AT&T or HTC 6.1 ROMs, the backlight reverts back to 10 seconds. I can change it through Backlight settings to something else, and go back to the control panel a minute later and see it's back to 10 seconds. Very annoying.

I've seen this with a couple of L26 ROMs, the stock AT&T 6.1 ROM, and the HyperDragon III Pro ROM which I am currently using. I see this whether I have S2U2 or not (I am on 1.22b now). My current set-up: HardSPL 3.56, HyperDragon III Pro Sept-17, S2U2 1.22b... but like I said, I don't think it's ROM-specific.

Calling all experts: is there a fix for this? (If you are planning on posting something like "I don't have this problem" or "Change your backlight setting through the control panel", please don't clutter the thread with your post).

Thanks!

I spent a fair bit of time searching this and testing various suggestions that seemed to work for other people, however I was constantly getting the 10-second reversion, plus the even more annoying dimming backlight when locked.
Anyway I posted this:

And now after removing the registry 'BatteryTimeout' my backlight is working exactly as I want it - i.e. backlight dims afer 30-seconds regardless of whether it is locked or not, plus when locked the backlight comes on when the screen is tapped.

Now wait for the various replies saying 'use the search'.....

FWIW, I too had this annoying issue, but found that using ROMeOS roms (last version is 4.6) I don't get this issue. Not sure why or what the chef did to fix it.

The chef has now moved onto the Raphael...so he is not working on his Kaiser roms anymore :(

Thanks, let's see if it sticks. I've tried quite a few methods I found during my search and those didn't work....

It happened to me also with akadonny's 3.29.DK.10 / SPL 3.56.Hard

I changed SPL in the meantime for a different reason, and I had no backlight issues afterwards, but still I would not link that strictly to SPL cause I changed many other things.

Anyway, I found a power setup that works for me very well:
- for "on battery power" I only use turn off device (uncheck turn off backlight)
- for "on external power" I only use turn off backlight (uncheck turn off device)


P.S. This never happened to me with earlier builds, only with 20748.1.4.0.

Well, the first approach didn't work. I have a setup similar to the previous post, but that hasn't helped. I am on SPL 3.56 Hard. Which SPL did you go back to?

[meanvulcan]

Second approach didn't work either. I see a lot of posts with people reporting the same problem... Has there been a definitive solution?

Im using HyperDragon_III_Omnia_20080818. With this ROM I dont have the issue of the 10 sec backlight. I use Hard SPL 3.29.

I also have this problem and it is making me sick, at night while in bed I am trying to read an ebook but I have to tap on screen every 10 seconds!!

I am HyperDragon_III_Omnia ROM and I have tried many tweaks no luck.


Edit...

Ok I think the problem is now sorted.
Here's what I did... changed the following registry - HKCU\ControlPanel\BackLight\ACTimeout set the DWORD to 0 and reset the device.

So far it seems to be fine.

Hmmm, I'll try this, thanks. This should be for backlight while connected... but worth a shot. I wonder if HardSPL version makes a difference... I'm on 3.56.
