For those experiencing the "failure to wake" issue...

[i360]

Had this happen twice with a famous brand ROM from here and it scared the s... outta me. I have since switched to many many different ROMs and its never happened again. If your running stock with this issue then I don't know what to say.... Replace?

ya know I specifically opened this tab because I wanted to say the same thing. I got an SRS audio WOW cab from a friend. When I installed it, it failed to wake almost half the times. I uninstalled that cab and voila! it works fine.

Maybe those roms have some flavor of that cab installed?

I think this happened once on Mighty ROM (I ran it for like 2 days). Been on my own Kitchen ROM or Energy ROMs since and this has never happened in like 2 months. Or on my wifes Pro2 either (Same Energy and Kitchen ROMs). Never happened on Prior WM phones either. This the first phone I've run custom ROMs on. My wifes did suddenly drain battery real quick (in a couple hours once on the Energy ROM, not sure what caused that may have left something stupid running).

I do try to keep things simple in both customization and apps.

I've only start having this issue when I upgraded to the official 6.5 release. It appears to happen with apps that takes up a lot of memory. Sometimes the screen will come back on with a few toggles between the end key and backlight key...others, only w/ a soft reset..

happens to me .. if i slide off the back cover or put a little pressue on the back cover as if im gonna slide it off screen comes on .. if im not mistaken i hard reset the phone after the first time this happened but only cuz i wanted all of annoying SPB mobile shell the hell outta my phone

Can anyone replicate this situation on demand?

A specific situation or running program that does it every time when the backlight timer kicks in?

I, too have only experienced this since 6.5, and its pretty discouraging.

I am one who made a thread about this problem.

I flashed to Mal's 6.5.3 and haven't seen this problem yet.

Have never once had this happen since I started cooking my own.

OK. I must have jinxed myself by starting this thread... because last night my phone started doing this NON-STOP! Didn't matter which battery I used, or how snugly it fit in the device. Pulling the stylus, opening the keyboard or any combination of buttons. Whether the screen timed out automaticlly, or I turned it off. I tried resetting a couple dozen times and using the device for a bit and it would function just fine... but as soon as the screen went dark, IT WOULDN'T WAKE AT ALL UNDER ANY CIRCUMSTANCES!!!

So since this was happening EVRY TIME(!?!) I figured I had a good oppertunity to see if anything else would effect it, or if I could find a cause. And, well I think I figured somthing out:

Each time my device had failed to wake, I've been in the dark, or at least in less-than-ideal light (like last night running MemMaid or checking e-mail or whatever before I go to sleep). Ironiclly, I was going to log onto this thread and say my device had't done this all day (serves me right, I guess).

So after resetting and trying different things, here's what I found and would like others to try: Turn off the auto-adjust backlight

To do this, go to the HTC Settings tab and select "All Settings" button. From the next screen, select "System" and goto "Power". In the power settings, select the "Backlight" tab. Uncheck "Auto Adjust Backlight" and pick a brightness setting that works for you. Reset and see how things work for you over the next few days. As soon as I turned it off, my device worked flawlessly under conditions where it was consistantly failing to wake.

So for me it seems whether it's a hardware or software issue, it seems related to the light sensor determining the brightness of the screen.

I'll keep my fingers crossed, try it for a few days (or nights) and report back.

This was definately caused by the SRS Wow HD audio program. Once I un-installed, everything worked as it should.
