Device gets stuck in dimmed backlight mode, AC or DC
 

I'm sitting here watching my phone hang out in a dimmed backlight mode. It's been this way for several minutes, and occasionally it bounces back up to full brightness (i.e. as configured for given power mode), but seemingly never into lights-out mode.

Any idea why this might be happening?

If it's on the charger, there's different backlight timeouts for external power and battery power in the power settings...

To be sure. But this is simply bouncing back and forth between dim and full (configured) brightness. Every 30-60 seconds or so. And after reset, it doesn't do this ...well, not until it does.

If it's on the charger you could always hit the power button to turn the screen off? I know sometimes my screen will come back on for whatever reason but I just hit the power button again.

The problem is that I'm often not there to turn it off. I'd like the phone to go black--lights out--as configured to do. 1 min for external power, 30 sec for battery.

I also just found another thread where others are having a similar problem. When plugged into a usb charger (or perhaps even an A/C - D/C charger as well), the light will dim but never go off (as opposed to bouncing back and forth from dim to bright every 30 secs or so). I have the same problem as well.

By chance, did it happen when you had the phone keys locked. I had this happen when it was locked the other day and the only way to get it back was to try everything to get it back. Finally, I just hit the soft reset.

Weird, I have the same exact settings and it works for me. I have the screen set to dim after 30 seconds and turn off completely after 1 min on battery power.

I just changed it to dim/turn off after 1 minute when on external power. Plugged my phone up to the charger and screen just dims but doesn't turn off. Strange...

I'll tell ya, I love gadgetry, but I really hate gadgetry that doesn't work. It seems that all too often things go to the shelves that just aren't ready. Hell, even my coffee grinder and toaster can't get it right.

Anyway, I'm not sure what locked keys are, exactly. Is it different from disabling all-but-power buttons when the device is supposed to be asleep?

I hear you about the gadgets thing. But that is what cellphones in particular are all about. Generally, they are cheaply made and crap out before your 2 year contract is up, causing you to buy yet another phone. It's just one big inefficient cycle. Essentially the consumers are the "beta testers."

I believe he was referring to the lock behavior found under:

Start > Settings > System > Long Press End Key & Key Lock

I use s2u2 with the option enabled to automatically turn device back off. If my phone wakes up and is not unlocked within 8 seconds (user configurable), the device goes back to sleep.

I've also found the "don't wake up for SMS" registry settings don't work, my phone still wakes up.
