In my endeavors to find out why my PDN discharges while supposedly in sleep mode, I noticed that when the screen times out the first step is for the backlight to go out (OK) then 3 seconds later, the unit goes into sleep mode. During that 3 seconds, I can turn on the backlight with a screen touch, but after 3 sec. I have to slide the pwr switch. I only just noticed this behavior & I recently installed SystemPanel & set the screen timeout to 2 Min. with "sound & Display settings" under "settings" app in LauncherPro. I have reset the screen timeout back to 10 min & will see if it behaves the same. Thing is, I can't find anywhere to set up the auto sleep parameters, like how long inactivity causes sleep mode. Any ideas? It didn't used to do this, I'm pretty sure. kevEdit: Screen time-out back to 10Min & same 3 sec. window before sleep.???? WTF???
