Ipod 4th Gen Grayscale won't power off
« on: July 20, 2011, 06:35:33 PM »
I just installed 3.9 and cannot figure out how to turn the device off. Pressing play button does nothing and select + menu reboots the device. Idle poweroff doesn't seem to do anything.

Did you try holding Play?  Idle power-off should work.  Might you have done something to interrupt the idle period?  If it really can't turn off, it might be the same sort of problem as here:

Holding the play doesn't work. Looks like the ipod was on the whole night: the battery was fully charged when I posted my first message, now it has only couple of percent left.

I have used Rockbox successfully on this same ipod about a year ago, it is the latest version that does not work.

I tried the latest from SVN, still no power off. I wish there was a menu item called "Shut down".

This is almost certainly a hardware fault as described in the thread Chronon linked to; a shutdown menu option will not help you. The ipod cannot power off if it is receiving power from the dock connector, or *thinks* it is because of a shorted pin or other hardware failure in the charging circuitry.

Ok, I'll try with the Apple firmware.

EDIT: Is the shutdown same in Rockbox as in official iPod firmware as in it is not a real shutdown but the device goes to idle mode.

Rockbox shuts down the device completely. We don't have a sleep mode. The original firmware will probably be able to put the device to sleep.

I think it might be a hardware failure as you said earlier. I installed the firmware that I had earlier (3.5.1) and it won't power off. Seems to be working great with original firmware.

Apple's firmware doesn't ever try to power off the hardware, so it's not surprising that you won't see this behavior there.
