iPod 5,5 (80Gb) doesn´t switch on anymore

[bluebrother]

just because it's not running at start-up doesn't rule out Rockbox as the cause. It could well have got the iPod into a state where it couldn't start-up the next time.

Well, in that case the Apple firmware which is responsible for startup (and not on disk but in the flash memory of the Ipod, so it isn't touched by Rockbox at all) would do some handling. I'm pretty sure it would display something like the sad Ipod image or the "contact apple" notice if the disk is completely unreadable.

I guess the only way it could be the same problem was if it was left in the "deep sleep" state long enough to completely drain the battery.

As far as I know the Ipod turns itself completely off after some time in the deep sleep state. It's be a couple of days but I don't know about the actual values.

You're assuming it's actually shutdown and not in some hung intermediary state.

If it's not in the official "deep sleep" mode but in some kind of purgatory it may be unable to turn off.

Maybe he could try leaving his iPod for a week (to be safe) and then charging for a day or two via AC.

If it weren't shut down, the hard reset combination should reset it, though, if performed properly. I assume you're suggesting that, for example, it hung on the write of the settings to disk during shutdown perhaps, not having enough power to perform the write?

[DefineByte]

The hard reset would work, unless the battery had been fully discharged while it was hung. I wouldn't speculate on the cause of the hang. I'm coming from a position of ignorance.

Maybe a string or something could be written as the last action to be performed by the firmware and see if it gets that far when it hangs (see if it's there on next boot, post-hang).

Hi Lorean,

I was doing what all of you were suggesting to me, i charged with a wall charger and for a long time...... for me long time means more than 4 hours, if you say now that i have to be more than 24 hours charging....ok that is something new for me.

I repeat it. I was doing was i was supposed to do, I charged from differents computers, usb cables and wall charger..... so i was a good boy.....
my complain is only the way to say the things. I was more than 4 days trying to charge the ipod in different ways and then next day i read from a developer..... "Charge the ipod"..... my God!!! that is what i was doing the whole time.

anyway, i will get today my third ipod (i have to say that apple support is working very well to me) and i will try with a new release, so you can see that i believe in all of you and in your work....  ;-)

if i have the same problem i will try this time to charge the ipod during a week if you want me to do it

My first suggestion would be to never hook it up using the USB cable and port that you hooked the other two up to.

My first suggestion would be "don't let the battery run down that flat ever again"

If you ask an apple store when things like this happen you should use a WALL charger and not your USB on your laptop.  I was sitting at the genius bar when a girl with the exact same thing happened.  The apple guy just plugged it into a wall charger and not a usb port and it came right up.  he then went into explaining that the wall charger is a better option than the USB port and that the ipod will respond to that when it won't respond to the USB port.

You read the part where he said he tried a wall charger, right? :p

[GodEater]

And you read the part where I said "it may take as long as 42 hours for it to recharge" right ?

[Llorean]

The wall charger gives twice the current a USB socket can output, I believe. So yes, there is a difference, but that was suggested during the series of things.

Yup, I saw that thanks.

I'm disappointed that the iPod is going back (understandable of course). It would have been good if it could have been used to get to the bottom of the problem. I'm sure it will happen again.

I had this problem with mine, I temporally uninstalled rockbox because of it,
I had to reset the ipod to switch it on after a battery charge, it drained my battery from full!  

I'm telling you this so its known that its not an isolated incident, I don't know much about it, but I'm thinking there might be a bug with the 80GB?

There might be an issue with the 80GB hardware or apple firmware. That is nothing we can do anything about -- powering up is controlled by the apple firmware, so if it doesn't power on it is definitely *not* a Rockbox issue.

Did you charge from within Rockbox? How long between when you charged the iPod and when you next tried to use it?
