Ipod turns on to a white screen sometimes

I did not say that it definitely is due to Rockbox. I just said that I don't know. So far, with 5g_shutdown_by_of.patch I never had to reset my 5G 30GB iPod to turn it on. I'm growing more and more convinced that the patch helps, but I want to give it more time.
I recognize that even if the patch helps, that doesn't mean that there is a bug in Rockbox. There might be a bug in the OF which is triggered by Rockbox.

Hi Dreamlayers
I haven't installed any of your patches yet because I discovered a new thing today so I wanted to get your opinion on it.
For the first time ever, today while listening to a track, the player shut down completely and I wasn't able to start it up with just pressing Select (or any button) and I had to the Menu+Select though it started back up properly (no white screen)
Does this mean is the power circuitry? and if so, is there a software patch for it?
dreamlayers:
How is your battery? A severely worn out battery might cause problems. What's your typical battery life? If you're unsure, run use the battery_bench plugin to check. See:
http://www.rockbox.org/twiki/bin/view/Main/PluginBatteryBenchmark
If an unexpected shutdown happens when the battery is not worn out or discharged, power circuitry and related electrical connections could easily be the cause.
I provided the past two software workarounds because I felt I had a good understanding of what could help, and the workarounds were safe. I am not providing a workaround for the unexpected shutdown because I do not have a good enough idea of what could help. I'm not even sure if the problem can be helped via software.
BTW Note that a workaround isn't a fix. It doesn't fix the problem, it just does something differently to try to avoid the problem. The first one reinitialized the LCD when Rockbox starts. If the firmware in flash fails to initialize the LCD, Rockbox initializes it and hopefully all is good. The second one was an attempt to reduce the number of times you have to reset your iPod to turn it off.

Well I left it playing one album overnight on repeat while running the battery benchmark and when I woke up, it was off. I turned it on (was able to do it normally) and battery is at around 40%, so it turned off on its own again at some point last night.
I've attached the file on what data it has so far, however I don't have excel so I can't actually plot the data :( Any chance I can bug you for a minute of your time so you can tell me if this is good or not?
Also I've had a better battery installed in this player (850 mah) but I only ever get about 8-10hrs playtime MAX which to me seems on the low side for an 850mah battery (though I do play a lot of FLACs)

Well I think more and more its the connector itself as when I played with it, I actually managed to cure the white screen once.. however since its been happening more and more.
I've sent it back to the guy who modified it for me to verify these findings.. I think the wire gauge and the bend in the line out dock (imod version) was too much stress for the connector
I'll report findings later when he receiver it and inspects it for anyone curious
Thanks for trying dreamlayers :)
