What does Command + Option + P + R actually do?
I found the startup button combination mentioned in the troubleshooting guide, Command + Option + P + R and lo and behold it worked. Can anyone share with me what that does to help it start up? And possibly, more importantly, what problem is that showing or foreshadowing if I needed to use it?
The issue started last night I plugged in my shuffle to let it sync and charge, came back to my computer this morning and iTunes hung up (beachball), then iPod showed 2 icons in iTunes (one mine, one generic), then after a couple minutes of mroe beachball said iPod may be corrupt and I could not Force Quit anything.
Powered down, and when I powered up, I got a grey screen, no apple icon, no spinning line, no folder/question mark, nothing. I tried to start up from the restore CD ... and would only allow me to try and install. There was no hard disk that could be located at all to select or try to repair? I'm fearing for the life of this laptop, and it isn't that old. I'm curious what the button combination assisted with so I can be aware, or know if there is something I need to do now that it finally started back up and "appears" normal. Thanks for any more info, sorry for the long post, but thank you for reading.
Very nervous,
