To reset the PRAM, I typically just restart the computer while holding the "Option Command + PR" keys. Never seems to solve whatever problem I'm having - but all works well.

Am I doing this right?? I just read you need to shut down (meaning turning the MacBook Pro off?), and start up the machine while holding said keys for 3 chimes.

Will a restart while holding the keys do it properly, or must I shut the computer OFF first, then turn it back on?

Maybe I've been doing it wrong ??

You have to shut the computer off first, then hold down the keys before the grey apple boot screen. Keep them held down until the 3rd chime - each chime is like a mini reboot, the DVD drive also makes the sound it does when the computer usually starts up.

2 chimes is all that is required although 10 chimes will not hurt, it just won't help is all.You can also do it on a Restart. As long as you get the 2 chimes you know it has been done properly. Again, is you get a total of 3 chimes it makes no difference.
