Reset PRAM restart or turn it off and on?

Hi,
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 ??
Thanks,

Larry

Macbook Pro 17, Mac OS X (10.6.1)

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.

Thank you, Peter,
You say 3 chimes, the apple link says 2 chimes 🙂 whichever . . . but more importantly, I guess I should be turning the computer OFF, NOT just restarting. Thanks,

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.

Gregory, thank you very much. I believe YOU'VE put this issue to bed! SOLVED. (at least to me 🙂 You've also confirmed how I know the PRAM was zapped - by hearing 2 chimes!
