Are you referring to a forced shutdown or a normal shutdown via the menu item or clicking on a button that says shutdown.

Forced shutdowns are almost never required on Macs. The "Command option escape" key combination will allow you to quickly force quit any frozen application. Unlike Windoze this method is almost bullet proof.

I get the same issue, when I shutdown and start it up, or reboot it, zero brightness at start. Noticed this about 1 week after upgrading to SL on my first-gen Macbook... Didn't happen immediately after installation, either, so it's hard to say what it is. I thought my Mac was dying when I saw it didn't "turn on", but it was just the brightness...

Yup,

Same thing.

I like my brightness at the dimmest setting (like my mind...).

But it keeps getting bumped to the brightest.

Drives me nuts.

Any fix??

This even occurs when just restarted, Is there a work around or some simple fix that someones come across?. Was thinking of popping in my tiger disk and re-upp'ing from there. PLEASE POST FIX.
And not just say>>>"Easy enough, push button to turn your brightness down.Einstien."
Thanx in advance.

I have a similar problem, but not zero brightness. Both my brightness and volume get reset to the same level every time I turn on the computer. It seems to be a software thing, because I hear the startup chime yet once SL loads up the volume is set to zero.

Edit: After some searching I've found solutions that work for me.

For brightness: The max and min brightnesses don't "save". Pick a brightness one below the max setting (if you want it bright) or one above the min setting (if you want it dim) and it should save.

For volume: Delete the two files in HD>Library>Preferences>Audio and set volume to desired level, and it should stay the same after restart.

This is a rather curious feature (aka BUG!):

If you turn the brightness all the way down and reboot, then the system comes up with brightness set to full.

If you turn the brightness all the down, then back up it just one notch, the system remembers the brightness setting on reboot.

A couple of other beefs (aka BUGS!):

1) No way to disable the boot bong sound - damn you Apple! I know there are various 3rd party kludges the zero the volume level on shutdown and reset it back to where you had it. A kludge is a kludge is a kludge.

2) Why is it when you reboot, the system remembers the size and position of the Applications window when you open it from the menu, but never, ever remembers the size and position of the Utilities window when you open it from the menu?

Yup bring the brightness down then back up 1 notch and rebooting, also deleting the 2 audio prefs files and rebooting.. All seems to be fine now..

Plus I got 10.6.1 now so that might have fixed it too!

thanks all
