The processor speed and screen size should be all you need to get the instructions in this Knowledge Base document:
The link should open at the point in the document that addresses your model. If not, this is what is says for your model:
1) If the computer is on, turn it off.
2) Reset the power manager by simultaneously pressing and then releasing Shift-Control-Option-Power on the keyboard. Do not press the fn (Function) key while using this combination of keystrokes.
3) Wait 5 seconds.
4) Press the Power button to restart the computer
You don't have to enter a model number into the computer before resetting the PMU.
Thanks for the help.
The Knowledge Doc that you linked me to was the same KD (Title anyway) that I was perusing. And somewhere in there it wanted a Model Number. Anyway, all of that is history.
I just finished the PMU reset and the monitor brightness may have perked up just a trifle, but that may just me dreaming that it did. In truth, I have absolutely nothing to compare it to, so it is what it is. And, add to that the fact that I have recently purchased a refurbed 24' iMac whose monitor brightness nearly gives me a headache. Am now using Shades which helps a lot.
Back on topic: My old PB is still useable for my photography and travel, so this is not the end of the world for me - or it. Just old age setting in. Happens all the time.
I appreciate the help.
PS. How's the snow at your end??
Have you tried going to System Preferences > Displays and hitting the "Color" tab. You can re-calibrate your monitor from there, overriding current profiles to make the image brighter. As you are crunching images, you may prefer to beg or borrow a "spider" color calibration unit from a co-worker to get a proper profile. If you simply need brighter--if not correct--color, the Displays prefs may be the best path.
The pre-programmed color profiles on my PB17 (10.4.11) are all brighter than the one I created. Try those before creating a new one.
