[QUOTE="mac4, post: 297945, member: 24699"] [b]a related issue[/b] I had a Powerbook 667mhz and upgraded by moving my HD to a Powerbook 800mhz. Unfortunately, on the newer machine, the Energy Saver (machine cannot go to sleep, and won't even dim), and Monitors Control Panels do not seem to work properly. I have just one screen brightness level... brightest. I have just two screen options... 640x480 and 1280x854, in both color and screen depth in the Control Strip (this is in system 9.2.2). And I think the ATI Graphics Accelerator Extension is crossed out (not loading) at startup (I think it's this one, based on the icon). I don't think the ATI card is broken, because the keyboard brightness buttons do work in system X. And... the screen also has the second monitor/display continuously activated, even though I had never previously attached one to the laptop. I did plug one in after the fact, to confirm the second screen being active (and it worked), but I didn't seem to have the option to turn it off, and no additional screen resolutions appeared. So, as in the original posting here, can I disable the second display?... and additionally, if anyone knows how to get my other features back also, your assistance is humbly requested... thanks.
