derFunkenstein Posted February 14, 2012 Share Posted February 14, 2012 I got an M4300 off of eBay for super-cheap. It's got the T8300 2.4GHz chip, 4GB of RAM, a 250GB hard drive, the Quadro FX 360M, and a 1920x1200 display. Everything works - everything - except for brightness options. I can't lower the brightness and it will not dim itself. Instead, the image on the screen "freezes" (only to come back to life when I move the mouse). The screen doesn't sleep at all, though it does go out once the computer puts itself to sleep. I searched the forum and searched insanelymac and came up empty. Nobody else seems to be dealing with this. Any suggestions? Link to comment Share on other sites More sharing options...
derFunkenstein Posted February 15, 2012 Author Share Posted February 15, 2012 OK I figured it out. There's no brightness slider, and the default brightness shortcuts using Fn+ arrow keys work. On my D620 brightness is controlled by the Pause and Scroll Lock buttons so I had mistakenly assumed that the same is true of the M4300. My bad.
