I recently bought a 2.4 MBP model a1260. When I got home I become aware of the volume keys were not running, and then I noticed none of the function keys were running correctly. (Illustration, f12 demonstrate an eject CD symbol). So, the keys are running but not doing the standard functions such as volume and brightness. I have create certain and unchecked (and restarted) the "use all f1, f2 as customary function keys" to no result.
Some additional wired things that seem to be related are: In the volume window in SYS PREFS the entire volume effects are grayed out. Under OUTPUT and INPUT it says no apparatus found. When I go to the itunes accumulate in itunes and I twice hit it off on a song, it would not play. Not merely is there no volume, but song would not play. Itís the similar with my own music from my cds. When I put in a DVD no volume control shows up. How can I solve the following issues.
