amazing engineering in there. My local repair guy had it apart for my 2nd keyboard replacement.

There is a lot of work in getting the top off the base of the computer. A number of visible and hidden screws (under memory slots) hold this together. Definetly nothing as simple as the Ti books.

Anyways, under the keyboard, you will find MANY fiber optic strips. The light source is placed on one end of the keyboard, which pipes light though the optics. Harddrive sits under the touchpad...processor is at the top middle, under the 6,7 key areas. The cooling fans push air from the top sides where the esp and eject keys are located. The airport has a coax cable antennae that runs through the hinge into the lcd pannel. Next to the speakers are the tiny ambient light sensors which activate the lgihted keyboard, so you could just block those on the underside of the speaker grills if you wanted 100% lighted keyboard action.

Thats about all I can remember now. BTW, the keys on my keyboard that wouldnt light up, the damn apple QC guy didnt even check see that there was black TAPE ON THE UNDERSIDE OF THE KEYS WITH NO LIGHT...DUH! all we had to do was pull them off.

Any chance of you remembering whether the right speaker is slightly blocked by something? I've noticed that PB15 speakers appeared to be slightly left biased. I had thought it may had to do with the way the speakers are physically positioned.

I cant remember 100% but one speaker is positioned lower in the grill than the other. Also, one speaker appeared to be pysically LARGER than the other. This might cause the difference you are hearing.

I noticed that aswell....One of the first things I noticed when I got it. I am planning on buying some speakers though

On my 12" and 17" powerbooks the sound goes out of center on its own. Go into system preferences and balance the sound to center. If you still feel it is not centered, just move the position toward the lacking direction.
