So I've got a version 1 macbook and back in april i decided to take it a part replace the thermal paste, clean out the dust, replace the wireless card, fix a problem with the ram slots and other general things. Anyway, i got it back together no problem but the speakers no longer work and i have 3 left over screws. Everything else is fine and I like to imagine it runs cooler but thats probably just me convincing myself. Now two of the screws come from the plastic shell since the little nut holders cracked a while back but one is of moderate length. If theres a diagram somewhere of the length and position of each screw that'd be a great help.
