To drive this idea further: Maybe Apple has already left a surplus range to
higher brightness in terms of power rating of the components used. We might
be able to simply replace a resistor or add another one in parallel to
improve the brightness after it started to fade.
As I connected 12V to one of my Newtons its BL became suddenly much
brighter. This means to me that the drive is a non-regulated one and simply
drives a pre-settled current into the BL foil capacitance. The power
transistor is certainly under dimensioned :-) Thus the remaining question is
where it is located.
