PB 1400 PMU Updater 1.0.1

We previously reported on an Info Alley description of a brightness/contrast problem with the PowerBook 5300/190 and (possibly) on some other 5300 and 1400 models. The article said that Apple was working on an update.

Now, Apple has posted a file that, according to the ReadMe, fixes a separate brightness/contrast problem - where the controls for brightness and contrast operate incorrectly - specifically for the 1400: PB 1400 PMU Updater 1.0.1. Apparently, the promised update for the 5300 problem is still in the works.
