Law Firm Investigating Powerbook RAM Problems for Class Action

We’ve heard many times that Apple Powerbooks are finicky about RAM (and that may be true), but it would appear that for owners of 15-inch Powerbooks, it might not be the memory that has the problem after all. A law firm is investigating claims that a fairly recent version of Mac OS X corrupted the firmware in the memory controller inside Apple Powerbooks, rendering the lower of two memory slots unusable.

If you’ve had a problem with your 15-inch Powerbook, you’ll probably want to fill out their form to get a potential piece of the class action. Judging from the Engadget, Powerbooks under warranty can have the problem fixed by replacing the logic board.
