PROBLEM: Review: I bought this to replace the supposedly same power adapter that I purchased last year. This is NOT the same adapter as pictured for the item (I see that a customer has added two pictures of the true product). I was not concerned with this difference but would have preferred to have a light indicating the power is on. At first, it seemed to power my powerbook G4 fine, but later it started to cycle as charging and not charging, thus making the screen brighten and darken. When I shut the computer and let it charge, it did charge some, but I'm concerned about ruining my battery (which is also a replacement). It simply does not work when you are using the computer..and I'm ALWAYS using my computer! I will have to find an alternative to this product. I thought it was bad enough that the one I got last year quit working, but this is ridiculous. 
 Polarity: Positive

SOLUTION: False

PROBLEM: Review: This book really should be removed from circulation. While basic MIDI information is in there, it is so out of date it just makes it hard to read. Examples are of obsolete or vintage gear and has no real relation to todays musician.Illustrations are all cheesy and look like bad microsoft clipart. Photographs are all poor and dated. The section on MIDI and a personal computers lists atari and commodore as possible good choices - get the picture!If you are looking for charts of Control codes etc, - they are in here, but you can find those anywhere. If you are trying to get information on MIDI in the last decade or so, buy a different book.
