Apple has a page on their support Web site detailing how to properly care for a PowerBook that is required reading for all PowerBook owners – because most people never even touch the manuals. It’s mostly obvious stuff like “Avoid getting moisture in any openings” and “Do not spray liquid directly on the screen,” etc. but there are a couple of gems in there, like “Always leave space around your power adapter. Do not use this equipment in a location where airflow around the power adapter or computer is confined.” This is spot on. My 65 watt AC adapter got solar hot recently when it was wedged between the pillows on my couch for about an hour.
One they forgot to add: “PowerBooks don’t like coffee.”
