Close powerbook without sleep?

set it so that it stays awake when it¹s closed so I can have it perform time-intensive jobs during my commute

Ive got a 15d G4 TiBook. Before that I had an old powerbook duo. With the duo, at the end of the day I could set it up to perform some labor-intensive activity (like running a macro on a database) while it was in my briefcase during my commute home.

The TiBook goes to sleep as soon as I close it. It there any way I can set it so that it stays awake when its closed so I can have it perform time-intensive jobs during my commute to and from work?

Even if you can figure a way to do it, it's a very bad idea. Heat is dissipated through the keyboard. Closed TiBook + closed briefcase = fried screen.

On the other hand, the Powerbook G4 can run closed with an external monitor & keyboard http://docs.info.apple.com/article.html?artnum=88064.
