Q:
How much power does the PCMCIA Expansion Module draw from my Apple Powerbook?
 
A:
Idle with no cards: .460 mA...less than 1 milliamp.

Operating with cards: Typical is 56mA plus inserted cards power draw. Maximum is 58mA plus inserted cards power draw.\

The cards can vary from 150mA for modems to 600mA for rotating media. (New ExCA spec is trying to limit cards to 300mA.) Also, some cards have very high peak requirements (spinning up drive).

The PowerBook 500 series PDS connector is rated at 600mA continuous for the entire PDS module.
