Can OSX still do maintenance if the powerbook or ibook when the lid is closed?

no, everything is put into a frozen state. the nightly/monthly/weekly maintenence cannot be done during that time. if you download Cocktail (http://www2.dicom.se/cocktail/index.html) you can make your machine run this maintenence on demand.
