Hi,

I've just posted a Stable draft of the PWG Power Management Model:

 ftp://ftp.pwg.org/pub/pwg/wims/wd/wd-wimspower10-20100922.pdf / doc
 - clean copy with line numbers

 ftp://ftp.pwg.org/pub/pwg/wims/wd/wd-wimspower10-20100922-rev.pdf / doc
 - redlines with line numbers

This draft addresses all the comments from the Samsung prototypes and the
August PWG F2F.

This document is technically aligned with PWG Imaging System Power MIB.

Comments?

Cheers,
- Ira
