Keep EDID data ADV748X only with 5V via HDMI connector

Dear Sir/Madam,

Can I keep ADV748X EDID data in EDID RAM if system only provides 5V power via HDMI connector, and the other power are all power down? 

If I can't keep those data with HDMI 5V, how would you suggest me to do in order to pass HDMI certification item (Test ID 8-1) which requires that EDID can be read after powering down for general case.

Thanks very much!

Henry
