Hi Gabor

> How do you switch them off? My understanding is that HDMI is powered down if I don't use it. I don't have anything connected but the serial header.

Sure but that is zero guarantee it is not in use. Check dmesg for TDA19988 (the HDMI framer chip). Again you will need to do some research but I think I2C tools can be used to put the framer into low power mode.

As far as PMIC is concerned my knowledge is limited. Suggest having a look here: http://andicelabs.com/beaglebone-powercape/ as these guys know all about power management on the B3
