I still have the system lag on most boots until after a sleep cycle (sometimes its ok straight away, no reason or rhyme to it).
The battery icon was available earlier but following a reboot won't stick around when enabled.
Audio output via internal speakers
but System Preferences shows No Trackpad Found - Fixed with SmartTouchpad v4.6.5
USB3 Works (recognised)
Wake from 'sleep' (see below)
SD card slot (recognised)
Sleep puts the machine to sleep but it wakes a second or 2 later with a black screen, sits there for a while with fans spinning then auto sleeps again and repeats.
The hardware buttons (Wifi, volume up/down/mute) work but also function as eject at the same time.
