When connecting to external the monitor seems to detect something but then says no HDMI connection - so seems as though some sign of signal from HDMI connector but definitely not booting. NO chime. THis does SMC reset. Hard to tell if it is PRAM resetting.
Turning on:
Power button, 2 seconds later = fan spin, about 12 seconds after power-up fan pauses for about 3 seconds, then spins again for about 10 seconds and pauses for 3 and repeats.
Reflash the firmware?
