Tried to upgrade BIOS to v1.20 as provided by Acer
The things chaged a little :
uplug from AC, wait for suspend, replug AC, press a key to wake : now after text console blink, appears a black console showing display brightness indicator ! But the rest is still the same : no response to keyboard or network, the only way out is power-cycle.
Beeps are still heard on AC unplug/replug.
