I have also noticed that the lid-off message when entering firmware does not ever happen on the XO 1.5. Consistently on all machines, whether I do a shut-down or a restart from Linux the screen goes to text console, (last message ; dcon freeze) then goes to the warning screen, then goes blank. Then on the 1.5 whether doing restart/reboot from Linux or doing a shut-down, the power light blinks multiple times before strating up again. However, on the XO 1.0 when doing a shut-down, the power light blinks before turning completely off, but when doing a Linux restart, the power light does not blink at any point in the restart process.
