"Hibernate" is not, as the build in flash is to small, but nothing stops iRex or any third-party hacker from implementing it with a memory card. "Standby" is what the iLiad does between key presses, although it is not yet complete.

What the iLiad can not do is "Suspend to RAM", that is Standby + disabling the CPU, so the only components that would still consume power would be the RAM, the realtime clock, the memory controller and the keyboard controller. There simply are no memory or keyboard controllers (as I understand), so the CPU must do that work.

However, I'd guess the difference in power consumption between dedicated memory plus keyboard controllers and the CPU in 33Mhz mode is not very big.
Hi folks.

Hoping that anyone involved still reads this thread, I'd like to ask a question to that respect:
What about the power switch?
It doesn't seem like a physical power switch, but rather seems to generate an event (e.g. triggering iliad shutdown). If it is able to start a completely shut down device (without running CPU), what's stopping it from waking a suspended one up?
Does anyone know what this lever is controlled by, and whether it could serve that purpose?

Cheers.
