The LCD consumes zero power when the DM42 is switched off. It's a Sharp "Memory LCD". The 5V booster required to supply the LCD is actually switched off altogether when the DM42 is switched off.

Interesting...
Of course I would expect the 5V booster to be switched off when the machine is in off state.

However, I understand the Shard LCD requires power to maintain the Off image, as it is stored internally to LCD the memory cells (1 cell per pixel).

If you remove the battery cell and short the battery holder contacts for a few hours, will the Off image retained and visible on the LCD display?
