Fujitsu Siemens monitor draws zero Watts in standby

How is this feat of engineering and environmental marvel achieved, we hear you cry? Easy, the power supply just turns itself off in power-save mode - it's as simple as that.
There's a switching element within the power supply to the monitor, that's controlled by the PC. When the screen's powered down, it also triggers the PSU to completely disconnect from the mains. The next time the PC sends an output to the monitor, a wee electrical signal restores the display's power to full glory.
Although this is great, it's at the same time quite sad that such an "invention" hasn't happened earlier, when saving energy and a green company logo wasn't considered important. The next hit for brand new PC's will probably be power supplies which can be turned off. Like they were, you know, 15 years ago.
