boot speed and standby power wasteboot speed and standby power wastePosted Sep 7, 2009 4:55 UTC (Mon) by eru (subscriber, #2753)In reply to: boot speed matters by drag Parent article: Debian switching to upstart In fact I would not be surprised that most modern appliances use current while "shut off". Not that I have done a survey. Yes, they do. And a lot. Plugging them into a power meter is eye-opening. For example a few years old Dell desktop PC I tested consumes 9 watts while supposedly "off", and my DTV set-top box seems to draw about the same amount, whether it is nominally "on" or "off". Google for "standby power waste" for more complaints... With CO2 reduction being the hot issue, authorities have started to look into this. EU and some other legislators have already set standby power limits that will gradually come into effect. A few years on, only consumer devices that are draw practically no current at all when "off" will be seen acceptable. For Linux to live on then, it either has to boot fast, or be reliably able to suspend into non-volatile memory.

Ever tried to plug that power meter on a laptop power supply without any laptop connected? Mine seems to consume 14 Watt all alone...
Long time ago there was good old voltage transformer made of steel, energy leaks were low, but now that is really different.
