Dear all, What will be power consumption of a computer i.e. whether it will consume any power after we switch-off the monitor, eventhough the CPU is still on. Regards.
I read something that disagreed with this, but I'm too lazy to look. If I remember correctly, black and white LCD pixels have the same or nearly the same power requirements, and the 'screen backing light' has a much greater effect.
Even if the monitor is switched off, your computer will consume power. The amount depends on what you've got inside - processor, graphics card, hard disk, cooling fans etc.. This can give a rough idea of how much power is consumed.

"Blackle" doesn't really work with LCD monitors. Old CRT monitors do draw less power when they display a black instead of a white screen, but an LCD screen works totally differently and displaying a black instead of a white screen doesn't make any difference for the amount of power it draws.
If you really want to know how much power your computer draws, you could buy a power consumption monitor device to measure it.

Hmm... and probably LCD screen draws MORE power to go black? [ December 17, 2008: Message edited by: Akhilesh Trivedi ]
