Sleep Mode Power Consumption?
Hi all,
I've recently upgraded to Vista and have started using it's sleep mode instead of switching my pc off at night. It starts up much quicker this way.
How does the power consumption differ? By switching off my pc i mean it's off, but still plugged in and switched on at the wall socket - so that the lights on the mobo stay on.
Specs:
Abit IP35 mobo
E6750
320GB HDD
2gigs ram
ATI X1950GT

My PVR machine, a ibase itx mobo with a p4 mobile cpu, draws almost as much power in sleep as idle! (since sleep keeps most of the motherboard running). I now use Hibernate, which effectively uses the same power as 'off'.
It might be a good idea to borrow a power meter or current meter to measure the pc's actual useage.

Most of our motherboard reviews measure power consumption under Vista with the system off and idle - the difference is always 1W. All the systems I've tested at home are about the same, including mine which has an overclocked E8400, 4GB of RAM, and 8800GT.Bobendren wrote: A power meter would be a good idea, but that would involve money and/or
effort. I was hoping someone here had already done some testing
for those who don't measure a difference between idle and sleep, the computer most likely is entering S1 standby instead of S3 standby, the latter of which switches off nearly all components but RAM and some other stuff needed for wake-up from S3. S1 is quite useless from the power consumption reduction perspective (in fact, I have still to figure out from which perspective it isn't useless).
