Neither really, not while using a p2p app, because a p2p app writes to the hard drive, and all suspend does it stop spinning the hard drive and power down anything unneccart.
I'd like to know why boyoh53 is so anti hibernation. To me its fine when i leave for longer than three hours expecting to come home right back to the comp, though lately i have been leaving it on for [email protected]
That's about the best you can do to conserve power. You can check the BIOS settings for your system to see if you have the option to power down the HDD after a set time period of inactivity too. That might save a few mW...but...unfortunately, computers use lots o' power these days.
