Notebook power scheme settings

I'm not sure on some of the settings so I'd like to ask what you think:

Normally I run portable/laptop scheme, except that I have system standby disabled, because it disconnects the network (I'm guessing there is an option to have the network not turn off)?

Turn off hard disks: Does anyone use this? I never used this on a desktop. When the drive turns off, does this interfere with any i/o functions like copying files? (I'm assuming the drive turns off after x-minutes of not touching the mouse pointer). Does this really prolong the life of the drive/battery?

Hibernate: Pretty much same as above. Does it interfere with disk access? Does anyone use hibernate?

Thanks!

 

In standby you can have your network bring you computer back if there is activity, just go the the System Properties, then Device Manager, find you network card, and there is an option for it. That might help your problem with standby.

Turn off hard disks would be good if you are on battery, or good just so you don't wear your disk out. Basically, if the computer isn't used, they will spin down to save power and wear. When you need something, they spin right back up and off to work you go. I use it, but I have never tested to see how much of a battery life difference it makes.

Hibernate is a good feature. Basically, it allows you to shut your computer off, but leave programs and documents open, and return to work as soon as you turn your computer on. Its faster that a Shut Down/Normal Boot, and it is safer and more power efficient than standby. Because you computer is off, you won't have disk access, so I would say it would interfere.
