What's your typical "stand-by" mode for your computer when you're not using it?
I struggle with this for my personal computer. The TV-computer combo shuts off the monitor (triggers the tv to shut off when there is no input) after an hour. An hour after that it's suspended, works well.
My personal computer though, sometimes I shut off the monitor, most of the time I let it run for the day completely powered. I have yet to set any type of shutdown or standby because typically I use it more than I do my tv (work, gaming, videos, etc on the comp). I know there's some power conservation I need to consider for motivation, I have no security concern atm with my standard main account and everything private is layered so inaccessible.
tl;dr
what's everyone else's setup like for when they walk away from the computer?
I have hibernate enabled in windows, and have it set for when I click the power button on the case it hibernates instead of sleep or shutdown. Hibernation means it's off, but it saves its state before it shuts down and restores it after turning on. Meaning I have the convenience of my startup programs being all booted up and open windows and programs are just as I left them. I shutdown the computer normally the last time I use it at night, so I have it freshly booted in the morning.
Personally I hate waste and walking away from a computer for more than a few minutes and leaving it on makes me uncomfortable. I know I'm weird and a bit on the extreme side, but it's how I feel, and the hibernation option is a good option that keeps most of the convenience of leaving it on or suspended.
My understanding is that it's a difficult feature to support and they can't guarantee it works well. That's the only explanation I've ever seen, cause to me it's almost critical for working on a laptop.
