You don't use Hibernate?
I know you're not responding to me but...
Is there a reason to use hibernate considering the loss of ssd space and risk?
Considering how cheap ram is these days, many of us have 16-32 gb of ram and only a 128-256 ssd so that's a sizable chunk.
I remember reading that if you do the math, and if your pc supports S3 sleep, it costs ~25c extra a month to leave your pc on 24/7 assuming you use it daily. Which is acceptable to me and is worth it since I often use WOL to access my pc.
The actual cost for would depend on local electricity prices and time that the system is in use vs sleep/off.
From a study that Microsoft did, it looks like sleep uses 3-4W vs. 0.5-2W for off. So let's say we save roughly 2 watts/hr powering off instead of using S3 sleep.
At 16 hours of non-use time per day, that's 496 hours per month, for just under 1kw in savings. Electricity is about $0.10 per kwh where I live, but for some parts of the country it is quite a bit higher.
Even in the worst parts of the country, where top-tiered usage in California nets you $0.45/kWhr...you're only looking at saving enough for a McD's Happy Meal over a year.
