WinSleep by MollieSoft - free download

WinSleep keeps your computer asleep (while not too busy) as much as possible during periods you specify. Provides a detailed time-line graph showing when your computer was awake, asleep, or hibernating. Provides convenient Sleep and Hibernate buttons for manual use when desired. Shows the current CPU/Disk/Network usage percentages for your computer. Runs on Windows 8.1 or Windows 10. Saves money! A typical desktop uses 250 watts of electricity when awake, but only a few watts while asleep. Power companies (in the US) may bill at say 10 cents per kWH. This is .25 kWH @ 10 cents = 2.5 cents/hr you are saving while asleep. Say WinSleep sleeps your computer for half the day; this is $.30/day = $109.50 per year. The more you sleep, the more you save. (We didn't even count the power consumption of the computer monitor here.) Helps prolong the life of your desktop computer. Your disk drive is not spinning, motherboard is not powered, fan is not running (and accumulating dust inside the computer casing), and your monitors are in standby mode.
