WINDOWS 10 POWER SLEEP VS HIBERNATE PC
This uses very little power, your PC starts up faster, and you’re instantly back to where you left off. Note that OLD PCs don't have a hibernate option. Now you'll be able to happily hibernate your PC. Under Shutdown settings, select the Hibernate checkbox (if it's available), and then select Save changes. Select Choose what the power button does, and then select Change settings that are currently unavailable.In the search box on the taskbar, type power options, and then select Power Options.You can do this easily with CMD( Run as Admin) by typing in: powercfg/h on There IS an option for Hibernate, you just have to enable it. Otherwise, if Hibernation is available, then go with it. TL WR: If you follow the steps below and Hibernate won't enable, then you should shut down your PC. Having the RAM powered in sleep state is not expensive, as the RAM is not in active use – only the memory has to be retained. However, I put my computer into hibernate mode and the power consumption dropped by 1 watt (compared to sleep). If you pay 16 cents per kWh, that's 15 dollars per year (if you left your PC in sleep for the whole year). For comparison, that's probably two phone chargers worth of power. I tested my computer for sleep power consumption - 0.047A at 251VAC which means about 12 watts. Hibernation will also shut down the RAM and depending on the computer, your USB devices may receive power. For example, my USB mouse will turn its lights off when my computer sleeps, but I can still press a mouse button to wake the PC.Īll the power hungry parts of your PC will stop functioning under sleep, and they also do so in hibernation. The USB devices will either go into a sleep mode as well, or continue operating. Sleep mode will keep the RAM and usually all of your USB devices powered.
