When computers go into Sleep Mode, temporary files are stored in RAM for quick reawakening. At this moment, the computer only needs a weak electric current to stay hibernation. With Hibernate Mode, computers save files to their hard drive and minimize their power usage. Here are the results:Īccording to the data, computers on Sleep Mode and Hibernate Mode consume very little power and see no difference between them.īut actually, Hibernate Mode uses less power draw than Sleep Mode. We calculate the power consumption of the above computers in sleep, hibernation, and running state (CPU is idle) respectively with an electric energy meter. Monitor: Samsung SyncMaster E1920ENW/1920NW/E1920NWX.Hard disk: Samsung SSD 860 EVO 250GB ATA Device, ST500DM -1BD142 ATA Device.CPU: Intel(R) Pentium(R) CPU G640 Memory: Kingston HyperX KHX1866C10D3/8G.Hard disk: SanDisk SSD PLUS 240GB, TOSHIBA HDWD110.CPU: AMD Ryzen 3 2200G with Radeon Vega Graphics.The following is the basic hardware of three computers: We randomly selected three computers for the test. So how much power draw does a computer consume in these two modes? Read on to find more. The computers use much less power when they go into sleep mode or hibernate mode. When computers go into Hibernate Mode, all the files and programs running on the computer would be saved to the hard drive. ![]() Besides, all the work before entering the Sleep Mode can be running normally. Because when the computer is asleep, just a click of the mouse or a press of the keyboard can quickly wake up the computer. When we're away from our computers for a while, it's more convenient to set them on Sleep Mode. Normally the computer will go back to sleep after a scheduled task has been completed. Tasks that are scheduled but are not set to awaken the computer do not run. Sleep VS Hibernate: How much Power Consumption does a Computer Use? When asleep it will only run tasks that have been set to Awake the computer. ![]()
