![]() ![]() This option was designed for laptops and might not be available for all PCs. Check the documentation that came with your computer or go to the manufacturer's website. You might be able to wake it by pressing any key on the keyboard, clicking a mouse button, or opening the lid on a laptop. On most PCs, you can resume working by pressing your PC's power button. When you’re ready to make your PC sleep, just press the power button on your desktop, tablet, or laptop, or close your laptop’s lid. Repeat for the Plugged in column, if desired.

To set your PC so it goes to sleep when you close the lid or press the power button: Use Sleep when you’re going to be away from your PC for just a little while-like when you’re taking a coffee break.įor a lot of PCs (especially laptops and tablets), your PC goes to sleep when you close your lid or press the power button. You don’t have to worry that you'll lose your work because of your battery draining because Windows automatically saves all your work and turns off the PC if the battery is too low. Sleep uses very little power, your PC starts up faster, and you’re instantly back to where you left off. The third step commences if the PC remains undisturbed in hybrid sleep for long enough: The sleep mode portion terminates, and the PC then enters full, standard hibernation.To shut down, select Start and then select Power > Shut down. This way, the PC can wake up instantly (like standard sleep) but with the robustness of hibernation, in that a power-loss or total shut down won’t cause trouble (because all data is safely stored in the hibernation file on the hard drive). But in the second step, instead of shutting down completely, the PC then goes into sleep mode. ![]() First, when hybrid sleep commences, the system prepares as if it were going to hibernate the RAM and CPU contents are fully written to the hard drive. Hybrid sleep combines standard sleep and hibernation in a three-step process. Hibernation is more robust than sleep because the PC is totally off: Even if you unplug the PC or remove its battery, the data is safe on the inert hard drive. But when the PC fully re-awakens, it can pick up from where it left off. ![]() Because this usually involves manipulating several GB of data, this process is not instantaneous - it usually takes at least a few seconds. When a PC awakens from hibernation, Windows uses the contents of the hibernation file to put the system RAM and CPU back into the exact state they were in when hibernation began. Hibernation writes the entire contents of RAM and the exact state of your PC’s CPU into a hidden hibernation file on the hard drive then the PC shuts off completely. The downside to standard sleep is that if anything interrupts the power supply to the sleeping PC, the contents of RAM (including any unsaved files) will be lost, and the PC will not be able to resume normally upon wake-up. The major advantage of standard sleep mode is that, when the PC wakes up, it can pick up from where it was almost instantly. In sleep mode (sometimes called suspend), your PC goes into a low-power state, consuming just enough electricity to keep the RAM contents intact to monitor for system events (such as a key- or mouse-click, or closing the lid on a laptop) and to run similar low-power processes. ![]()
