Computer Shuts Down Instead Of Sleeping | Fix

Some times When we attempt to put computer on "sleep" it appears to shut down. i.e. you may have to start the computer from the power button rather than click the mouse computer will not sleep.

But, before you try to fix this issue, you need to check your keyboard whether the keyboard or mouse has an option to wake the computer up when its in sleep mode.

To fix your issue, you need to open a command prompt with administration rights and issue a command.

1) Search for "CMD"

2) Right click "CMD" and "Run as Administrator". If you were asked to enter the administration password, give the required.

3) In the command line, type in "powercfg.exe /hibernate off"

Sleep should work properly now, instead of shutting off your PC. Watch the below screen shot for any help.

The ability to recover from sleep mode by pressing a key on the keyboard or by moving the mouse on a computer that supports ACPI is dependent on the computer's motherboard. This ability is disabled in older Intel motherboards, and the only way to wake the computer from sleep mode is to press the Power button.

With most newer motherboards, you can wake the computer by pressing the Power button, by pressing a key on the keyboard, or by moving the mouse.

ACPI support is necessary to take full advantage of the power management and Plug and Play features in Windows. If you are not sure whether your computer is ACPI-compliant, please see the printed documentation for your computer or motherboard, or contact the manufacturer of your computer or motherboard.
