PC can be put to sleep by choosing the desired option from the Windows Power Menu while closing the laptop lid puts it to sleep automatically. Additionally, Windows computers can be configured to automatically fall asleep after a set idle time to save power. To wake up the system from sleep and get back to action, simply move the mouse around or press any key on the keyboard.

Note: Replace the CALLER_TYPE as PROCESS, NAME as chrome.exe, and the REQUEST to EXECUTION so the command would be powercfg -requestsoverride PROCESS “chrome.exe” EXECUTION as illustrated below.
