When you step away from your computer, turning it off helps save the most energy. This action closes all active apps and documents, as well as shutting down the operating system. The drawback is the time it takes for the system and startup programs to load again. Powering off is the ideal choice when you’ll be away from your laptop for an extended period. Keep in mind that restarting your computer is equivalent to powering it off, but instead of remaining off, it immediately turns your laptop back on.
Placing your computer in sleep mode puts your laptop into a low-power state, as only the open apps and documents continue to use power while the rest of the system remains idle. This option enables you to return to your computer and find everything exactly as you left it. Sleep mode is best suited for short breaks, such as when you need to step away briefly but will return shortly.
Opting for hibernation mode saves your open apps and documents to the computer’s hard drive, allowing you to pick up where you left off when you power up your laptop. Hibernation takes longer to start up compared to sleep mode, but it conserves more battery life. This mode is most appropriate when you’re done using your laptop for the day and plan to resume work the next morning or afternoon.
