Frequently asked questions
Question: Is it better to turn off my computer or put it in hibernation?
Answer: If you must quickly resume your work from a short break, hibernation is more convenient. For extended periods of inactivity, shutting down is better for saving power and preventing any file corruption.
Question: Should I put my computer to sleep or shut it down at night?
Answer: Shutting down at night saves energy and ensures a fresh start the next day. But, if you must quickly get back to your work in the morning, sleep mode can be more convenient.
Question: What is the difference between sleep and shut-down?
Answer:
- Shut Down: This is the power-off state. When you shut down your computer, all open programs close, and the Operating System shuts down. The computer uses almost no power in that state. However, when you turn it back on, you must wait for the boot-up process, which can take from a few seconds to a few minutes, depending on your computer.
- Sleep: In sleep mode, the computer enters a low-power state, keeping its current state in memory while other components shut down. When you wake the computer, it quickly resumes where you left off, with all running apps and open documents intact. The computer cannot stay in this state for long periods of time if it is using battery power, when the battery runs low the computer shuts itself off.
- Hibernate: This mode saves your computers current state to the hard drive, storing the contents of its memory to a file. When you power it back on, it restores the previous state from the hard drive to memory. Resuming from hibernate takes longer than from sleep, but it uses little to no power. A hibernating computer uses about the same amount of power as one shut-down.
Question: Can I turn off power supply in hibernate mode?
Answer: Yes, Hibernation saves your current state to the hard drive and then completely powers down the computer, using no power. When you turn the power back on, your computer resumes from where you left off.
