Should You Shut Down, Sleep, or Lock Your Computer?

It’s a common question: Should I shut down my computer every night, just let it sleep, or simply lock it? The answer depends on how you’re using your system — and your goals for speed, security, and power saving.

Here’s a breakdown of your options:

🔒 Lock (Keep it On, Just Secure It) 

Use this when you’re stepping away briefly and want to keep everything open but prevent unauthorized access.

• Your session stays active

• Apps stay open

• Screen is hidden behind a login screen

  Important: This only works if you’ve set a password for your account — otherwise, it doesn’t actually protect anything.

On Windows: Windows + L

On Mac: Control + Command + Q

💤 Sleep Mode (Low Power, Fast Resume) 

Perfect if you’re done working for now but plan to come back later.

• Saves your session to memory

• Uses a small amount of power

• Wakes almost instantly

  Great for laptops and desktops alike.

⏹ Shut Down (Fully Powered Off) 

Best if you won’t use the machine for a while, or if it’s acting slow or glitchy.

• Closes all apps

• Clears out system memory

• Helps install updates cleanly

  We recommend a full shutdown at least once a week to keep performance smooth.

Bottom line: 

• Lock it for security when you walk away

• Sleep it for convenience if you’re coming back soon

• Shut it down for a clean slate or when you’re done for the day
