The mode that is not present in the 'Shut Down' menu of the Start Button is the "Log in" mode.
Here's a breakdown of the options and their presence in the 'Shut Down' menu:
- Hibernate: This mode saves all open documents and programs to the hard drive and then turns off the computer. When the computer is turned on again, it restores the system to its previous state.
- Sleep: This mode puts the computer into a low-power state, allowing it to quickly resume full-power operation when needed. It saves all open documents and programs to memory.
- Log in: This mode is not present in the 'Shut Down' menu. It refers to the action of entering your credentials to access the computer or a user account.
- Lock: This mode allows you to lock the computer without shutting it down, so that you can protect your work and prevent unauthorized access.
In summary, the 'Shut Down' menu of the Start Button does not include the "Log in" mode.
