Passwords and sleep (standby) mode
If you have set passwords and you put your computer into sleep (standby) mode by pressing Fn+F4, the
procedure for resuming operation is as follows:
• You are not prompted to type the password when resuming operation.
• If any hard disk or the solid state drive has a hard disk password, it is unlocked automatically when
you resume operation.
Using Passphrase
When the Passphrase function is enabled, you can set a power-on password, hard disk passwords, and a
supervisor password, each containing up to 64 characters.
Enabling the Passphrase function improves the protection of the hard disk password and thus improves
the security of your computer.
The Passphrase function is enabled by default.
For more information about using the Passphrase function see the following sections.
