Passwords
As many as two passwords may be needed for any Lenovo IdeaPad computer:
the power-on password (POP) and the supervisor password (SVP).
If any of these passwords has been set, a prompt for it appears on the screen
whenever the computer is turned on. The computer does not start until the
password is entered.
Exception: If only an SVP is installed, the password prompt does not appear
when the operating system is booted.
Power-on password
A power-on password (POP) protects the system from being powered on by an
unauthorized person. The password must be entered before an operating
system can be booted.
Supervisor password
A supervisor password (SVP) protects the system information stored in the
BIOS Setup Utility. The user must enter the SVP in order to get access to the
BIOS Setup Utility and change the system configuration.
Attention: If the SVP has been forgotten and cannot be made available to the
servicer, there is no service procedure to reset the password. The system board
must be replaced for a scheduled fee.
Power management
Note: Power management modes are not supported for APM operating system.
To reduce power consumption, the computer has three power management
modes: screen blank, sleep (standby), and hibernation.
Screen blank mode
If the time set on the “Turn off monitor” timer in the operating system expires, the
LCD backlight turns off. You can also turn off the LCD backlight by pressing
Fn+F2.
To end screen blank mode and resume normal operation, press any key.
Sleep (standby) mode
When the computer enters sleep (standby) mode, the following events occur in
addition to what occurs in screen blank mode:
• The LCD is powered off.
• The hard disk drive is powered off.
• The CPU stops.
To enter sleep (standby) mode, press Fn+F1.
In certain circumstances, the computer goes into sleep (standby) mode
automatically:
