IBM THINKPAD A20M

Using password
Supervisor password
The supervisor password protects the system information stored in
the IBM BIOS Setup Utility so that, without knowing the password, no
one can change the configuration of the computer.
Attention
If you forget your supervisor password, there is no way to reset it.
You must take your computer to an IBM reseller or marketing
representative to replace the system board. A fee will be
charged for parts and service.
To establish a setup password, refer to the online user's guide.
Network password
If you work on a local area network (LAN) with your ThinkPad
computer, your LAN administrator might have set passwords to
restrict access to various parts of the network. If you are authorized
to access restricted areas of your LAN, you will need to establish a
logon password in Windows.
To establish your network password in Windows, refer to the online
user's guide.
Passwords and standby mode
If you have set passwords and you put your computer into standby
by pressing Fn+F4, you can resume operating the computer by
pressing the Fn key.
You will be prompted to type your password. To unlock your
computer, you must enter a power-on password or a supervisor
password (if one is set).
If one or more hard disks has a hard-disk password, the disks are
unlocked automatically when you resume your computer.
For information on hard-disk passwords with a hard disk in a docking
station, refer to the online user's guide.
