A password can be any combination of letters and numbers up to 16 character (a-
z, and 0-9). For security reasons, it is a good idea to use a strong password that
cannot be easily compromised. We suggest that passwords should follow these
rules:
• Strong passwords contain 7-16 characters, combine letters and numbers.
• Do not use your name or your user name.
• Do not use a common word or a common name.
• Be significantly different from your previous password.
Attention: Administrator and Power-On passwords are not case sensitive
Administrator Password
Setting an Administrator Password deters unauthorized persons from changing
configuration settings. You might want to set an Administrator Password if you are
responsible for maintaining the settings of several computers.
After you set an Administrator Password, a password prompt is displayed every
time you access the Lenovo BIOS Setup Utility program.
If both the Administrator and Power-On Password are set, you can type either
password. However, you must use your Administrator Password to change any
configuration settings.
