Erasing Lost or Forgotten Passwords
Note: To set a new password after completing this procedure, see Using Your
Personal Computer.
Your computer uses complementary metal-oxide semiconductor (CMOS) memory on the
system board for storing configuration and setup information. CMOS memory
maintains information about:
Ÿ
Date and time
Ÿ
Security features
Ÿ
Power-management devices
Ÿ
Storage devices
Ÿ
Keyboard and mouse
Ÿ
ISA legacy configuration information
Ÿ
Plug and Play configuration information
Ÿ
Port assignments
Ÿ
I/O addresses and interrupts
Ÿ
Other selectable features
Within the security features are the settings for the power-on and administrator
passwords. If you need to erase a lost or forgotten password, you must move a
jumper to clear CMOS memory.
Enhanced Security Information for PC 300PL Models
Some models have a new, Enhanced Security feature that provides extra
protection for your administrator password, as well as your startup sequence
settings. With Enhanced Security enabled, your administrator password and
startup sequence area stored in a highly-protected, nonvolatile, security
EEPROM module that is separate from CMOS memory and the EEPROM
module that stores system programs. When your administrator password and
startup sequence are locked in the security EEPROM, they remain intact even if
the battery in your computer expires or is removed by someone.
Be careful to keep a copy of your administrator password locked in a secure
place, because if you have this Enhanced Security feature and forget your
administrator password, your system will be unusable.
For more information on Enhanced Security, see Using Your Personal Computer.
