Erasing Lost or Forgotten Passwords
Note:
To set, change, or delete a password, 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:
Date and time
Security features
Power-management devices
Storage devices
Keyboard and mouse
ISA legacy configuration information
Plug and Play configuration information
Port assignments
I/O addresses and interrupts
Other selectable features
Important
Clearing CMOS memory erases the configuration of your computer. Because
you need to reconfigure the computer after clearing CMOS memory, record the
configuration information of your computer before altering the CMOS jumper.
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 erase all of
the configuration and setup information by moving the jumper designated for
CMOS memory.
To locate the CMOS-clear jumper, see “Identifying Parts on the System Board” on
page 7 or see the label on the underside of the computer cover. On the cover label,
the jumper is referred to as the password jumper.
