Disabling a Forgotten Password
The system's software security features include a system password and a setup password, which are
discussed in detail in
"Using the System Setup Program
" on page 29. The password jumper enables these
password features or disables them and clears any password(s) currently in use.
CAUTION: Only trained service technicians are authorized to remove the system cover and access any of the
components inside the system. Before performing any procedure, see your Product Information Guide for
complete information about safety precautions, working inside the computer and protecting against electrostatic
