Erasing a lost or forgotten password (clearing CMOS)
This section applies to lost or forgotten passwords. More information about lost or
forgotten passwords is available in Access IBM. If the user or administrator
password is lost or forgotten, you can regain access to the computer through one of
the following methods:
v
If you have forgotten the user password and an administrator password is set,
type the administrator password at the power-on prompt; then, start the
Configuration/Setup Utility program and change the user password (see the IBM
IntelliStation A Pro Type 6224 User’s Guide on the IBM IntelliStation
Documentation CD for more information).
v Remove the battery and then reinstall the battery (see “Replacing the battery” on
page 53).
v
Clear CMOS settings by changing the position of the CMOS recovery jumper
(JP1).
Complete the following steps to set the CMOS recovery jumper and erase a
forgotten password:
1. Read Appendix B, “Safety information,” on page 117 and “Handling
static-sensitive devices” on page 25.
2. Turn off the computer and all attached devices.
3. Disconnect the power cord.
4. Remove the cover and support bracket.
5. Locate the CMOS recovery jumper (JP1) on the system board (see Figure 4
on page 21), removing any adapters that impede access to the jumper.
6. Move the CMOS recovery jumper from pins 1 and 2 to pins 2 and 3.
7. Wait 60 seconds; then, return the CMOS recovery jumper to pins 1 and 2.
8. Replace any adapters that were removed; then, replace the support bracket
and replace the side cover.
You can now start the computer one time, and start the Configuration/Setup
Utility program, without having to use the power-on password. At this time, you
can either delete the old user password or set a new user password. If you do
not change or delete the password, the next time you start the computer the
original user password will be reinstated.
9. Connect the computer to a power source, keyboard, monitor, and mouse.
10. Turn on the computer. The Configuration/Setup Utility program starts.
11. Follow the instructions to erase the existing password or create a new
