Clearing and Resetting the CMOS
The CMOS of the workstation stores password information and information about the workstation
configuration. This section describes the steps necessary to successfully clear and reset the CMOS.
Using the CMOS Button
Follow the steps below to clear CMOS using the Clear CMOS button:
WARNING! To reduce the risk of personal injury from electrical shock and hot surfaces, be sure to
disconnect the power cord from the wall outlet and allow the internal system components to cool before
touching.
CAUTION: When the workstation is plugged in, the power supply always has voltage applied to the
system board even when the workstation is powered off. Failure to disconnect the power cord can result
in damage to the system
CAUTION: Static electricity can damage the electronic components of the workstation or optional
equipment. Before beginning these procedures, be sure that you are discharged of static electricity by
briefly touching a grounded metal object.
1. Shut down the operating system, and then power off the workstation and any external devices.
Disconnect the workstation power cord and any external devices from the power outlets.
2. Disconnect the keyboard, monitor, and any other external devices that are connected to the
workstation.
3. Remove the access panel.
CAUTION: Pushing the Clear CMOS button resets CMOS values to factory defaults and erases
any customized information, including passwords, asset numbers, and special settings. It is
important to back up the workstation CMOS settings before resetting them in case they are
necessary later. To back up the CMOS settings, use the Computer Setup (F10) Utility and
select Save to Diskette from the File menu.
4. Locate, press, and hold the CMOS button for five seconds.
NOTE: Be sure that the AC power cord is disconnected from the power outlet. The CMOS button
does not clear CMOS if the power cord is connected.
NOTE: For assistance locating the CMOS button and other system board components, see
System board components on page 59.
5. Replace the access panel.
6. Reconnect any external devices.
7. Plug in and power on the workstation.
NOTE: The workstation passwords and any special configuration information, including the
system date and time, must be reset.
The workstation powers up for three to five seconds, then powers down.
