Clearing and Resetting the CMOS

The computer’s configuration memory (CMOS) stores information about the computer’s configuration. The CMOS jumper resets CMOS but does not clear the supervisor and user passwords.

1.Turn off the computer and any external devices, and disconnect the power cord from the power outlet.

2.Disconnect the keyboard, monitor, and any other external equipment connected to the computer.

WARNING! To reduce the risk of personal injury from electrical shock and/or 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 computer is plugged in, the power supply always has voltage applied to

the system board even when the unit is turned off. Failure to disconnect the power cord can result in damage to the system.

Static electricity can damage the electronic components of the computer or optional equipment. Before beginning these procedures, ensure that you are discharged of static electricity by briefly touching a grounded metal object

3.Remove the computer cover or access panel.

CAUTION: Resetting the CMOS jumper will reset CMOS values to factory defaults. It is important to back up the computer CMOS settings before resetting them in case they are needed later. Back up is easily done through Computer Setup.

4.Locate the header and jumper.

NOTE: For assistance locating the CMOS jumper and other system board components, see the Illustrated Parts & Service Map (IPSM) for that particular system. The IPSM can be downloaded from http://www.hp.com/support.

CAUTION: Make sure you have disconnected the AC power cord from the wall outlet. Clearing the CMOS while power is connected can damage the system board.

5.Remove the jumper from pins 1 and 2. Place the jumper on pins 2 and 3.

6.Place the jumper back on pins 1 and 2.

7.Replace the computer cover or access panel.

8.Reconnect the external devices.

9.Plug in the computer and turn on power.

NOTE: You will receive POST error messages after clearing CMOS and rebooting advising you that configuration changes have occurred. Use Computer Setup to reset any special system setups along with the date and time.
