WARNING! To reduce the risk of personal injury from electrical shock and hot surfaces, 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 has voltage applied to the system board, even when the computer is powered 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, be sure that you are discharged of static electricity by briefly touching a grounded metal object. 1. Shut down the operating system, power off the computer and any external devices, and then disconnect the computer power cord and external devices from power outlets. 2. Disconnect the keyboard, monitor, and other external devices that are connected to the computer. 3. Remove the access panel. CAUTION: Before pressing the Clear CMOS button, back up your computer CMOS settings. Pressing the Clear CMOS button resets CMOS values to factory defaults and erases customized information, including asset numbers and special settings. To back up the CMOS settings, run 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: Verify that the AC power cord is disconnected from the power outlet. The CMOS button does not clear CMOS if the power cord is connected. For assistance locating the CMOS button and other system board components, see the system board layout in the Replacing components section. 5. Replace the access panel. 6.
