Turn power off, then on to reboot. Clearing CMOS Using Computer Setup The computer's configuration (CMOS) stores password information and information about the computer's configuration. To clear and reset the configuration, perform the following procedure: ✎ This is the preferred method for clearing CMOS. However, if you cannot access Computer Setup, refer to the next section for instructions on using the CMOS switch to clear CMOS. 1. Turn on or restart the computer. If you are in Microsoft Windows, click Start > Shut Down > Restart. 2. As soon as the computer is turned on, press and hold the F10 key until you enter Computer Setup. ✎ If you do not press F10 at the appropriate time, you must restart the computer and press and hold F10 until you enter Computer Setup. 3. Use the arrow keys to select Load Optimized Defaults, then press Enter. 4. To apply and save changes, press F10, or select Save & Exit Setup and press Enter. Clearing CMOS Using the CMOS Switch The computer's configuration (CMOS) may occasionally be corrupted. If it is, it is necessary to clear the CMOS memory using switch SW2. To clear and reset the configuration, perform the following procedure: 1. Prepare the computer for disassembly. Ä CAUTION: You must disconnect the power cord from the power source before sliding the Clear CMOS switch (NOTE: All LEDs on the board should be OFF). The CMOS switch will not clear CMOS if the power cord is connected. 2. Remove the access panel. 3. Slide the CMOS button located on the system board and hold it for 5 seconds. 4. Replace the access panel. 5. Turn the computer on and run F10 Computer Setup (Setup Utility) to reconfigure the system. Disabling or Clearing the Power-On and Setup Passwords 1. Turn off the computer and any external devices, and disconnect the power cord from the power outlet. 2. With the power cord disconnected, press the power button again to drain any residual power from the computer. 3. Remove the access panel. 4. Locate the header and green jumper labeled J5. 5. Remove the jumper from pins 1 and 2. Place the jumper over either pin 1 or pin 2, but not both, to avoid losing it. 6. Replace the access panel. 7. Plug in the computer and turn on power. Allow the operating system to start, which clears current passwords and disables the password features. 8. To re-enable the password features, repeat steps 1-3, then replace the jumper on pins 1 and 2. 9. Repeat steps 6-8, then establish new passwords in Computer Setup. Refer to the Computer Setup (F10 Setup) instructions to establish new passwords.
