Turn off the computer and any external devices, and disconnect power. 2. Remove the access panel. 3. Locate the light green CMOS jumper header on the motherboard. It is labeled CMOS. 4. Remove the jumper from pins 1-2 pins and put it on pins 2-3 to clear CMOS. Keep the cap on pins 2-3 for 5 to 10 seconds. 5. Replace the jumper on pins 1-2. 6. Reinstall the battery. 7. Replace the access panel, external devices, and reconnect the power cord. 8. Turn on the computer. 9. Hold down the F1 key during boot and enter BIOS setup to re-enter data. Clearing System Passwords To clear passwords: 1. Turn off the computer and any external devices, and disconnect power. 2. Remove the access panel. 3. Locate the light green password jumper header on the motherboard. It is labeled PSWD. 4. Remove the jumper from pins. 5. Plug the computer in and turn on power. 6. When you see the HP logo screen, turn off the computer. This clears the current passwords. 7. Replace the jumper to its original position. 8. Replace the access panel, external devices, and reconnect the power cord. 9. Turn on the computer and allow the operating system to start. BIOS Updates HP periodically releases system BIOS updates, which are available from the HP web site. These updates often contain fixes for known issues in the BIOS. To find out whether a PC needs a BIOS update, compare the current BIOS version number against the latest version available for download. To determine the current BIOS version, you should perform the following steps: 1. Click Start > Shut Down. 2. Select Restart, and then click OK. 3. When the first screen displays, press F10 to enter Setup. The BIOS revision number is listed on the main menu. 4. Write down the current BIOS version. 5. Exit Setup by pressing Esc, selecting Yes, and pressing Enter. HP Pro 4500, MT 640039-001 page 2
