To erase the RTC RAM: 1. Turn off the computer and any external devices, and disconnect power. 2. Remove the access panel. 3. Remove the RTC battery. 4. Locate the CMOS jumper header on the motherboard. It is labeled CLR_CMOS. 5. 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. 6. Replace the jumper on pins 1-2. 7. Reinstall the battery. 8. Replace the access panel, external devices, and reconnect the power cord. 9. Turn on the computer. 10.Hold down the F1 key during boot and enter BIOS setup to re-enter data. Hewlett-Packard Vision Diagnostics The Hewlett-Packard Vision Diagnostics utility allows you to view information about the hardware configuration of the computer and perform hardware diagnostic tests on the subsystems of the computer. The utility simplifies the process of effectively identifying, diagnosing, and isolating hardware issues. Use HP Vision Diagnostics to determine if all the devices installed on the computer are recognized by the system and functioning properly. Running tests is optional but recommended after installing or connecting a new device. To access HP Vision Diagnostics, you must create a Recovery Disc Set then boot to the CD containing the utility. It can also be downloaded from http://www.hp.com and either burned to CD or installed to a USB flash drive. 1. In Windows Explorer, go to C:\SWSetup\ISOs and burn the file Vision Diagnostics.ISO to a CD or copy it to a USB flash drive. 2. While the computer is on, insert the CD in the optical drive or USB flash drive in a USB port. 3. Shut down the operating system and turn off the computer. 4. Turn on the computer. The system will boot into HP Vision Diagnostics. NOTE: If the system does not boot to the CD in the optical drive or to the USB flash drive, you may need to change the boot order in the Computer Setup (F10) utility. 5. At the boot menu, select either the HP Vision Diagnostics utility to test the various hardware components in the computer or the HP Memory Test utility to test memory only. NOTE: The HP Memory Test is a comprehensive memory diagnostic utility that is run as a stand-alone application, outside of HP Vision Diagnostics. 6. If running HP Vision Diagnostics, select the appropriate language and click Continue. 7. In the End User License Agreement page, select Agree if you agree with the terms. The HP Vision Diagnostics utility launches with the Survey tab displayed. Using the Setup Utility The BIOS Setup Utility is accessed by pressing the F10 button during startup. The BIOS Setup Utility allows you to: • Change factory default settings • Set the system date and time • Set, view, change, or verify the system configuration, including settings for graphics, audio, storage, communications, and input devices • View processor and memory settings • Modify the boot order of bootable devices, such as hard drives, diskette drives, optical drives, or USB media • Run tests on the hard drive • Establish a supervisor password that controls access to the Setup Utility HP 303B, MT 630763-001 page 2
