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.

Choosing recovery discs • To create recovery discs, your computer must have a DVD writer, and you must use only high quality blank DVD+R or DVD-R discs. NOTE: You cannot use CDs or DVD+RW, DVD-RW, DVD+RW DL, DVD-RW DL, DVD+R DL, or DVD-R DL discs to create recovery discs. • Use high-quality discs to create your set of recovery discs. It is normal for discs to be rejected if they are not defect-free. You will be prompted to insert a new blank disc to try again. • The number of discs in the recovery-disc set depends on computer model (typically 3-6 DVD discs). The Recovery Disc Creator program tells you the specific number of blank discs needed to make the set. NOTE: The process of creating recovery discs takes some time to verify that the information written on the disc is correct. You can quit the process at any time. The next time you run the program, it resumes where it left off. Creating recovery discs To create recovery discs: 1. Close all open programs. 2. Click the Start button, click All Programs, click Recovery Manager, and then click Recovery Disc Creation. If prompted, click Yes to allow the program to continue. 3. Follow the onscreen instructions. Label each disc as you make it (for example, Recovery 1, Recovery 2). Compaq 100eu AIO Illustrated Parts & Service Map 625297-002 page 3
