Use the HP Image Creation & Recovery CD-ROM provided with your PC (refer to page 26) • If you are connected to a network, the slowness of your PC may be caused by the network. • Your PC may be infected by a virus. Use an antivirus utility to erase any viruses. Or, update your PC's BIOS. You can download the BIOS and updating instructions from www.hp.com/go/vectrasupport. Uninstall the software to see whether this solves the problem. If the problem continues, contact the software manufacturer for help or information on known compatibility problems. Yes. USB is supported by both Windows 98 and Windows 2000. Restart the PC and press Esc during the Power-On-Self-Test (POST). The BIOS version will be displayed at the top of the screen. From HP's website: www.hp.com/go/vectrasupport Sometimes your PC may appear to shutdown successfully when it has not. In these cases the operating system thinks that Windows has been shutdown incorrectly and runs Scandisk. A solution for this problem can be found at: support.microsoft.com/support/kb/articles/Q 273/0/17.ASP This only applies to switches that internally connect both power lines of the PS/2 mouse and keyboard.To solve the problem, use one mouse for each PC connected to the console switch. The beeps are created by the HP e-Diagtools pre-boot diagnostics utility. For more information, see page 19. The LEDs on the front panel indicate the various states your PC is in. The On/Off LED indicates the power modes status of your PC. The three states are: green (PC is on), blinking green (PC is suspended) and off (PC is off). The Lock LED indicates whether your PC is locked or not. The two states are: orange (PC is locked) and off (PC is not locked). This is because Windows NT SP6a uses 99% of the CPU. This issue has been acknowledged in the Microsoft knowledge base (Ref Q266208 available on: support.microsoft.com/support/kb/articles/Q 266/2/08.ASP?LN=EN-US&SD=SO&FR=0) If the PC is unplugged and then plugged in again, both the serial number and PCID are lost (reset to zero). If, subsequently, a pre-boot failure occurs before the BIOS has been able to boot the PC (and refresh the serial number and PCID in the micro-controller), you will see a null serial number and PCID in the Virtual Call Assistant. The suggested workaround to this issue is to communicate the serial number and model information over the telephone. 24
