USC and USC - LCE 23
Hardware Diagnostics
It is recommended that you run diagnostics as part of a regular maintenance
regimen to validate that the system and attached hardware are functioning
properly using the Hardware Diagnostics utility. Since the diagnostics utility
has a physical (as opposed to logical) view of attached hardware, this utility is
able to identify hardware problems that the operating system and other
online tools cannot. You can use the hardware diagnostics utility to validate
the memory, I/O devices, CPU, physical disks, and other peripherals.
See the following sections, for more information:
• "Performing Hardware Diagnostics" on page 36
• "Updating the Hardware Diagnostics Utility" on page 36
