Using System Diagnostics

System Diagnostics allows you to run diagnostic tests to determine if the computer hardware is
functioning properly. Depending on your computer, the following diagnostic tests may be available in
System Diagnostics:
●
Start-up test—This test analyzes the main computer components that are required to start the
computer.
●
Run-in test—This test repeats the start-up test and checks for intermittent problems that the
start-up test does not detect.
●
Hard disk test—This test analyzes the physical condition of the hard drive, and then checks all
data in every sector of the hard drive. If the test detects a damaged sector, it attempts to move
the data to a good sector.
●
Memory test—This test analyzes the physical condition of the memory modules. If it reports an
error, replace the memory modules immediately.
●
Battery test—This test analyzes the condition of the battery. If the battery fails the test, contact
HP Customer Support to report the issue and purchase a replacement battery.
You can also view system information and error logs in the System Diagnostics window.
