Using System Diagnostics
System Diagnostics allows you to run diagnostic tests to determine if the computer hardware is
functioning properly. The following diagnostic tests are 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.
To start System Diagnostics:
