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 support to report the issue and purchase a replacement battery.

You can also view system information and error logs in the System Diagnostics window.
