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.
