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.

To start System Diagnostics:

1.Turn on or restart the computer. While the “Press the ESC key for Startup Menu” message is displayed in the lower-left corner of the screen, press esc. When the Startup Menu is displayed, press f2.

2.Click the diagnostic test you want to run, and then follow the on-screen instructions.

NOTE: If you need to stop a diagnostics test while it is running, press esc.
