Diagnosing problems with your computer can be difficult, especially if you do not have any visual cues to guide you. Fortunately, computer makers, like Hewlett Packard, make the job easier by using beep codes that computer owners can use to determine the source of the problem. By carefully listening to these beeps, computer owners can find the malfunctioning piece of hardware and resolve the issue.

  1. 1

    Look for the user guide that came with your computer. Having the user guide available will make it easier to track the meaning of the beep codes. Most HP user guides have a section covering the various beeping patterns and what each one means.

  2. 2

    Start your computer and carefully listen to the beeping. HP computers use both long and short beeps, so listen carefully to determine whether each beep is short or long.

  3. 3

    Shut down your computer and restart it. Listen again to the beep codes to be sure which pattern you are hearing. Write down the beep pattern and compare it to the beeping patterns listed in your HP user guide.

  4. 4

    Restart your computer again and look for any messages on the screen. Depending on the nature of your problem you might see visual clues, or the screen might remain blank.

  5. 5

    Check the status of the LED lights on the front of your HP computer as it is starting up and giving its beep codes. For instance, a red LED light often indicates a faulty memory module or an overheating processor.
