occasional loud, high pitched, sudden beep sound

[charlotte98]

Hi,

I got this laptop as a replacement mid lastyear as my previous (exact same model) had faults in its arrow keys.

The model is 13-ac041TU

This laptop that I have been using have been making loud, very high pitched and sudden beep sound ever since I have started using it. Each outburst happens for less than a second. The sound seems to becoming from the upper mid to left regions of the keyboard and I assume is unrelated to audio since the sound have been made during instances where the speakers were set to mute. 

It does not happen periodically nor very frequently so I cant exactly pin point what it is that triggers it. However the most recent outburst occured before the fan went off loudly (not a concern). This beep sound has become concerning as at several occasions it has happened during lectures. 

I was wondering if I can be provided with any information relating to the possible cause of this issue.

Hi! @charlotte98, Welcome to HP forums.

I understand you hear occasional loud high pitched noise coming from your laptop.

Don't worry I'll try to help you out.

Did you make any software or hardware changes on your PC?

As you mentioned you hear occasional loud high pitched noise coming from your laptop.

Try updating the BIOS on your PC and check if it helps.

Link to update the BIOS.

Check if any key on your laptop is stuck. Open a notepad on your PC and check if any key is typing continuously on your PC.

Also, try uninstalling and reinstalling keyboard drivers on your PC.

1. 1. In Windows, search for and open Device Manager.

   2. Click View and select Show Hidden Devices.

      Figure : Show hidden devices

      

   3. Click the arrow next to Keyboards, right-click the keyboard device name, then select Uninstall to remove the device from Windows.

   4. Continue removing device names in the Keyboards category until all device names have been uninstalled.

2. Restart the notebook. Right-click Start (), select Shut down or sign out, then select Restart.

3. Wait for the computer to restart and open Windows.

Also, Please try the steps recommended below.

Go to Windows Device Manager > Sound, video and game controllers section.
In the list of audio device drivers, look for Realtek or IDT High-Definition Audio. This is the device driver for BeatsAudio (a little bit sneaky, wouldn’t you say?).
Right-click and select Disable. The downward arrow displays on this driver, indicating it is disabled. (NOTE: At this point, you won’t be able to play any music files.)
Right-click and select Update Driver Software.
Select Browse my computer for driver software.
Select Let me pick from a list of device drivers on my computer.
You should see a window that says Select the device driver you want to install for this hardware. NOTE: If you see a window that says something like This is the best driver for this device, exit the window and repeat steps 4, 5, and 6.
In the Model box, highlight High Definition Audio Device (this is the substitute audio device driver) and click Next.
At the Update Driver Warning window, click Yes. You should see a confirmation window with High Definition Audio Device displayed. Click Close.
In the list of audio device drivers in the Sound, video and game controllers section, you’ll notice that the High Definition Audio Device now displays instead of Realtek or IDT High-Definition Audio.
At the prompt to reboot, click Yes.

If the issue still persists try the steps recommended below.

background intelligent transfer service (BITS) transfers files (downloads or uploads) between a client and server and provides progress information related to the transfers. If the BITS service is turned off, windows update may have problems delivering files to your computer.

Start the BITS service click start, and then click run.

Type services.msc in the open box and then click ok.

Right-click background intelligent transfer service, and then click properties.

On the general tab in the startup type box, click Automatic, and then click apply.

In the service status section of the properties dialog box, verify that the BITS service is started. if it is not started, click start.

Click apply, and then click ok.

Restart the computer and try to reinstall KB982381

Also, uninstall the audio drivers from device manager and install the latest audio driver on your PC using HP support assistant.

If the issue still persists try running a system diagnostics on your PC and check if the hardware components on your PC are functioning correctly.
