LAPTOP SIREN

[GOSDSF1]

HP SPECTRE x360 - Why did this happen? I experienced a high decimal siren sound from my laptop. When the lid was open it sounded and quit when lid was shut. The siren stopped when the lid was opened and a headset plugged in. The sound could not be heard from the headset. I left the battery drain, recharged to 100% and I could open the lid without the siren sounding. It was so loud that we could not determine where the sound was coming from. ie laptop, smoke detectors, smoke/co detectors The fireman were called in and they could not determine either. They checked all my smoke/co detectors, wiring and batteries. Finally I found what was causing it when I shut the laptop!!!!!!!!!

Hi @GOSDSF1 

Welcome to the HP support community.
 

I understand you're experiencing an issue with your HP device, It sounds like you had a highly unusual and concerning experience with your HP Spectre x360, and I’m glad you were able to identify the cause. While it's certainly alarming when something like this happens, here are some possible reasons and explanations for what you encountered:

1. High-Pitched Warning Sounds (Hardware or System Alerts)

• Overheating Warning: Some laptops have built-in mechanisms to alert users if the temperature is too high. These alarms may sound when the CPU, GPU, or internal components reach unsafe temperatures.
• Battery or Charging Issues: If the laptop’s battery was malfunctioning or had an issue with charging, it could have triggered an alert sound.
• Internal Hardware Malfunction: Sometimes, the laptop might emit high-pitched sounds due to issues with internal hardware components like the fans, motherboard, or speakers.

2. Power-Related Sounds

• Power Surge or Issue: If there was a fluctuation in power, especially while charging, it could have triggered the laptop’s internal speakers to emit a high-pitched sound. Some laptops do this to indicate that there is a power or charging issue.
• Battery Issues: A battery that isn’t properly calibrated or has a malfunctioning cell can also cause the laptop to alert you in this way. This could explain why the sound stopped after you drained and recharged the battery to 100%.

3. Feedback or Grounding Issues

• Headset Jack or Audio Feedback: If the laptop's audio system has an issue with grounding or interference, it might emit feedback when speakers are active but could be muted or redirected when a headset is plugged in.
• Speakers or Audio Drivers: There could be an issue with the laptop’s audio driver or speaker system causing an unwanted alarm to be emitted, which is resolved when you connect a headset.

4. BIOS or Firmware Alert programmed into the BIOS or UEFI. If there was a system-level issue or miscommunication (like battery or power issues), this could have been what triggered the siren.

5. False Alarm or System Glitch

 temporary glitch or bug in the system:

• System Error: The laptop may have triggered a false alarm due to a system error or bug. Draining the battery and recharging it could have reset the laptop, clearing any temporary issues that were causing the alert.

I hope this helps! Keep me posted.

Hi,

What to Do Moving Forward:

Check for Updates: Ensure that your system BIOS and drivers (especially audio and power management) are up-to-date. These updates often resolve hardware-related glitches or errors that might cause strange behavior like this.

• Go to the HP Support website or use HP Support Assistant to check for the latest updates for your HP Spectre x360.

Run Diagnostics: HP laptops usually come with diagnostic tools. You can run the built-in HP diagnostics to check for any hardware issues that might be causing the alarm.

• Restart the laptop and press ESC or F2 to enter the diagnostics menu and run a full system check.

Monitor Battery Health: If the issue was related to the battery, you may want to monitor the health of your battery going forward. Some software can help with battery diagnostics, and if the battery is the source of the problem, it may need to be replaced.

Check Audio Settings: Investigate any potential issues with the laptop’s audio system settings, drivers, or external peripherals (like speakers or headsets) that could be influencing this issue.

Contact HP Support: If the problem reoccurs, especially after performing the steps above, it would be a good idea to reach out to HP Support. They can check if there’s a known issue with your specific model, run advanced diagnostics, or help with hardware replacements if necessary.

It’s good that you’re safe now, and I hope the information helps! If you encounter the issue again or need more assistance, feel free to reach out!

I hope this helps! Keep me posted.

HI Raj2111 - I do appreciate your feedback. I want the audience to know this was a siren that was like smoke/co alarms going off. You know it was bad when I had to call 911 emergency. When I plugged the headset in, why would I not hear the siren? When I unplugged the headset, the siren was happening again.

Hi @GOSDSF1 

Thanks for the update.

I really appreciate your feedback and understanding. That siren sound must have been incredibly unsettling, especially when it sounded similar to smoke or CO alarms. It’s definitely concerning that the sound was so loud it prompted a 911 call—thankfully, the fire department was able to check everything for you.It’s such an unusual issue, and I’m glad you were able to pinpoint the source and resolve it!

I hope everything is working smoothly now, and thanks again for sharing your experience!

 I appreciate your efforts in performing the steps to fix it and If you need further assistance feel free to reach out to us.
