Troubleshooting a Mysterious Squeaking Noise from Your Laptop’s Heat Sink

If you’ve recently encountered a puzzling issue with your laptop, you’re certainly not alone. Many users find themselves perplexed by strange sounds emanating from their devices, and it can be particularly frustrating when the source is unclear.

The Issue at Hand

A rhythmic squeaking noise has arisen from the heat sink area of an HP model 15-dy machine, but intriguingly, this occurs exclusively when the charging cable is connected. The challenge intensifies when efforts to isolate the sound yield no conclusive results. After disassembling the laptop, detaching the fan and battery, the noise persisted, leading to further confusion.

Attempts to unplug the speakers and relocate them also yielded no resolution; the sound is definitely not coming from that direction. The sound resembles what one might expect from a hard drive or disc drive, but in this case, neither component is present in the laptop.

A Call for Insight

To assist in diagnosing this curious dilemma, I have shared a video capturing the sound quite effectively. If you have encountered a similar problem, or have any insights or suggestions for troubleshooting, your input would be incredibly valuable.

  1. Thank you for providing detailed information about the issue. Based on your description, it appears that the squeaking noise is linked to the heat sink area and is only present when the laptop is charging. This behavior could be caused by several factors, including electrical interference or components interacting differently under load.

    Here are some troubleshooting steps you might consider:

    • Check the Power Adapter and Charging Port: Inspect the adapter and cable for any damage or loose connections. Try using a different compatible charger if available to see if the issue persists.
    • Update BIOS and Drivers: Ensure that your laptop’s BIOS, chipset, and graphics drivers are up to date. Manufacturers often release updates that resolve hardware interaction issues.
    • Monitor System Voltages and Temperatures: Use tools like HWMonitor or MSI Afterburner to observe whether voltage fluctuations or temperature spikes occur when the noise starts.
    • Disable Hardware Components Temporarily: If possible, disable integrated components like the audio or other modules temporarily to see if the noise diminishes.
    • Consult Hardware Documentation or Support: Sometimes, specific models may have known issues with certain components. Checking HP support forums or contacting HP tech support could provide model-specific guidance.

    Since your disassembly did not resolve the issue, and the sound seems unrelated to the disconnected speakers
