Noise from laptop

[RN0]

Hello, I have recently bought this brand new laptop and although it's not the loudest sound, there has been a constant buzzing/static/ squeaking sound coming from the left side of the laptop whenever the laptop is on and this has been slightly infuriating and uncomfortable. The sound is present regardless of the charger but the sound does get moderately/mildly louder when it is plugged in and I'm not sure if it's from a fan or not and I couldn't find what the cause is or if this is normal. I have noticed that whenever I switch or open new tabs in chrome, the sound gets slightly louder. Could someone tell me what the possible cause of this and a solution? Thanks.

Hi @RN0,

Welcome to the HP Support Community!

Thanks for reaching out!

We're thrilled to have the opportunity to assist you and provide a solution.

I understand your brand-new HP 15.6-inch AI PC 15-fd2000 (B59A8AV) is making a constant buzzing or squeaking sound from the left side, which becomes slightly louder when the charger is plugged in and during activities like opening new tabs. Let’s go through a few steps to understand what’s happening and how to address it.

Identify the Type of Noise

If the sound is a soft electrical buzzing or squeak, it may be coil whine (a high-pitched sound from electrical components like the power regulation circuits).

If the sound resembles airflow or rattling, it could be from the cooling fan.

Check Fan Operation

Open HP Command Center or HP Support Assistant → check system temperature and fan speed.

Place your hand near the laptop’s vent on the left side to confirm if the sound coincides with airflow.

If the sound changes when the laptop heats up, it’s likely fan-related.

Test on Battery vs. Plugged In

Since you mentioned the sound increases when plugged in, this suggests coil whine from the power circuitry.

This is common in modern laptops (especially high-performance AI/Intel models) and usually harmless, but it can be noticeable in a quiet environment.

Update BIOS and Drivers

Visit the HP Drivers & Downloads Page.

Enter your laptop model (15-fd2000).

Download and install the latest BIOS update, chipset driver, and graphics driver.

Sometimes firmware updates reduce coil whine and improve fan profiles.

Change Power & Performance Settings

Go to Settings > System > Power & battery > Power mode → select Balanced or Power Saver (instead of Best Performance).

In HP Command Center, set thermal profile to Quiet mode to reduce fan noise.

Test in Safe Mode / BIOS

Restart and enter BIOS (F10 key at startup).

If the buzzing still exists inside BIOS (with no Windows running), it’s hardware-related.

If it only happens in Windows under load (like Chrome tabs), it may be related to power draw/coil whine.

External Check

Plug the laptop into a different wall outlet or use a different charger (if available) to see if the sound changes.

Electrical grounding can sometimes amplify coil whine.

I hope this helps.

Hey, thanks for the reply. I believe the noise is from coil whine and I have followed most of the steps that you have mentioned. Can't be 100% sure but I doubt that the noise is fan related. I have changed power and performance settings but it didn't seem to do anything. I have tried safe mode/BIOS and entered F10 at start up and the noise surprisingly disappeared. When I plugged the charger in at that state, the noise did come back but it disppeared soon after. And about the BIOS and drivers, I realise that they can help but I've heard that they make permanent changes and can even be harmful to the laptop and the BIOS's only say that they provide security enhancements so I just wanted to double check if downloading them is the right call.  Same with the drivers (chipset and graphics), theres a total of 13 which I can see and I was just wondering if all of them are necessary. Thank you.

Hi @RN0,

Thanks for the detailed follow-up, it’s really helpful in narrowing this down. From what you described, it does sound like coil whine (since the sound disappears in BIOS and reappears under power load when plugged in). Coil whine isn’t a sign of damage—it’s a harmless byproduct of how power components handle electricity, but I understand it can be distracting.

About BIOS & Driver Updates

I completely get your concern about updates. To clarify:

BIOS updates from HP’s official site are safe as long as they match your exact model (15-fd2000). They don’t harm the laptop if installed correctly.

These updates often include power management tweaks that reduce coil whine or fan noise.

Chipset and graphics drivers also optimize how power is distributed to your CPU/GPU, which can influence coil whine.

You don’t need to install all 13 drivers, just focus on:

BIOS Update (latest version).

Chipset Driver (Intel/AMD).

Graphics Driver (Intel Arc/iGPU or NVIDIA/AMD GPU, depending on your model).

Those three have the biggest impact on coil whine and performance stability. The rest (audio, touchpad, etc.) can be updated later if needed.

Additional Workarounds

Power Plan: Keep your system on Balanced or Power Saver to reduce load spikes.

Charger Test: If possible, try another HP-certified charger. Sometimes coil whine differs with adapters.

Environment: Using the laptop in slightly noisier environments (e.g., a fan running in the room) can mask the sound if it remains noticeable.

I hope this helps.
