Acer nitro V16 new laptop making electrical buzzing noise. Need help

Jan_AAA

Hi, I bought the laptop a few days ago. I've noticed that sometimes, at random moments, I hear a small electrical buzzing sound, as if I'm unplugging and plugging something in. I wonder if you could help me.

Hi Jan_AAA,

Likely Coil Whine — Here's What You Can Try

What you're describing sounds like coil whine, a high-frequency electrical buzzing that can occur in powerful laptops, especially under load or during power transitions. It's harmless but annoying.

🧠 What causes it?

• Coil whine comes from inductors vibrating at high frequencies.
• It’s often triggered by changes in power draw — like plugging/unplugging or switching performance modes.

🔌 AC Plug Polarity Trick In some cases, reversing the AC plug polarity can reduce or eliminate coil whine. However:

• This only works with 2-pin plugs.
• If your Nitro V16 uses a 3-pin grounded plug, you’d need a 3-to-2 pin adapter to test this — but use caution and only try this if you're familiar with safe grounding practices.

🛠️ Other Tips

• Try disabling CPU turbo boost or switching to battery mode to see if the noise changes.
• Some users report reduced coil whine when using a high-quality surge protector or line conditioner.

Let us know if the polarity trick helps — it’s a subtle fix but has worked for others.

An electrical buzzing or hissing noise from a new Acer Nitro V16 laptop, especially under load, is likely due to coil whine, a common phenomenon in high-performance laptops. This noise originates from the vibration of electrical components like chokes or capacitors within the power delivery system as they handle electrical currents, according to Super User. While it can be concerning, it's often not a sign of a malfunctioning component and might not require immediate action if it's not excessively loud or disruptive.

Here's a more detailed breakdown:
1. Coil Whine:
What it is:
Coil whine is the sound produced by the vibration of electrical components, particularly inductors (coils) and capacitors, when they are subjected to fluctuating electrical currents.
Why it happens:
When a laptop's processor or graphics card is under heavy load, the power delivery system needs to provide more electricity, causing these components to vibrate at audible frequencies.
Is it a problem?
In most cases, coil whine is not a sign of a hardware defect and is considered a normal characteristic of high-performance electronics. However, if the noise is very loud or accompanied by other issues like performance slowdowns, it's worth investigating further.

2. Other Potential Causes:
Fan Noise:
While you mentioned an electrical buzzing, it's still worth checking the cooling fans, especially if the noise is related to the laptop's temperature or activity. Dust buildup, a failing fan bearing, or a loose fan can all cause buzzing or whirring sounds.
Loose Components:
In rare cases, a loose screw or other component might be vibrating against another part, causing a buzzing or rattling sound.

3. What to Do: Monitor the noise:
Observe when the buzzing occurs. Does it happen when the laptop is idle, under heavy load, or only when specific applications are running? This can help pinpoint the source.
Check for dust:
If the noise is related to the fans, try gently cleaning the vents with compressed air (from a safe distance and without inserting the nozzle into the vent).
Update drivers: Make sure your graphics card and chipset drivers are up to date. Sometimes, driver updates can resolve coil whine issues.
