[Notebook] Sometimes there is a slight high-frequency noise coming from the laptop
When an electronic device like laptop, tablet, phone, etc. is working, sometimes you might hear a “beep” noise and it’s not coming from the speakers or the fans. This kind of high-pitched noise is called “Coil Whine”. It may occur in the design of today's high-power computer products, and is neither a hardware defect nor affecting the device.
What causes high-frequency noise (Coil Whine)?
When the system loading changed, the electrical current changes under the low performance of CPU. While the current flows through the electric components inside the laptop, it causes resonance and then high-frequency noise happens. This is the component characteristic, and it won’t affect the hardware.
How to prevent high-frequency noise (Coil Whine)?
The coil whine is easier to be heard in a quiet environment, or for the people who are more sensitive of higher frequency sound. ASUS will reduce the noise as much as possible, but this noise can’t be completely eliminated due to this sound is a physical phenomenon produced by normal using a device.
