Hi, i wanted to ask about this weird sound that has been here since i bought this laptop ( 8 months ) but lately it has increased adding an electric noise.
it is always there, from when i boot up the laptop until i turn it off. It sometimes switches to a simple scratchy noise.
The sound is not very loud.
I don't think it's a fan problem because i've already checked them and they are clean.
When i bought the laptop i asked about this and they told me it's normal, but since then tha noise has been becoming worse.

- HP Pavilion Power - 15-cb030nl
- Intel® Core™ i7-7700HQ (frequenza base 2,8 GHz, fino a 3,8 GHz con tecnologia Intel® Turbo Boost, 6 MB di cache, 4 core)
- 16 GB di SDRAM DDR4-2400 (2 x 8 GB)
- Intel® HM175 (chipset)
- NVIDIA® GeForce® GTX 1050 (4 GB di GDDR5 dedicata)
- SATA da 1 TB (7200 rpm) - 128 GB PCIe® NVMe™ M.2 SSD

Here's the sound i'm hearing:

Do you know what this could be?
Thanks :)
