I am just wondering what can be a squeaky noise coming from inside the laptop while it's being used? I've actually heard this noise before even when computer was shut down. I sent my I have a Spin 5 SP515-51GN-83YY laptop for repair a month before my extended warranty expired for them to fix this and they did not repair anything at all. I just find it annoying.

    This sound is called coil whine. Small electrical choke coils on the mainboard that control battery charging and cpu/gpu load often will emit intermitte nt high pitched sounds when being supplying electical current to the battery and the cpu. Many people, me included, cannot hear these sounds because they are too high pitched. It is a natural electrical phenomenon which is normal and usually cannot be completely eliminated.

    so why didn't it make this noise the first year after I bought it? Only until the last year it started.

    I cant hear those to because I’m partially deaf in 1 ear

    Coil whine was probably still present but at lower less-noticeable levels in the first months after acquiring the machine.  You have since likely added and are running more-power intensive applications that increase consumption by battery, RAM, cpu, HDD/SSD and especially  gpu if you play more up-to-date games or use graphics intensive programs. You might be able to reduce coil whine levels a little bit by decreasing screen brightness and clicking on the tray battery icon and move slider to the left for better battery life  but a bit lower performance.

    HP laptop doesn't make this noise. Instead it makes a fan noise. But this acer laptop similar to the model I have never made this noise even though it was also Spin 5. I remember technical support on the phone saying it could be the hard drive, but they didn't fix anything when I sent it.

    Dust is the most common cause of laptop noises. Dust damages your system in various ways including obstructing your laptops fan, which causes it to make loud noises. ... To clean it; you need to open up your laptop using a screwdriver and use a blower to remove all dust particles.

    Solid State Drives produce this high pitch coil whine, because SSDs have transformers that increase the voltage for writing. Transformers are pairs of coils exchanging energy through a magnetic bridge, with denser windings regenerating higher voltages from the magnetic field induced by the coils from the lower voltage coil. HDDs don't produce this noise, instead having spindles producing sound similar to fans. It could just be that the HP laptop has an HDD.
