My daughter has been using her 14'' HP laptop since 2019. During this time there were 3 problems with PC - RAM (DDR 4), Wi-Fi and noise.

1. 2019. RAM. Out of box there was 4 Gb RAM, installed 8Gb more.
2. 2021. Wi-Fi stopped working. Once Wi-Fi has disappeared. In the device manager I could not see any wireless network. To solve it, I opened the case of the laptop and reinstalled the Wi-Fi module.
3. 2025. Strange noise. Also the case was opened and the reason was found almost immediately. A sticker from the mainboard has come off and was under the fan. Not very easy to find, but the fan is probably the only thing in the laptop that can creak. I removed the sticker and also cleaned the fan from the dust at the same time.

It’s the first time, when I have heard the reason of the noise from fan because of a sticker from the mainboard.
