Hi. I bought ACER SWIFT 5 ( Middle of 2019 ) for my younger sister and she found that many bubble back side of the laptop ( refer attached picture )
I contacted with Acer service center where is located at KOREA ( I'm living at Republic of Korea ) and they said " it is hard to check inside the PCB or laptop condition , if you want we can just replace the hard case".
If it is just problem of the hard case then it is okay but , when I see other person's case it makes me scary that will spread more and unknown problem at Laptop function .
so , I would like to know what is the correct reason and what should I do if same situation occur even after replace the hard case ?
