So I have a Acer ES1-P0SY-512 and bought it through Best Buy with 2 year warranty, I was having problems and took it in for getting fixed. The good news is there was actually a problem with my 8 GB of DDR3L Ram the bad news is they replaced it with 4 GB... This isn't allowed right? In case it helps i'm Canadian. I would love opinions on why they would do this and what they should do to fix it, Thanks for your time.
