I currently have Aspire 3 A315-51-31RD laptop with 1TB HDD and want to upgrade with an M.2 or mSATA if able. I used to have another laptop and had upgrade with mSATA easily. There was apparent slot when I opened HDD cover, but after uncovering A315-51's HDD cover it doesn't seem to have any slot for M.2 or mSATA. I guess either it doesn't have any or I need to uncover another layer.
My questions are ;
1. Is there M.2 or mSATA slot in my laptop?
2. How can I put them to upgrade in my laptop?
