I have an old Sony VAIO S series laptop (Intel core i3/ 2GB RAM) and I need to upgrade the RAM as 2 GB is too little for windows 10. I have a couple of questions though:
1. I think i have only 1 RAM slot to work with the 2 GB is soldered.
2. Can I only add another 2 GB (matching the default 2 GB) or can I add in a 4 GB stick?
3. Can someone please help me choose an inexpensive RAM? I can install it myself.
