I have a Toshiba Satellite A215-S4747 laptop computer which is about four years old now. It runs slow sometimes and I just recently read about upgrading the RAM. Other than being a bit slow, the computer is a workhorse and I've never had any major problems. From what I read, it is very easy to do. However, I've never done it before and I need a bit of advice. I've found this product which seems like it should work in my laptop, but I want to be sure. Right now I only have 1 GB RAM and my laptop supports four. This is a pretty good price. A single 2 GB chip is about $26. Can someone tell me if I'm reading everything right and these chips will actually work in my laptop?
