Hi all. I upgraded the RAM in my MacBook Pro (13 inch, early-2011) this morning. I was wanting to go from the stock 4GB to 8GB. I purchased the RAM online from Crucial, one of the most reputable brands around. However, after I had popped the new RAM in and tried to boot it, nothing. There is no life in this thing. The battery indicator on the side won't even light up. I wouldn't consider myself an expert in computer upgrades but I have done this before on other MacBooks so I knew what I was doing. I don't know if I've maybe nudged a cable by accident? I have tried everything listed on Apple's website to try and receive it with no luck. Have you guys got any suggestions before I go and book a Genius Bar appointment?
