Used this guide and my MacBook is back to life! However I have noticed that the time it takes to charge the battery is very long. Seems like it would take 6 hours or more to completely charge.
Never mind. I was able to pop the second chip back out and get it seated properly.
I replaced my original 2x 2gb ram with 2x 4gb RAM following your instructions. However, upon boot up, it’s only showing 1 of the 2 4gb chips. Any tips on how to get both seated correctly?
