The light on the MagSafe connector was slightly visible and occasionally the computer would not charge. Replacing the connector inside the computer seems to have fixed the issue.
Not sure how long it took, but this was not the first time I was opening the Macbook, so it was been there, done that.
Very careful with Step 11, this is how I broke the ribbon connecting the keyboard on a previous repair job (something was stuck inside the optical drive).
And, really, you guys have superb guides.
