Apple MacBook Pro “Core i7” 2.3 15" Late 2013 (DG) Specs Retina Late 2013 15" - ME294LL/A - MacBookPro11,3 - A1398 - 2745 I’m asking this because I had three abscessed teeth pulled yesterday, on pain medication and thinking is just not all that good today ;=() @danj I know I know the answer but it’s not coming to me. I replaced a slightly water damaged keyboard on this machine about a year and a half ago. It has run well for the customer ever since. Running 10.11.6. Was able to all updates. When machine is shut down it will do nothing: when trying to power up from power button. Just dead, no sounds no lights. Did an SMC reseat and it starts right up and runs perfectly. I can’t remember right now what this is. Hoping someone can jog my memory.

Fought with this one for three weeks. New battery. Everything worked it just wouldn’t start. Could not find anything. I replaced the keyboard today. It all works now. Just that one bad key.
