Hi All
I've been having trouble with macbook pro 2013, so I swapped the battery and it still refused to power up. I tested the voltage on the battery and charger which were both good. Then today I tried powering up again and with the macbook upside down and the lid open by about 50mm I pushed the power button and it has sprung into life! Intermittently as when I opened it fully it went off again.
I'm suspecting a bad connection somewhere, has anyone else had this fault? I will do some in depth searching later on.
