Only boots after long disconnection from any power source
Hi all.
I received this A1502 Mid 2014 with a weird behaviour. Once it boots, everything works perfectly. Once it's been shut down, it takes hours and disconnection from battery and charger in order to boot again. It behaves ok if it just restarts. The problem only occurs when the machine shuts down.
- Battery is ok
- Charger is ok
- Same behaviour with logic board removed from the chassis (only fan and power board remain attached). This means it's not the I/O board, not a faulty keyboard.
- I'm pretty sure the SMC chip has been reworked, to no avail
Any help is appreciated. Thanks.
