Chosen Solution

I have a 2013 13” MacBook Pro (A1502). I was using it normally with no distress for a long time. One day it refused to switch on in the morning (no damage of any sort). The MagSafe charger is stays stable at Green (and sometimes Amber). I have tried: Leaving it on charge for a long timeReset both SMC & NVRAMThe MagSafe light switches from Green to Amber and back to Green when doing the SMC ResetLong pressing the power buttonDisconnecting Battery, connecting MagSafe and long pressing the power button The fan does not switch on; the laptop looks like a brick at all times - the only sign of life is the MagSafe charger. Please help!! Edit: Corrected a typo: Its a 2013 model MBP not a 2015.

Lets do this short across these two pads briefly

Did the system startup? Did you see the fan move a little?
