Hello. I replaced the keyboard on my Late 2013 Retina, the first two columns of keys had signs of water damage (QAZ WSX) I don’t recall spilling anything on there - at the very most a few drops of water might have splashed it at some point. Anyways it was working fine for a week after the keyboard was replaced - but not it won’t charge and when I plug it in the magsafe light doesn’t light up. I verified it’s not the charger - another mac is charging up with it just fine and I tried another charger just to be safe. Is there any way to tell whether this is a logic board failure or could it be the internal magsafe or something else?

Unfortunately….you have a bad battery in the laptop. I have never replaced one. Life of a battery will max out after 5 years. I have replaced batteries in powered wheelchair and scooters with same symptoms. Thanks for asking, Matt of Martins TV Repair.
