Stuck in a boot loop
My computer is stuck in a boot loop. As soon as the battery is plugged in the fan turns on, computer chimes, fans stops, fan on, chime, and so on. The screen remains black throughout. I have replaced the logic board, RAM, and battery all without any improvement. Resetting the SMC and PRAM did not make any difference. If I unplug the ribbon cable from the keyboard, plugging the battery in does not start the fan or the chime, however with the cable unplugged I can’t turn on the computer at all. What do I do next?

What happened at the start of this? Did you have a liquid spill? Or drop, bang your system?

Does it work OK without battery? as @danj asked what happened?

The computer was turned off at night, I tried to turn it on the next day and this was the result. No drops or spills that I am aware of. It does not work with the battery disconnected either.

What color is the MagSafe chargers LED Amber or Green? If Ambor let it charger for a good 8 hours did it get to Green?

The charger light did change to green after several hours charging. Boot loop solved with new keyboard, but the screen does not come on at all now.
