Il Mio Problema
The laptop was completely un responsive with just the changing light
La Mia Riparazione
I followed the battery replacement guide to get the battery out from there it was a case of removing the remaining connectors lifting the motherboard out, removing the heatsink and putting it all back together.
Il Mio Consiglio
The screws that hold the heatsink on are pretty stiff - i used a bit of PTFE spray.
