This is my thinking. Have the battery on order and will change ones it comes I have the G31 so a bit more of a hassle but seems doable without tearing anything out. Managed to get a picture of the module and seems like it has been a little moisture around the edges of the battery cover. Will have to investigate this a bit better when I have time but it I’m starting to get a little worried that there has been water creeping in from the shark fin which caused some strange things happening.
