Only fan and black screen after replacing battery
Recently I replaced the battery in my 2017 macbook pro 13” function key model.
After which when trying to boot all I get is power to fans and nothing else…no cap light on keyboard, nothing from the screen …just the fan.
I tried resetting SRAM and PRAM and this would cause the fans to stop/ power down but has not fixed the main issue of not being able to boot.
I got a replacement battery from Ifixit as they said it was possible I got a bad one and I even ordered a new power/flex cable that connects the battery to the logic board as the original one got a bit bent up and figured that could be an issue but still no booting.
I feel I was pretty thorough/ gentle with the repair so not sure what I would of/ could of messed up in the process but any suggestions would be greatly appreciated.
