Replaced battery and now keyboard does not work

MacBook Pro 2015 dead keyboard after battery replacement

Keyboard on MacBook Pro early 2015 dead after battery replacement

Hi guys,

I’ve just replaced the battery in my MacBook Pro 2015 model.

I turned the machine on to discover that a few keys were not working.

I opened the machine again to inspect the cables and decided to reinsert them.

The machine is now not turning on.

Have I damaged a specific cable?

Any advice is appreciated!

Thanks!
