Look for multiple tasks to accomplish when doing a major tear down. I had a bad speaker I was putting off and then the battery bloat hit so put in both speakers to make them the same age. Changing out parts on this machine is easy enough with patience and careful adherence to the guides.
I changed my SSD to a Samsung EVO 970 2tb. Much improved.
The connector slides into the socket so using the flat end of the Splunger under the cable and gently lifting draws the connector apart.
There is a battery cover with two T5 screws that must be removed before prying on the connector.
