All of these signs point to a blistered battery which is pushing up from below pressing on the keyboard. As the battery has failed your Charger is now the only means for the system to get power which is why the system starts up on its own.

You’ll either need to find a local repair shop who can replace your battery or you can do it on your own but you do need to be careful! When I get a system like this I take it outside to remove the bottom plate and the battery as soon as the bottom plate is removed the battery has nothing to hold it back. This is when the battery can rupture and that is when the batteries can catch on fire! Make sure you have a safe work area outside and don’t have any flammable material on or around you.

Here’s an example of a failed battery!
