RE: Alienware 18 Charger Randomly Disconnects during gameplay
You're right, the battery needs to be removed as well for this procedure. I'm sorry I didn't mention that. First you need to remove the bottom cover. To do this, remove the 3 screws located above the vents, they are securing the front bottom door in place (you do not need to remove the other 2 screws above).
After you remove the bottom cover, you will see the battery on the top middle section of the system. There is black cable coming off the battery connected to the board, remove it from the board by pulling it gently straight up. Then proceed to remove the two screws securing the battery in place and you should be able to remove the battery after this. Try doing the power drain and let us know how it goes.
