I am not sure why the hostility but I explained much of this in earlier post. I also know that class D fire extinguishers are the only one accepted. Halon fire extinguishers can react with the lithium making it worse.
Why should I "guess" how to deal with it? I have told you the limitations, problems and issues. I would specifically look toward containment in containers which starve the electronic devise of oxygen, contain the smoke, and keep the molt ant fireballs contained.
If you have FAA videos or data of water experiments on laptops I am sure everyone would love to see them. I never have seen them and I don't know of anyone who has.
