I have a faraday question. Answered

I have a laptop that is an hp pavilion dm4 and it has an aluminum covering on the lid and some of the key board, so I was wondering if I could protect my laptop from emp and stuff just by grounding the lid. If anyone could answer this I would appreciate it. Thanx

Put your lap top in an iron box.
Circuits are damaged because the electro-magnetic-pulse induces voltages in the fabric of an IC and overwhelms the transistors delicate
diode junctions burning them out resulting in uP and associated IC
death ( Faulty Function )..
The metal iron box absorbs both the electric and magnetic components o the em pulse before it can act on your lap top.

If it were a "proper" EMP - from an air burst nuclear weapon, I doubt if a tin box would stop it, because unless it was very thick, the shielding effectiveness wouldn't be enough.

Ha Ha Tin wouldn't do it.
I buy old style Iron filing cabinets for keeping my Magnets ( mostly ;-)

Not really. EMP is so fast that the connection to the ground acts like an open circuit.
