Lex's laptop was a laptop that belonged to Lex Luthor from seasons one to seven. Lex's laptop can often be found in the library of the Luthor Mansion. Lex usually closes the lid when anyone approaches the room so they can't see what he's doing. It also appears to be an "Apple" computer. The laptop then passes into the hands of Tess Mercer, since she inherited every thing that Lex had. However, it has been rendered useless as only Lex knew the password to access its files.
