    in he same boat... Help

    Hi I have poured through many of the suggestions and or solutions to the dell authentification problem.. My laptop was aquired after being disgarded at the dump two of them actually. I have no use for them but it seemed like a challenge to try and bypass this authentification system. moreover i decided to give the laptops to my son and his grandfather as they can make good use of them. well I have tried to jump the cute little chip using the paperclip method but unfortunitely after about a hundred tries I have given up. I guess either using them as paperweights or asking all of you are my only remaining options... I really enjoyed the challege so far but Im thinking strongly about using a hammer to fix the problem... any assistance you may offer would be great.
    have tried latitude,exe
    shorting method
