    Hi,
    i have the same laptop, so i thought i would be better to post here.
    Same situation. Stuck with an admin password.
    I got an eprom reader (EPZ2023+) but impossible to get the chip detected.
    I found those 2 chips, but to clamp doesn't seem to be in contact with the chip.

    I don't see where else i could attach the clamp. Has the chip the be desoldered ?

    Any help would be much appreciated.
