    I have an HP DV9700T laptop. Is there a tech that reads this forum?
    My (9 O L . ) buttons are dead on my laptop.
    I ordered a new one & installed it. I still have the same problen.
    A friend told me it may be a component (chip, diode, or resistor) on the MB that died.

    There must be a tech that knows what controls these keys.

    Any help, Please??

    Have you tried an external keyboard? This will test whether your problem is with the keyboard, keyboard connector, or keyboard controller. Let us know how you get on.

    I have been using an external keyboard. Is there a chip etc that processes the input from the keys?
    Posibly this chip is damaged.
    We need a true PC IBMer w/ Phd in computer science who has (designed, developed, physically built pc boards & KNOWS this specific information).
    Where are you ? ?
