    EliteBook 8470p Missing LVDS_VDD after SDA_Main ESD Removal

    Totally unrelated, found p3v3_lvds at 3.3v but missing p3v3_lvdsVdd. Pin 40 on Cn3000 is at 19v. No backlight and no Keyboard Light. Pin 32, 33 are missing Inv and Backlight Voltages. External Monitor doesn't work.

    Laptop boots now both on battery and Adapter. We removed a Shorted ESD Diode from SDA_main to make it high as it was stuck on low. Battery now is charging but the display does show anymore.

      Fixed anyways, replaced the ram. I had no Idea the other ram won't work. I was thinking the bridge didn't just gave the enable pin
