    Probook 450 g3 i3 power on authentication

    Hi,

    Please help me delete/bypass power on authentication from this laptop.

    Have backed up bios, tried RCunlocker but power-on authentication is still there.

    Any other bios i've tried eg. the one from HP driver download page for that model results in power light coming on but blank screen, fan ramps up after about 10-15 seconds and no other response.

    I've attached the bios backup, and the copy unlocked by rcunlocker that is still power on password locked.

    Laptop product number is p4p38et#abu
    Motherboard is DA0X63MB6H1 rev: H

    thank you.

        Asus Probook P5440UF-XB74 power issue
        by GLISIT
        Hi all,

        TL;DR - this laptop is driving me nuts with the oddball power-related behaviors. Appreciate any insight you can provide!


        I'm experiencing a power issue on an Asus Probook P5440UF-XB74. Although I've worked with electronics and computers for decades, this is my first attempt at getting into motherboard-level component troubleshooting. Any help the community can provide is greatly appreciated!

        A few weeks ago I was using the laptop (on battery power) for a Zoom meeting. The battery was running very low (long meeting) but I wasn't worried about...

        Vizio e601i-A3 - Has Sound and Display, But No Backlight - Bad Power Supply Board or Bad LED Bulbs ?
        by Tynan Dill
        I was given this TV from my great uncle. He said it just wouldn't turn on one day out of nowhere, replaced the TV, and gave it to me to possibly fix and use for myself.

        Upon bringing it home and plugging it up, it showed a standby light.

        I powered it on and without a flashlight, the display showed the "V" but the lighting is very dim, but visible.

        The screen seems to blackout and stay black, but with a flashlight I can see the display.

        With my Playstation 4 connected via HDMI, and running a game I can hear sound.

        Assuming...
