    For safety, leave the 19v out of the equation. In the end, the mosfet is acting like a switch. Bridge the source & drain pins to force the 'switch to be closed'. Do not solder in a part at this location at all.
    My problem is completely solved..!!!
    The problem was that IC BIOS shows correctly with the programmer,
    But it was actually a problem.!!!
    that pin /CS (1) should not have any ohms with GND IN BOTH SIDE.
    In this CASE, pin 1 of the BIOS IC was damaged due to the MOSFET.​Also, I installed the MOSFET for IC BIOS' security ,like this and it worked great.

        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...
