    ASUS Vivobook 14 OLED M3401QA not posting
    by Luke11037
    Hello everyone,

    I have an ASUS Vivobook 14 OLED M3401QA which is not posting. Currently when plugged into power/turned on the power indicator will illuminate and the battery indicator will flash white roughly once every 3 seconds. Leading up to this it would sometimes turn on and then other times not turn on, furthermore it also showed a screen saying "new cpu installed, fTPM/PSP NV corrupted or fTPM/PSP NV structure changed" and then a screen telling me to recover the bios however it is no longer even posting at this stage.

    The diagnostics steps I have attempted...

    Macbook Pro A1706 820-00923 no power after replacing top cover and keyboard
    by johnbeton
    Hello,

    I have a A1706 with 820-00923-A board. The laptop came in with non-working keyboard. I bought a new top-cover with keyboard and transfered everything to the new topcover.
    Since then the macbook will not charge or power-up. Before replacing top cover, I started the macbook to test, and it worked fine apart from keyboard. Then shut it down and did replacement.
    This is what I measure so far:


    Resistance from F7000 to ground is 123 Ohm on pin 1 and 2

    PPBUS_G3H = 0,79v
    PPBUS_HS_CPU = 0,79v
    PPBUS_HS_OTH5V = 0,79v
    PPBUS_HS_OTH3V3...

    No display a1278 820-3115-B
    by dclass-pro
    Hi guys, I have this macbook a1278 which doesn't have any image on the display, but when I turn it on I hear the chime.
    I found the L9008 choke open and reset it.
    When I turn on the macbook I have about 3v on pins 3 and 4 of the display so everything is ok but I still don't have the image.
    On the backligt pin 21 and 22 I have 0v but the fuses are all ok.
    What can I check?
    I tried another display from a macbook a1278 but from the previous year and it still doesn't work.​

    Acer AN515-55-528T FH52M LA-J891P - Short ciruit after PQW1 MOSFET on +1.35VSDGPU rail.
    by joshAU
    Hi all.
    This notebook was showing no signs of life.

    I removed the FH52M LA-J891P mainboard and found that there was 19V at the DC jack.
    However there was zero volts on the two PRB2 and PRB46 resistors immediately after the two polarity protection MOSFETs (PQB11 & PQB12).

    If I remove the PQW1 MOSFET, the 19V rail starts working, and I can turn on the unit - at least I get the fans, and the power light comes on, when I simulate the power button being pressed. No display.

    I tried replacing the MOSFET with a new one, but again no voltage on the...

    Requests to Intel Flash Programming Tool for Linux Ubuntu x86_64
    by tsavpyn
    Dear all,
    I forgot my BIOS password of my Surface Pro 3, I searched for solutions for a long time and knew that by using FPT to dump my bios to bin file and using decryptor, I can get my BIOS password.
    Now I have a problem that I am unable to dump my BIOS into bin file.

    My Surface Pro 3 currently runs on Ubuntu 22.04, with Secure Boot enabled and Boot From SSD Only.

    I searched for FPT but there is no Linux version and none of them work.
    I hereby request a copy of Intel Flash Programming Tool for Linux x64.
    I would really appreciate it if anyone...
