    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...

    Surface Pro 4 1724 Core i5 8Gb, 256Gb, SNID: 048876262353
    by Daniel Muñoz
    Hello, I have a Surface Pro 4 1724 Core i5 8Gb, 256Gb, SNID: 048876262353.

    It turns on but remains on a black screen, with the logo and a red stripe with a padlock at the top.

    It doesn't get past this screen and I can't enter UEFI either.

    I have tried several "bin" files from the forum and they work, the OS loads but the touch does not work.

    Here is my original dump file.

    Please Help Me​...

    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.​
