    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.​

    Hp pavilion 14 - No display
    by Nagyesz
    Hi all,
    Model: HP Pavilion 14-ce3010nh 8BV97EA
    Board number: DAG7ALMB8C0 - G7AL REV C
    Issue: I have an HP Pavilion 14-ce3010nh 8BV97EA laptop. When plugged into the charger, it turns on, but there is no display, the fans do not run, and the processor gets slightly warm. Unfortunately, I haven't been able to figure out what the problem is. I've reflashed the BIOS twice without any success. No post. Already tried out with another ram stick with no luck

    I measured the voltage with the HP turned on in red, and I measured their resistance with the HP turned off in green....

    by steveoski
    Hey guys looking for the Bios for an Asus ROG G713PV-DS94
    Motherboard Number is g713p-mb-VGT 6050A3468901-MB-A01
    Serial Number is R3NRKD03613412E

    i am not sure if any additonal information is needed if so let me know and i can update this post. Things i have tried are to download the BIOS directly from Asus but that file is a .329 file and is 32MB as opposed to the 16MB file i need. Scoured high and low and cant find this darn BIOS anywhere! Much appreciated!!...

    Macbook Air M1 820-02016 no screen (LCD_PWR_EN=0v)
    by SSBDADC234
    Haptic feedback on the trackpad works, and the app configurator on other MacBooks recognizes this MacBook.(not DFU status) That is, the power is turned on normally. However, nothing is output on the screen. no backlight, no image.

    Both screen and screen cables are fine.
    The result of the logic board check is as follows.
    PP1V8_S2 = 1.8v
    PP3V3_S2 = 3.3v
    PP5V_S2 = 5v
    PP3V8_AON_VDDMAIN = 3.8v​
    PP5V_SW_LCD = 0v
    PP3V3_SW_LCD = 0v
    PPVOUT_LCDBKLT = 0v
    LCD_PWR_EN = 0v
    PMU_SYS_ALIVE = 1.8v

    There is no short circuit in...

    Bios Clevo NL51RU
    by monitron
    I am struggling with a Clevo NL51RU linux laptop that does not boot because of a corrupt main bios.
    I did not succeed to build a new bios. Maybe somebody has more experience with this laptop and can build a working bios for me or has a working dump.

    Clevo NL51RU
    ser: NKNL51RU0001D00318

    Many thanks!...
