    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...

    Lenovo Y40-80 bios
    by goldhawks
    Hi all, I have a Lenovo Y40-80 that I am trying to remove the Admin password for. There is a password screen that comes up immediately that I can input a user password for (Pic 3) and this will allow me access to Windows or the BIOS, but a majority of the options are grayed out in the BIOS (Pic 4).

    I have attached a picture of my overall chassis and a close up of the chip that I have read (using CH341A and AsProgrammer). I output two files from the chip and compared them (fc /b) and they were the same. I patched the first file (the file felt like it processed too quickly) and then...

    Asus K555U taking extra current
    by caspian
    Dear Members,
    This laptop used to work with a 19v 3.4A adapter.
    After 4 years of using it, now, the adapter's output voltage drops to 17v when windows loads up. Then the laptop suddenly turns off.
    Today, I have connected a 19.8v 4.5A adapter to this laptop. Then the adapter's output voltage dropped to 19.4v but the laptop worked fine.
    In addition, I noticed that the cpu power coils get warm to about 50'C but the mosfets are cool.
    All the voltage rails on the mainboard are fine without any reduction except for the 19v rail. All the ICs and coils on the mainboard are...

    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....

    Lenovo V340 17ML SVP removal method - ITE8586, I7-8565U
    by Stefan Steff
    Hi !
    I wish to know how to remove SVP from this model with I7-8565U CPU.
    Try already the MEC method, read EC-erase-wait5 min-write back but password remains.
    Obviously the Lenovo Autopatcher not working for 8th gen CPU.
    So how to do it?

    Thanks

    List of compatible motherboards

    [ATTACH=JSON]{"data-align":"none","data-size":"small","data-attachmentid":3281468}[/ATTACH]
    This is a list of compatible laptop motherboard information that I have been collecting for some time.
    And it's still ongoing.
    Every time I come across information that a board is compatible with another, I write it down.
    Anyone who wants to, can continue to expand the list.
    Packed in the rar, is an excel table that has additional information.​ [ATTACH]n3281467[/ATTACH]...
