    ZAB/ZAB A,B/ZYJA BLOCK DIAGRAM Acer Aspire

    Hey there people
    While working on my Acer Aspire with the OS failing to load, I encountered a motherboard number of DA0ZHQMB6E 0 REV: E. I was getting nowhere fast or slow, for that matter.
    This is what I tried, but not in any order.
    Google
    YouTube
    BIOS
    Command Prompt (administrator privileges)
    >
    On Google AND YouTube, I was getting mixed messages, try this and try that, but when you cross reference the advice it is either the wrong model (even though you enter the correct search term) a YouTube case in point, with the search term "how to reset motherboard on HP Stream laptop "https://www.youtube.com/results?sear...+Stream+laptop" mistakenly this is NOT what I am seeking.
    Google on the other hand is good but I must be using the wrong search term "da0y07mb6E0 motherboard factory reset pads" https://www.google.com/search?q=da0y...t=gws-wiz-serp
    >
    The first hit on that is an ASUS, even though my search term states "da0y07mb6E0 motherboard factory reset pads"
    >
    BIOS just does not help me, plus there is no CMOS battery to unplug
    >
    Finally, Command Prompt, sorry I have forgotten where I got up to with this particular area.
    >
    I don't know how, but I stumbled across https://www.badcaps.net/and its various Forum areas, plus I found a thread " [SOLVED] I'm looking for DA0ZY2MB6E0 REV E repair guide or schematics (free) - Electronics Forum"
    >

    So I managed to download said repair guide, which actually turns out to be a "block diagram" No worries, I then undertook a search within the PDF using the search term "reset", and this is the result.
    >
    The document contains the following content related to reset:
    1. Reset Button:
      • Located at P6.
      • Mentioned in the "Reset Button" section.
    2. Reset Signals:
      • RESET_L is mentioned in the "APU_RST#" section.
      • PLTRST# is mentioned in the "ACPI/SD/AZ/GPIO/RTC/I2C/UART/MISC" section. ​
      • SYS_RESET_L/AGPIO1 is mentioned in the "ACPI/SD/AZ/GPIO/RTC/I2C/UART/MISC" section.
    3. Reset Circuits:
      • DRAM_RST is mentioned in the "MEMORY INTERFACE" section.
      • DRAM_RST_M is mentioned in the "MEMORY INTERFACE" section. ​
      • LPC_RST#_R is mentioned in the "ACPI/SD/AZ/GPIO/RTC/I2C/UART/MISC" section.
    4. Reset Components:
      • EC_RST_L_BUF is mentioned in the "EC (ITE8987E/BX)" section.
      • EC_ODD_EJ# is mentioned in the "SATA ODD (ODD)" section.
    5. Reset-related Pins:
      • RESET# is mentioned in the "DDR4 SODIMM 260 PIN" section.
      • RESET_C is mentioned in the "NGFF_M.2 SSD (NGF)" section.
    6. Reset-related Components:
      • EC_SPI_RST is mentioned in the "EC (ITE8987E/BX)" section.
      • LRESET/SPI_RST is mentioned in the "TPM (TPM)" section.

    These references indicate various reset functionalities and components across different sections of the document. ​
    ​>
    Correct me if I am wrong, but of the SIX instances I don't think they apply (maybe the wrong terminology), I may have used the wrong search term. Advice needed.
    >
    The reason I am fixated on the term "reset" or "factory reset" is that I sat back, had a cup of tea, and thought about it logically: if I can take the machine back to when it left the production line, I can start with a clean sheet.
    >
    There are many more clever people out there than I, and I am always willing to learn.
    >
    Finally, I have looked at the motherboard under the illuminated bench magnifier, and I can not see any terminologies referencing "clear", or "reset" or even acronyms of that. If you have one of these motherboards, please upload an image showing the specified pads. PLEASE
    >
    So, after reading all of the above, I seek guidance on how to get back to factory settings.
    Till later
    Tony

    BIOS password reset for HP ProOne 440 G9
    by ch.wa
    HI,

    I have a problem with the BIOS password for the HP ProOne 440 G9 (AIO). Once I want to enter the BIOS a password is requested (see screenshot) and I am a little unsure if it would be smart to try a wrong password three times (as some people mentioned online) to get a code - I don't want to block the whole system (not sure if that could happen?!). According to other sources a reset is (maybe) not even possible for this model.

    Any ideas if this may work? Hope someone could help.

    Thanks for your time!
    Chris

    RJ45 Block Diagram / Schematic

    RJ45 Block Diagram / Schematic

    RJ45 network connectors are most commonly found at either end of an Ethernet (wired internet) connection. At first glance, they appear similar to the familiar telephone plugs and jacks which connect landlines to walls or switchboards. However, RJ45 connectors are typically slightly larger.

    The term RJ45 connector is widely used today to describe both male RJ45 plugs and female RJ45 sockets. The plugs, sometimes called modular connectors, are usually found on the end of Ethernet cables. The sockets or jacks are generally embedded in the device...

    Embedded Controller issues, living an absolute H*LL with my ASUS Vivobook Pro 16X OLED
    by GardevoirForEver
    I've been dealing with so many complications for months, trying to find and then fix the root cause of the issue I really need help and I have to solve this on my own (Going to Asus headquarters isn't an option for me. First, because I'm very stubborn and want to insist that I can fix this sort-of-myself somehow, and second, the location is too far away for me anyway).

    Right now I'm desperate trying to put an end to this nightmare, but OK, I'll do my best to be somewhat brief in explaining and relating the entire situation and context.

    Sony OLED XR-77A80J - 5 Flashes But Turn On After Hard Reset
    by odie34
    I am a hobbyist (not a professional) so please be gentle...

    I recently received an XR-77A80J that wouldn't turn on. (Repeating 5 flashes when plugged in.)

    I did a hard reset by holding the power button for about 30 seconds until the set powered down. I then tried to turn it on and it powered up, bringing me to the setup screen. There's not a lot of detail on the setup screen but the picture didn't have any distortions, so at least a cursory examination suggests no physical damage to the screen. The set appeared to be working normally, but it shut down after about 15 seconds,...
