    Retting BIOS Chip by a short

    Hi,

    I am currently trying to remove the BIOS Password. I have a W25Q128JV chip which stores my BIOS on.

    I have checked the manual online and it says that pin 7 is a /HOLD or /RESET.

    If I shorted pin 7 out by adding it to a ground would it remove the BIOS Password?

    4.6 Reset (/RESET)
    A dedicated hardware /RESET pin is available on SOIC-16 and TFBGA packages. When it's driven low for
    a minimum period of ~1µS, this device will terminate any external or internal operations and return to its
    power-on state

    4.4 HOLD (/HOLD)
    The /HOLD pin allows the device to be paused while it is actively selected. When /HOLD is brought low,
    while /CS is low, the DO pin will be at high impedance and signals on the DI and CLK pins will be ignored
    (don't care). When /HOLD is brought high, device operation can resume. The /HOLD function can be
    useful when multiple devices are sharing the same SPI signals. The /HOLD pin is active low. When the
    QE bit of Status Register-2 is set for Quad I/O, the /HOLD pin function is not available since this pin is
    used for IO3. See Figure 1a-c for the pin configuration of Quad I/O operation.

    This doesnt work on newer mb's. So better take out the chip from mb and read it with a spi bios prorammer. This saved bios dump you can post in "Bios Section" for help in removing password.

      Lenovo laptop does not turn on, what does this number mean in a BIOS chip?
      by thxd43
      Hello, first of all, excuse me, I am using the translator, English is not my native language.

      I have a Lenovo ideapad 330S - 14IKB laptop.



      The tablet did not recognize me when I connected it, so I checked the device manager and I realized that there were many with the exclamation mark, so one by one I began to update their drivers until the sign disappeared of admiration, I even updated the BIOS, and the laptop rebooted normally and worked, so far so good, but the tablet still did not recognize me, I read on the internet that it could be due to a...

      M715q Desktop (ThinkCentre) - Type 10M3 - Request bios chip location and useable bios for use with CH341A Programmer.
      by hotcrossedbuns999
      My pc updated bios through Windows Update and I was greeted with BLACK SCREEN WITH CPU FAN MAX SPEED. I don't think there is even a screen signal, because it triggers my monitor for a couple seconds and then the monitor turns off. I tried the other outputs as well.
      1. I tried clearing bios, resetting bios, removed the CMOS battery, removed m.2 ssd, wifi, and ram. Still black screen with CPU fan blasting.
      2. I tried using the Lenovo BIOS CD and BIOS USB, but neither worked. At least I couldn't get anything to work.
      3. I could only locate two chips that look like bios chips. Could someone verify this

      Acer e15-e5-576g-5762 bricked. Bios chip won't interface in AsProgrammer.
      by inck243
      Thanks for any help. The board version is DAZAARMB6E0 REV: E. The bios chip is winbond 25Q64JVSIQ1736. W25Q64JV is not available in AsProgrammer -- only BV CV FV or FW_1.8c. The chip won't interface with asProgrammer and a CH341A. When I have this chip on the board, the laptop will not post but when I plug it in to power, the blue LED lights up, also the orange when the battery is connected. When I push the power on button, keyboard backlight turns on and the fan starts briefely then turns off. But I can't do anything to program this bios chip so I bought another one.

      The BIOS...
