    HP 450 probook G4 bios chip replaced

    For lack of where else to ask this...

    i replaced the bios chip on my mothers' HP probook 450 G4.
    The laptop boots into win10 no problem & nothing appears amiss.
    However, it takes a while 15s for the HP logo to appear on bootup & i notice that the caps key LED blinks 5 times.
    i also noticed in the bios screen that the serial number & product ID are different (not 0xFFs or blank but actual values) to the values on the laptop case.
    My questions are:
    1. Will the fact that the serial# & product ID are not the original cause the slow post?
    2. How do i change them if they are the cause?
    I do have NbDmiFit-2.13 but but i cant unlock the ME because there's no point in changing FSMC.bin to SMC.bin as the UUID is not 0xFFs nor is the serial# blank or 0xFFs (and i'm not even sure if the Wndmifit64.exe is in that release is the right one for this laptop.)

    thanks in advance.

      Post your original as well as new l bios in bios section. The DMI info like serial ,model etc can be copied from older bios to new bios chip thru hex editor. Late display is due to dirty me region. Ask for clean me bios in the same section of this forum.

          ok..but where can i get the information that will:
          a) indicate where in the bios the information is stored (i dont have the original bios dump).
          b) get the program that will clean the ME region?

                      Common SPI bios chip programming Questions and Answers
                      ----------------------------------------------------------

                      Q: I have a bios request,i can`t post my backup as i can`t read from the chip.

                      A: If you can`t read from it how do you expect to write to it ?.

                      Q: Why is my bios chip unreadable ?.

                      A: The programmer is faulty or has a worn or broken zif socket.

                      The USB cable is frayed,connector pins worn or some other physical damage.

                      Not enough amperage or voltage to power the programmer properly.

                      Asus Chromebox CN62 - wrong chip put on BIOS reader
                      by BMCappelletti
                      Long story short:
                      - dad converted Asus Chromebox CN62 into Windows compatible, with mrchromebox BIOS, years and years ago
                      - gave the computer to his son a couple years later
                      - son now decided to revert it to Chrome OS, to sell it as original (re-writing BIOS with the backup one created by his dad)
                      - too lazy to remove the board from the case, thought a voltage regulator was the BIOS chip (you know... it has 8 legs)
                      (seems like the story was not that short)

                      He used alligator clips to read the chip. No luck reading it. Removed chip and placed on a SOC-8...

                      Lenovo laptop does not turn on, what does this number mean in a BIOS chip?

                      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...
