        really? that will be super.

        actually I downloaded the dump bios file from online. I downloaded three different dump files from three different websites. I attached them all. and all are supposed to be for the MB I have.... but all gave me the same results. around 15sec black screen then shuts off.

        your help is very appreciated ... thanks

        kindly find the attached files...

            Please note that the MB was not working when I got this laptop. And that is why I tried to flash the bios.

            This is the the dump file I got it from the laptop itself at the very first time.... hope it be OK. .

                  Re: bios chip problem after 100% programmed using CH341A!

                  Hi guys, got a SOLUTION!!!
                  Problems with ERASING and VERIFICATION are caused by a badly made VOLTAGE on the CH341A - Bios chips usually run 3.3V. And it's alright with CH341A BUT the DATA LANES are fed by 5V. That's the reason the why you can't erase your chip, because of incorrect communication between your chip and the CH341A chip.
                  I've spent the whole weekend on trying to flash my Bios Chip via this programmer device. There are some TUTORIALS on the Internet how to FIX the Voltage for 3.3V by SOLDERING.
                  I don't have things for soldering. So I started thinking how to decrease voltage from my usb port from 5V to about 3V by connecting many hardware or something to the 1 USB Port. I've connected 1 USB Hub on this hub 1 usb lamp and a PS4 gamepad. Make a usb cable's length as long as possible. To this hub I had plugged the other hub and into this hub my CH341A. And BAAAM!!! After trying erasing, there was written: CHIPS ARE BLANK!
                  You just have to try connecting different things and longering usb cables for overloading the usb port and trying erasing your chip. Erasing has to take several seconds ( not 0:00:00 ). I think I have some problems with as programmer, so then I did it via CH341A PROGRAMMER v1.18. You will also need installing 2 drivers right from their chinese website ( don't be scared, it's not HTTPS ). Trust me, those 2 files are 100% clean and ok:
                  1. CH341PAR.EXE - this is a CH341WDM.INF device driver ( 06/05/2021 )
                  http://www.wch.cn/downloads/CH341PAR_EXE.html

                  2. CH341SER.EXE - this is a CH341SER.INF device driver ( 01/18/2022 )
                  http://www.wch.cn/downloads/CH341SER_EXE.html

                  I have done it successfully on WIN 8.1 on an old laptop and then on WIN 10 on my pc without any problems as well.

                  Hope it will help somebody!

                  GL&HF guys!!

                      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

                      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...

                      Q: Why is my bios chip unreadable ?.

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

                      Elitebook 840 G5 Bios Chip Soldering Question
                      by Azurain
                      Hi everyone,

                      I have an HP Elitebook 840 G5 that I am trying to get working again. I've removed the front bios chip (the 32mb one) and have run it through HP unlocker already. I've uploaded and verified the new bin, but am now experiencing an issue that has led me to believe I've been soldering the chip back to the motherboard incorrectly.

                      Essentially, after re-soldering the chip back into its place and reassembling the laptop, the charging light immediately flashes orange and white and then shifts to a solid white. The capslock and numlock lights blink seven times...
