                  I currently have the same board with the bios password I don't have. And I am looking for a solution. I have seen that the board has 3 winbond chips and it really makes me doubt which one I have to replace or remove.

                      if the problem is only the Administrator password dump the 16Mb chip only and use RCUnlocker to edit the file and remove the password.

                          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.

                          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...

                          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...

                          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
