          Dear Blaze Tech and others

          I broke my W25Q256JV bios (phisically) from HP EliteBook 840 G5 6050a2945601-mb-a01
          May I ask for BIOS for serial number 5CG013DSCM ProdID 2FA66AV please?

          I tried adjust bios bymyself to change Serial Number with HEX but still I have issue CPU fan spins at maximum speed.

            hello everyone, mistakenly i have read the main bios instead EC chip. now my laptop is working but keyboard is not working properly i think because of the main bios corruption. can someone send me the original main bios file for W25Q256JVEQ chip? in this model EC chip is located under the motherboard which is 128MB chip. in 256MB does not include security things like bios passwords and all. bios password i removed successfully from the 128MB chip by searching active on hxd file but after that also keyboard is not working properly and when i use with bios password it worked very well.i tried to reprogram with the backup that i mistakenly read for 256MB but the issue still appears. maybe i have not read it properly. unfortunately here i can not upload the attachments it says i am not allowed to attach bin file extensions. S/N 5CG922701G PROD ID 2FA66AV. i connected external usb keyboard also but issue persisits. please help me with it. thanks

              post merged...next time look for a thread with the name and model, motherboard model of the laptop, and post there, if you can't find it, then make a new thread..

            post the contents of the bios chip even if it is corrupted..archive with winrar or 7zip and post..
            post full name and model, motherboard model,

                  What I should do to let it run? Will you be able to prepare package for me to let it work?
                  Is it requires to flash also second 16MB bios as well?

                  Thank you
