    Elitebook 850 G5 BIOS bricked

    Hello,

    I have an EliteBook 850 G5. After a Windows update, including a BIOS update, the notebook turns on, but the screen remains black, and the fans spin at high speed—nothing else happens.

    I assume the BIOS update failed, so I searched for the BIOS chip.

    I found a Winbond chip located between the RAM and the hard drive, which has a size of 32 MB.

    However, the BIOS update available on HP's website is only 17 MB in size. I used the update version that was previously installed when the notebook was still working.

    Can the corrupted BIOS on the 32 MB chip be repaired using the BIOS update?

        Read the chip again, it's only 78.4KB after compression.

            The system was previously running, as far as I recall, with BIOS version Q78 Version 1.27. I have now downloaded the previous update to Version 27 from HP's homepage and extracted it. I have placed this into the attachment, and its size is 23 MB.

                ASRock B650M PRO RS - BIOS CHIP 25Q256JW BLOCKED BY STATUS REGISTERS
                by DynaxSC
                Hi

                I have a very strange issue with the BIOS SPI chip of an ASRock B650M PRO RS motherboard.
                The SPI chip is an Winbond 25Q256JWEQ model (1V8).
                The motherbaord doas not POST - it lits only CPU and DRAM EZ Debug Leds, and stays that way forever.
                The Flashback function of the motherbaord is also not working, despite all instructions followed correctly - I'm 100% sure of this.

                I have then desoldered the chip, backupped the contents, and tried to earease the chip in order to program stock image, but the chip is locked by status registers SREG2 (TB) and SREG6...

                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...

                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...
