    Re: Hp 450 G4 rev D

    @sebulia - THANK YOU!!!
    I tried with 6-7 different BIOS for the 450 G3 that I found on the google and each one failed. The clean BIOS you provided allowed me to boot up and flash to latest (after I setup featurebyte, etc.).

    My original issue and story:
    For many months my laptop was acting flakey and sometimes when I booted up it would sound 2 long beeps + 2 short beeps, with flashing CAPS/NUM-lock indicating BIOS corruption. I would pull power/battery and restart, after a few attempts, it would boot up all the way. For a few months this got me by until one day all it would do is continue beeping. I was unable to get the BIOS to load from backup via USB key using Windows+B or Windows+V, and a few other recommended combinations. I had downloaded the N78_0151 BIOS (only one available on HP Support at this time), and it wasn't loading.
    Before selling on eBay, I was going to attempt to desolder the winbond BIOS chip and put in a new one, but then I found the clip on programmer, CH341a. I did a backup of the 'corrupted' BIOS and tried 6-7 other supposed 450 3G BIOS, but none worked. None of them had the corrupt BIOS beep codes that my original BIOS had, but half of that allowed a power-on would only spin up the fan, no video. The other half would make the power port light blink orange and would not allow power-on. Even flashing the N78_0151 (latest HP BIOS), would not allow power-on; strangely, the HP BIOS contained several empty pages, all 'FF' from 0-5C000. I eventually put my original 'corrupted' BIOS back in and I reproduced the original beeping behavior, which told me the programmer was working properly.
    When I found this forum, after flashing the clean factory BIOS you provided, it booted right up and I was able to set featurebyte etc by doing a S/N lookup in HP partsfinder.
    It's worth mentioning that I did check on the HP_TOOLS partition on the disk and all folders under Hewlett-Packard/BIOS/* were empty. In retrospect, before attempting to buy a CH341a programmer, I should have mounted the drive on another PC and dropped the N78_0151.bin into those folders to see if the backup system would pick it up. (I suppose I could put my original corrupt BIOS back on and try that, but not worth the effort at this point).

    Thanks again! Also, do you know why the new N78_0151.bin file contains several pages of FF at the beginning? Since I have updated to this version and it works when done through the HP utility, I can probably check if it was written as-is to the chip, or if it had to be moved around. The backup in HP_TOOLD/Hewlett-Packard/BIOS/Current contains a ton of FF in it as does the previous N78_133.bin, which I think was saved when I updated (based on the clean factory BIOS?).

      Re: Hp 450 G4 rev D

      In addition to my earlier question as to why the latest HP BIOS N78_0151.bin doesn't work, is there a way to look through my old 'corrupted' BIOS to find what my original System Board CT Number is? I tried decoding some of the QR/scan codes on the labels on the board and I couldn't come up with a value for this.

                Hi,
                Sorry for late response on this thread.The CT number is allways written on the board along with a qr code and sometimes you also have a sticker with a board code.Post the pictures with all the qr codes and i can try to help you out,but the CT code will only help you in case you send the board for warranty.

                        It's not so important. If you want latest version, you can afterwards easily upgrade the bios version to the latest available at the HP drivers page (in this way, the ME firmware will be upgraded simultaneously with the BIOS version). Correct cleaning procedure is important, so any relevant (same chipset family/platform Type/SKU etc.) 11.x.x.xxxx version is OK, doesn't matter much.

                          system restart after logo hp when system boot from usb key (linux) or ssd (windows)

                            Yes, I had a hard time understanding what you meant.
                            So where is your original bios? Upload your original dump here.
                            If you don't have it, try this one:
                            P.S. Did you try to update the bios to the latest, if not try that first.

                                Thanks to Vasco356 and SMDFlea for the answers. I found a bug using the schematic and boardview.
                                The LAN card communicates with the processor via the PCI-E bus, 2 x 2 transmitting and receiving lines. CN6 pin 20 socket, PCIE_RXP5_LAN line, no resistance to ground. Pin 19 shows several dozen kiloohms. CPU reflow didn't help. Break in pcb connection or processor malfunction.
                                Regards for all.
