    Samsung NP900X4C-A01CA BIOS

    I am working on a Samsung Laptop NP900X4C-A01CA. The status right now is NO DISPLAY but the motherboard is drawing .75 milli amps (Amps fluctuates up & down a bit) & the CPU & the GPU even gets hot. VCORE voltages are all good & all all voltages seem to be good. Can anyone repair/fix this Original BIOS fo this laptop. Thanks in advance.

        "peste"., Not working... I think there might be another problem with the motheboard. Same status as the previous original BIOS, motherboard just stuck on .75 milli amps.

          A lot of the older samsung bios get corrupted NVRAM . Try merging the bios update. https://www.badcaps.net/forum/showthread.php?t=88206 .The platform ID is ABK if its the original bios.

          Extract the DMI from the EVSA store using UEFITool (extract as is, just this EVSA store,not all of them) or with a hex editor 70AC00 - 70ADFF

          Samsung bios extractor attached.

            Thanks Peste & SMDFlea.. really appreciate!!! Going to do it for the first time.. Let's see how far I can go with this. So you mean I have to Extract the DMI from the EVSA Store & drag it to the Samsung Extractor with the Original BIOS Bin Files???

              No,the downloaded bios update needs extracting with the attached tool, then that extracted file wants copying/merging over the orig bios

                Thanks SMDFlea., 1st time doing this, so confusing. As I understand, 1st the original Samsung BIOS have to be extracted with the attached tool. & then extracted file need to be written onto a new BIOS chip. My apologies, did not get it, once I do it then it will be easier & even for everyone in this world. Thanks & thank you.

                  The extracted file needs editing as it has a capsule header ,Select off-sets 0 - 1CF (length 1D0) ,delete.Then there`s more editing to do to make it the right size... its a 3MB update (bios region).

                  Try this bios .

                    Re: Samsung NP900X4C-A01CA BIOS

                    Thanks you so much SMDFlea., when I download this BIN file which you have send me, is it already edited as I see the properties of it, & it 8MB. So I believe you have send me the edit version file??? Right? or should I delete the off-sets 0 - 1CF (length 1D0) & then this will be the correct file to be programmed on the BIOS Chip? Thanks

                              Thank You SMFLea, I've tried to follow the post that helps with downloading the Bios but I only get a 404 error from the server.

                              Here's the dump file from this laptop
                              Bios version and Platform ID as follows P06AAC

                              Thank you in advance

                                    OMG Hardware1 it's working like a charm. Thank you so much. I was wondering if you could let me know what have you merged into the original Bios, or if you could point me out some tutorials.

                                    Thank you again

                                      Good to know, You're welcome.
                                      After getting the file as you did in Post #16. This file isn't a Full BIOS Image (It's just a BIOS Region), so I replaced it with the old one (You can use UEFITool or HxD) then I cleaned the ME Region.

                                          🛠️ MSI GP75 Leopard MS-17E71 – No Display, Deep BIOS/EC Troubleshooting
                                          by macabook
                                          Hello everyone,

                                          I’m currently working on a dead MSI GP75 Leopard (MS-17E71) motherboard (i7 CPU, NVIDIA GPU) with a no display/no backlight issue initially. After extensive investigation, I’m at a critical stage involving EC firmware, BIOS/ME region interaction, and possible deep corruption. I'm seeking advanced insight from anyone with experience in EC/BIOS sync issues or PCH-level behavior. Here’s a full breakdown:
                                          🧩 Initial Issue
                                          • Board powers on (fans spin, keyboard lights up and can be adjusted, caps lock led lights), but no display or backlight
                                          • External display (HDMI) shows
                                          ...

                                          I need a BIOS dump for the Samsung S49CG934SU monitor
                                          by Habble7
                                          The Samsung S49CG934SU monitor does not power on - no LED indicator activity and no response to power button. However, when 21V power is connected, it immediately draws 0.8A of current with no display output. The motherboard processor gets warm, and there is continuous reading activity from the W25Q128BV BIOS chip.

                                          Suspected Cause:
                                          I suspect the BIOS may have been corrupted during a power interruption while updating the firmware. The official website provides firmware updates, but they can only be installed via USB flash drive.

                                          Troubleshooting Attempts:
                                          ...

                                          Samsung Galaxy Tabpro S BIOS and Micom Version doesn't match
                                          by TJ65
                                          Hello everyone,
                                          i made out of two broken Samsung Galaxy Tabpro S one that works partially.
                                          The one Mainboard had a broken screen output but working hdmi (usb c adapter) output and the other didnt start at all.
                                          I switch the bios chips and now the tablet starts but very very slow and it takes some trys to get it starting.
                                          The problem is, that the micom Version doesn't match with the bios version, see picture.
                                          How can i update the Micom Version? The Samsung bios update wont work.
                                          With https://github.com/tavinus/SamsungBIOSTools i could extract the newest bios update...
