    lenovo flex 5 bios dump, anybody?

    hello all,

    i'm looking a bios dump for a lenovo flex 5 1470 type 81c9

    i found a dump online and paid $5 for it, but it doesn't boot on the machine either..
    symptoms:
    power on, but no display
    keyboard backlight flashes off, fans turn off
    fans turn back on and stay on
    only pwr button is illuminated

    i took the internet dump and cleaned the ME, but still no boot
    i cleaned the ME of the existing bios, but it's just too messed up i guess

    original firmware is CSME 11.7.0.3290
    internet dump is CSME 11.6.10.1196

    can anybody provide a good firmware?

          that is some serious brevity. are you referring to the manufacturer bios update executable?

              that's a great point.
              i downloaded the OEM bios update from:
              https://download.lenovo.com/consumer...s/4qcn45ww.exe
              but i couldn't convince any utility to disassemble it

              i would value the opportunity to learn from repairing this bios! i have UEIF tool as well as the intel CSME system tools.

              how can i attach the dump here?

                Below the message box ,click on "Go Advanced" . From there you can attach your dumps, as .zip or .rar .you might have read my post above before i edited it.I edited it because it looks like the bios.exe from lenovo only has a bios update,not the full bios, just wanted to avoid any confusion.

                  Re: lenovo flex 5 bios dump, anybody?

                  is there an activity threshold which i must exceed before attaching things, or am i just blind?
                  i only see Submit Reply, Reply, and Up buttons beneath the message box. beneath that is the footer bar w/ legal info.

                  assuming i can figure out an attachment, i'll post both dumps tonight.

                  thanks

                          Use this bios,but forget the ec ,its just here for others to use with a KBC programmer.

                            excellent news!
                            I have a booting laptop.
                            but as somebody (keenly) observed earlier, what do i do about the windows licensing now?

                            is there a way to acquire the windows licensing information from the corrupt dump and import into the new ROM?

                                ahh. i was in some "view mode" which didn't have the "go advanced" button.
                                attached is my original dump.

                                  I hope you understand now , why i asked to post your non working bios dump in the very beginning.

                                      this is a very circuitous lesson you're trying to teach. i wasn't asking for somebody to do the work for me, and for somebody as kind as SMDflea to teach me how to do this unforeseen task myself, posting my original dump still remains unnecessary.

                                      all in fact i needed was a working dump, which i received (many thanks!)

                                      here are photos of the key and DMI info from my corrupt dump. i'm going to just overwrite these chunks into the working dump...

                                      just posting them here in case i missed something or made an obvious mistake.

                                      cheers

                                        Re: lenovo flex 5 bios dump, anybody?

                                        in the future should i encounter this again, are these standard offsets for these data in PC bios? or is there something i should be searching for...

                                        i work primarily on apple EFI, which is structured nearly identically across all systems depending on model year.

                                        thanks again

                                          my laptop is lenovo flex 5 14ITL05

                                          recently my power supply for this laptop developed a fault.
                                          which caused a short in my usb c port -- verified with a new charger.

                                          rant: so, i went to the repair tech in my country, he asked for a huge repair cost when i decided to get it done someplace else this "great person" nicked my bios chip, asked me to be aware for repair scams lol.
                                          I was stupid and unable to find the flaw at the moment. Another repair tech told me that my bios chip was stolen and an 8mb bios chip is in place of that. he told me that a 32...

                                          Need BIOS Dump/ROM for Lenovo Thinkstation p500
                                          by AHmad_Salal
                                          Hello all,
                                          I have a Lenovo Thinkstation P500 that is stuck at post with no display, it happened after I changed the memory timings in bios. I can not clear CMOS using the jumper on the motherboard, also tried re-flashing bios suing a USB stick but it also doesn't work. The only solution that I can think of right now is re-flashing the bios chip using an external programmer but the problem is that I don't have the bios dump of p500 for flashing externally and I don't know the location of bios chip. If someone can provide the bios dump and bios chip location it would be really helpful....

                                          [REQUEST] 2MB BIOS Dump for Lenovo NM-E471 Rev 2.0 (Winbond 25Q16JWSIQ Chip)
                                          by hyperwood
                                          Hi everyone,

                                          I’m looking for a 2 MB BIOS dump for a Lenovo IdeaPad 5 16ARH7H / Legion 5 with mainboard NM-E471 Rev. 2.0.

                                          The BIOS chip is a Winbond W25Q16FW (1.8V, 2MB) and it's completely unresponsive / bricked. I tried recovery via USB but no success. Now I want to reflash it externally using a CH341A programmer.

                                          I already found 32MB dumps (e.g. from Vinafix and Badcaps), but they are too large for the chip – and the last 2MB in those files are just FF FF FF....

                                          āœ… What I need:
                                          • A working 2MB BIOS dump
                                          • Matching NM-E471 Rev. 2.0, e.g. JY575
                                          ...

                                          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:
                                          ...
