      Need Bios Dump for lenovo Carbon x1 20A7

      Have a Lenovo X1 Carbon type 20A7 that initially on power connection will fan spin for a couple of seconds and then maintain S0 rails for about 1~2 minutes before shutting down.

      Only thing I found overall was that the CMOS/RTC battery was 0V, replacing that hasn't resulted in any change of behaviour.

      Keyboard backlight will turn on with the fan spin and also shuts odwn in a couple of seconds.

      Attached is an image of the mainboard details as well as the 16MB BIOS.

      Not sure if this is a known mainboard fault or a BIOS issue or... ?

                Re: Need Bios Dump for lenovo Carbon x1 20A7

                Hi, i need some help with my BIOS on LMQ-1 12298-2 48.4LY26
                I am getting no screen. Before my laptop start failing (i am 99% sure that is bios related) bios battery got discharged really fast, after replacement battery happened again and the it stopped turning on. i replaced bios chip for the new working one, and loaded with clean bios i found on the internet.
                it started working , got the screen back, but after first restart failed again.
                I am suspecting that there may by some kind of short circut on BIOS line or something that it get corrupted.
                Do you have any experience with that. also can you provide me clean bios for my model.

                              It seems like you have a hardware problem. If you want help start a new thread in the main laptop troubleshooting forum.

                                      I have made two dumps of this bios, with the bios chip removed from the board and the hashes match on both dumps, but I cannot find the DMI information in the dumps except for the Windows product key, so I think it is corrupted. I have downloaded two bios updates from the Lenovo support site, but they contain small .PAT file, and 4 subfolders containing .FL1 and .FL2 files, which I don't understand enough to figure out how to use to fix my dump.

                                      The problem with the laptop is that...

                                      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....

                                      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.

                                      Hello! I need help getting a modified BIOS for my system. Since I have an engineering processor, is it possible to add the microcode of this engineering processor to the latest BIOS for this laptop model? I think since the BIOS is old, that's why the Wi-Fi driver is not installed on Win10 and Win11, the sound is not adjusted (error code 10 in the device manager) and the screen brightness. The laptop also has BIOS chips W25Q512NW and W25Q128JV, how can...

                                      First of all, ive veen reading these forums for some time and its always veen very helpful, so i thank you all for this amazing comunity.

                                      I have a lmq-2 13268-1 motherboard from a lenovo x1 carbon 3rd gen. And the MX25l12873f (U49) bios pin 8 is not getting voltage.

                                      So far these are my diagnostics:

                                      When given 19v trough power adapter, consumption reads 0.003 amps for about 5 seconds then nothing.

                                      When power button pressed same result, and i get three green blinking lights from the pwr btn led. But foesnt turn on.
