                    Hi!
                    Hello, I have done the DMI process on the original BIOS but I still can't get it to give video. All the voltages and measurements are correct in the hardware, it even gives video via HDMI. The BIOS has problems. I am attaching the BIOS that originally came with the computer.

                    Equipment data:
                    Lenovo V14-IIL
                    Model Name: 82C4
                    S/N:PF2RTVJC
                    MTM: 82C400U2SP
                    MFG Date": 2021/07/29
                    Factory ID: YH
                    MO: PF9XB1729075

                    Please, if you can do something, I'll appreciate it. Thanks in advance.

                      This problem is happening on a few different lenovo models,and its caused by a bios update. Downgrading the bios to an older version should fix it.

                          I moved your post from the S145 thread as it was off-topic. A reply to your post in the S145 was made at the same time as i moved your post to this thread. I`ve merged that reply with this thread now https://www.badcaps.net/forum/troubl...85#post3460585 , if the downgrade doesn`t work try that bios

                            I have lowered the version and it still does not give video only through HDMI output, I have tried with the bios that you sent me and it still has the same problem, I have measured the entire video part from the connector all the way to the GPU part and everything is perfect, the fan works normally, the kbc has all its measurements correct.

                              Its not a problem with the bios then so must be hardware.

                            Can you send me a BIOS file that contains an older version? I would like to do some tests before reballing the CPU/GPU chip.
                            thank !

                              Check the fuses around the LCD connector (on the main board both sides).. There is a fuse for backlight and others on 3.3V and any of them may be gone.
                              I guess you have an LCD backlight issue...when the laptop starts up light the screen with a flashlight and if you see the Lenovo logo then sure the backlight is your problem

                                It drives me crazy because all the voltages exist, the fuses are perfect. The video line measurements using an oscilloscope are perfect, those waves are very healthy. I have replaced the BIOS chip with a new one and it still doesn't give video. Do you have any BIOS with an older version?
