                  Thank you so much. Launched the fifth time with your firmware. Please delete my BIOS dump, there is a working windows key in it.

                        QUESTION: How to use bios.zip to recover bad flash?

                        BIOS update corrupted due to power fail during update.
                        System will not start, and screen is on but blank.

                        Can I reflash using the image in this post?
                        If so, is there a link to the recovery process?

                        I've done bios recovery before (specific USB in specific port, even JTAG) but I can't find anything for these Lenovo models.

                        Serial P9008T9H

                            I have three identical machines. Two worked, one failed. I have no backup bios from the update process.

                            But even if I had a backup, and you supplied a 'corrected' bios, what process would I use to reflash the chip? And could I perform this process with a bios copy from an identical system?

                            I'm missing something about the recovery process, and any explanation of 'how' would be greatly appreciated.
