    Need Help ! T480s Not Turning On after Bios Flash

    I have a lenovo t480s , i took a backup of the bios using ch341a and sop8 clip. Then i used the patcher to patch the bios. It turned on after flashing the patched bios. Up until when it says power off the laptop.

    After i flashed the original bios and the laptop has not turned back on since, no sounds , no lights except the charging light when charger is connected

    Any suggestions would be greatly appreciated.

            Hello, I had the same problem and I solved it by changing the bios bin file, I tried the bin file that they sent you but it doesn't work, it does the same to me, I send you the files that I use for my equipment, I used 2 programmers annex so that if you have time to cales, I also use the CH341A with tweezers, I hope it can help you.

            Chip bios flash with Neo programmer
            Chip thunderbolt flash with CH341Programmer (if do you need)
