    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)

              Thinkpad t480s, completely dead after BIOS flash using CH341A programmer
              by what_1282105
              Following this guide (https://www.reddit.com/r/thinkpad/co...g_and_flashing) i re-flashed my t480s BIOS using an external (CH341A) programmer. The flash didnt work, so i reverted back to my BIOS backup successfully. The BIOS in the chip and the BIOS backup file are identical according to windows' file compare. The revert, however, didnt work: the only thing the computer does is flash the power button 3 times when AC power is connected. I've tried unplugging the CMOS battery, holding the reset button and holding down the power button- no signs of life....

              Help Disabling Flash Protection Range Registers on Lenovo P360 Tiny BIOS
              by abhorsen
              Hey guys,

              Hope you all are doing well. I come here from Win-Raid because I am having issues disabling Flash Protection Range Registers so I can flash my BIOS from within Windows using Intel's IFW tool/using flashrom within Linux, however I cannot due to the above mentioned error.

              Here is my thread on Win-Raid detailing the whole process I went through: https://winraid.level1techs.com/t/re...h-gen/95478/27

              Essentially I managed to boot into Windows while shorting PINs 1+5 of my audio chip to disable the HAP bit...

              Is it okay to flash stock bios onto the motherboard's BIOS?
              by AkaBukai
              Hi there,
              I have a 14" Lenovo Laptop (Flex 5 14ALC05) which has a boot issue.
              The little LED on the power button is flashing slowly and nothing happen.
              This unit do not have any BIOS button cell battery so I tried many times draining the power but it is still not powering on.

              So I decided to flash the BIOS using a cheap programmer.
              And I was successfully able to read the content (exactly 16MB file) which BTW is a WINBOND 74m12jwsiq (according to the package inscription - but detected as W25Q128FW in the software - IMSProg on Linux)

              I also...

              Panasonic CF-20G0247VM BIOS Bad Flash Help
              by James Jackson
              I usually try to figure these things out on my own but am asking for help now as I have been beating my head against a wall.

              Backstory, I initially ended up with a CF20 Mk2 with a locked BIOS. I used aptio to read the BIOS and made the adjustments to the .rom file and attempted to write it back with aptio before reading other users problems with that setup. Well it bricked the BIOS go figure. Computer no longer boots, black screen. I found a clean BIOS on this forum but now I am having ME issues. So I would rather hand over the aptio dump(pre BIOS brick) and a hardware reader dump(post...
