            Hi friends,
            after the tests that you sent me, it was unsuccessful because the files that you sent me do not allow the bios to start, but if I put the original chip back the bios works but is restricted.

            i want install Win10 on my computer but I can't, I have a security on my bios, after.
            Thanks for your reply

              1st boot, press F2, write service tag, disable Absolute, save, restart. 2nd boot press Alt+F to exit manufacturing mode.
              Good luck.

                Hi Lapfix,

                I programmed the bios chip with the file you sent me, I reassembled the complete computer, when I press the power button nothing happens and if I measure the input of the charging connector, the voltage is 5v instead of 20v, and if I put the original chip back, everything works as it did initially, of course I do the tests with another BIOS chip, and not with the original one of the computer.
                Thanks.
                Zifan.

                  tôi đã lập trình chip bios bằng tệp bạn gửi cho tôi, tôi đã lắp ráp lại toàn bộ máy tính, khi tôi nhấn nút nguồn thì không có gì xảy ra và nếu tôi đo đầu vào của đầu nối sạc thì điện áp là 5v thay vì 20v, và nếu tôi lắp lại chip gốc thì mọi thứ hoạt động như ban đầu, tất nhiên tôi thực hiện các thử nghiệm với một chip BIOS khác chứ không phải với chip gốc của máy tính.
                  Cảm ơn.
                  Zifan.
