      Try again with Password Generator.

      Use an External US Keyboard (QWERTY), use SHIFT Key for Uppercase letters, Hold left CTRL Key then Press ENTER Key twice.

            Re: Dell Latitude 7400 2 in 1 - Admin Locked

            I m gonna try now , but i think my programmer kill the bios memory . I read it with CH341A without making the 3.3 V modification and as far as i read the max voltage for this memory is 4.5v

            Now i get an orange light when i press the POWER button. I order a new memory . it should be in couple of days...is weird because i am still able to READ/WRITE on the programmer but when i solder it back on motherboard, orange light is coming ON when i press POWER button.

            I try to power the motherboard without the memory and it behaves the same...

            I ll wait the new memory and make sure i ll do the 3.3V modiication .

            Thanks

                  Man, Uou are Legend!

                  All working OK

                  No pass

                  Much appreciated!

                  So summed up, even if i read/write memory without the voltage hack on the programmer, everything is working but anyway i will do the hack just in case for further preparation.
