    Hello everyone,
    Lenovo Thinkpad E14 gen2
    Board GE4B0/GE5B0 NM-D011 rev 1.0
    SN PF2HRFX9
    maybe someone can help me.
    When pressing the button, it turned on and immediately turned off
    Standby voltages of 3 and 5 volts appeared

    IT8227E-256 was not detected in the programmer (SUCCESSOR)
    After many attempts, I managed to dump it
    IT8227E-256 was replaced with a new one and flashed with the dumped one
    The laptop began to turn on, all standby voltages appeared, but there is no image, the power button blinks and turns off
    Tried different BIOS dumps from this site and vlab
    Flashed IT8227E-256 and 25R256JVEQ together and separately, the result changed But there was no image
    I am 100% sure that my problem is in the wrong BIOS
    Perhaps the dump 256 Kb is also faulty
    Maybe someone has a set of 256 Kb and 32768 KB
    Thanks in advance

      Thank you for your help. Yesterday I programmed your dump
      T8227E-256 and 25R256JVEQ the laptop turns on with the button and immediately turns off
      I tried probably all the options from this forum for the NM-D011 rev 1.0 board, but none helped the result either does not turn on or cyclic reboot or immediately turns off, the indicator blinks 3 times
      After numerous attempts to program with different versions of T8227E-256 and 25R256JVEQ I got a stable result, the laptop turns on, the processor heats up, the cooler turns on, the battery is charging, but there is no image
      I am posting a dump with which it works without an image
      Thank you

                    Hi ^^

                    I have a E14 Gen2 that boots, but then throws
                    Code:
                    0183: Bad CRC of Security Settings in EFI variable.
                    I cannot continue booting and entering the BIOS prompts for a supervisor password that probably doesn't exist. Entering the BIOS anyway by using maxpowers EC bypass method and emptying the supervisor password doesn't result in an update notification and exiting the BIOS yields
                    Code:
                    Failed to save storage: LenovoSecurityConfig. Status: Time out.
                    and
                    Code:
                    0187: EATA access error
                    after a reboot.
                    I can't tell if the BIOS itself is at fault or the EC and I sadly don't own an EC programmer. Also, the schematic and boardview reads like the EC firmware is in the BIOS firmware as well, is that correct?

                    S/N: PF-3FPE9T
                    Type: 20TA-00EWGE
                    Board: GE4B0/GE5B0 NM-D011 Rev 1.0
                    BIOS Chip: 25R256JVEN

                    I'd be very happy if someone could fix my BIOS dump or at least point me to the right direction.

                      Could you help me with this BIOS? The machine is beeping as soon as it turns on and doesn't give an image. I tried the BIOS published here, but some do the same thing. So I opted for the original BIOS to see if you could help me.
