    Could someone please post a MATCHED bios and MEC1633l dump that works for the t450s (nm-a301)? The files posted do not work.

    Weird, when I flash the MEC dump you have posted with my RT809H the laptop will completely not turn on. There is no green light on the power and the fan does not spin up. I think this means that something is corrupt or incompatible with the MEC dump? I can flash an original one MEC dump or one from another site and it will partially turn on again.

    The previous owner wrote a corrupted BIOS to the motherboard and did not have a backup. The laptop has a miss-matched bios code and MEC code and will not boot due to that.

    Here is a MEC dump that I took with the RT809H that was on the laptop. This one does a brief green light but then turns off because it is miss matched with the BIOS on the laptop.

    I do not have the original BIOS for the machine. I bought the motherboard broken from a failed BIOS flash. As you know you have to have a matching MEC and BIOS for the machine to boot. So I need both.

    I am not sure if there is a language barrier or you are just not understanding what I need...
