Hi, thanks for your reply. Unfortunately i havent found the dump i made before, i were sure its saved on my storage .. it is an X1Yoga Gen 5 with a I5-10310, attached you can find the specs and the S Nr. in the screenshot. meanwhile i flashed another bin from badcaps, one with a clean me. now i have a 3x blink of the power button LED after connecting the power supply, but after pushing the pw button still nothing happens. no cooler, no keyboard led - nothing. thanks for your help in advance !

thanks, but still nothing. only 3x blink power button LED.. no Fan, no lights, no display. i flashed in in-circuit, so better soldering out an flash in a adapter ? maybe the MEC1663 disturbes the flashing ? btw: its a W25Q256JVEQ ...

Yes! The bios i build is accurate with the model version so check the motherboard

Hi, so i soldered out an flash with xgecu. afer solderin in, same symptoms.. just 3x blinking.. i'm pretty sure, that the mec1663 ist blocking or is corrupted .. can i flash/programm an EC wit the xgeco T76 ? or do you have any suggestions for next check-steps / test workflow ?
