Swapped CPU from Fujitsu to Dell - boot guard?

[estabilito]

Hello, i just swapped CPU(i5-8350u) from fujitsu lifebook e548 to Dell Latitude E7490 Board, all resistances are fine, laptop wants to boot but after 1 second draw of 0,3A its turning off, after pressing power on button same situation. I've cleaned ME region and same situation. Is it boot guard problem - and if it is, is it any chance to bypass this or this cpu just can't be used in Dell.

Still not aware of any trick to bypass bootguard. Btw, Was the source and target SOC same SKU?

If the e548 has no boot guard you can mod the E7490 bios ME firmware. Change boot guard to 0 and fill the OEM key with 00`s of the same length as the dell OEM key. It should be ok then, but you will have to make sure the bios doesn`t get updated. If you did it the other way around and put the dell CPU onto the e548 it wouldn`t work as boot guard is burned into the chip.
