Hello,

I have latitude e7270 with wrong motherboard. I bought new (used) one that works but my problem is, that there is new service tag. I tried to replace Bios chip and EC chip from wrong motherboard, also clean ME but service tag doesn't change to old one. Is there any possibility to change service tag on this model? I need it because software license is tied to serial number

please help.Thanks.
