pentium dual core t7500 saying revision not supported on laptops

I have a t7500 dual core processor that has a scratch on the side , but I dont believe the scratch is the problem, but whenever i install it on a laptop (i have tried it on three different ones but the other processors work fine ) and boot it to bios (all different versions) it says microde processor microde update failure
