looking at the white outline on the board, it looks low.
hopefully one row low, and not someplace in the middle!

Re: A1181 coreduo => core2duo upgrade cpu

when you lift the cpu, see if any of the balls had bridged.

what coil is melted? am i blind lol

Think it's L7620

so i poped these coils next to cpu out and they test very low resistance 1.0. same as on my parts board. idk how to test these.

i couldnt tell which side it was on or how to tell. i hope u can clarify a tad bit for me.

thanks for the patience

You're not checking the coils...lol...Need to desolder & check which side/pin is shorted on mobo pad & then follow in schematic which rail/component is causing that...
