    Do coils really get hot?

    I was wondering if coils around processor really get very hot? I was checking a defective board and tried to power it up, I notice 3 coils are getting very hot while its ON.

    yes, some laptops have cooling pads for it, but replace processor to be sure

      Initially the laptop got an i5 processor but whenever I power the machine up it turns off after 3 seconds. I've got and i3 with same series so I tried it out. it takes a little longer before it turns off. I checked everything around the processor and none is shorted. Here is the schematic. On page 33, PL19 and PL18 is getting very hot.

      At first I suspected PU6 is shorted but its not. Does not get hot too. board does not turn off when I run it without processor. So there's something wrong with cpu supply.

        Just cook it! It's already broken.

          take Pu6 down and resolder it!
          if that is the Cpu`s supply
          Just cook it! It's already broken.
