Re: LENOVO 320 turns on lights present cpu not spinning
If the cap was shorted, coil will also shorted to gnd.Since you measured 0.04K resistance, so cap was simply not shorted. It may have shorted now 'coz you applied heat to remove it. These sort of caps has a tendency to go short when heated-so you should replace it. You are simply getting lost in trobleshooting it. When laptop is turned on, try to measure voltage on all coils and see which rail(s) is not rising and focus on that part.
