Often it will be a broken via inside the PCB or a joint underneath a 480
pin BGA, in which case you need the x-ray machine.

I suspect it's either the chipset or the GPU (both soldered directly onto
the mainboard). Before spending $1000+ on a new laptop, I think I'll try
heating the pins with a regular soldering iron (25 Watts) in the hope that
the flaws, if any, will heal themselves. Is this a good idea?
