The curse of the overheated graphic chips (or GPU Graphic Processing Unit) is similar to the plague of badcaps: a badly conceived and processed device found its way into a poorly designed system !
For the GPU curse, it is a perfect storm of
[1] a badly designed GPU (e.g. NVIDIA) chip with silicon hot spots, combined with the wrong bumping solder balls and defective packaging underfill. If the GPU chip overheats, the balls will crack and disconnect the GPU from the motherboard. Because in most laptop the GPU BIOS interrupt the boot BIOS during boot, the laptop will then not boot even though the laptop lights, CD and fan are working. In some cases, the laptop will nevertheless boot, but the display will be split, full of squares, or some component powered through the GPU e.g. WLAN will not work.
[2] very poorly thermal design of the laptop, causing GPU overheating and therefore ball cracking. For example, most of the laptop I gathered have a single heat-pipe from the GPU to the chipset to the CPU to the fan, instead of a dedicated heat-pipe for the GPU to the fan distinct from the heat-pipehooked to the CPU. Shame on you Dell & HP !
I just reviewed the stack of failed laptops; I hope that this list will help people that try to wonder why their laptops are not booting while all the lights/CD/fan are ON. The list is not exhaustive, but represents documented cases pf the overheated GPU curse.. All these failed laptops were quite expensive when first bought, and a significant loss for the small business. Some laptop families e.g. Dell XPS, Dell Latitude D630, HP DV2500/DV6000/V6000 have a 100% failure rate due to overheated Nvidia GPU.
When I have time, I will attempt to reflow all these GPUs, even though I know that the fix will only be temporary!
