The curse of the overheated graphic chips

Products affected by GPU fail

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!

The curse of the overheated graphic chips

Sadly, I have seen quite a few of the  DV2000/DV6000/DV9000 series here on the forums go through this over the years. It was so wide spread that several gpu repair services sprang up around the country. Some did a minimal reflow while others offered a complete reball. Some even did modifications to case cooling which basically just involved drilling more holes in bottom of case.

Ironically I still have a dv2000 series-dv2810us- which withstood the test of time and went from Vista to Windows 7. Spent many hours using it daily-but usually always with laptop cooling pad underneath it. It is now semi-retired but still running.
