Laptops With Certain NVidia Chips Failing
Eukariote writes "An estimated 18 million laptops with NVidia G84 and G86 graphics chips sold in the past one and a half years are experiencing high failure rates. Various laptop models from multiple manufacturers (Apple, Dell, HP, Lenovo, and others) are affected. NVidia blames it on bad chip packaging causing thermal failure. BIOS updates that turn the laptop fan on more frequently or permanently have been released by Dell and HP. The cynical interpretation is that this is likely to only delay the problem until the warranty has expired."
Having to have my laptop fan all of the time to account for a bad chip is an unacceptable fix. It's loud, it takes more electricity to run, and it shortens the life of the fan, and possibly the whole computer as a result.
I don't respond to AC's.

All Nvidia G84 and G86s are bad
The short story is that all the G84 and G86 parts are bad. Period. No exceptions. All of them, mobile and desktop, use the exact same ASIC, so expect them to go south in inordinate numbers as well. There are caveats however, and we will detail those in a bit.
Both of these ASICs have a rather terminal problem with unnamed substrate or bumping material, and it is heat related. If you ask Nvidia officially, you will get no reason why this happened, and no list of parts affected, we tried. Unofficially, they will blame everyone under the sun, and trash their suppliers in very colourful language.
When the process engineers pinged by the INQ picked themselves off the floor from laughing, they politely said that there is about zero chance that NV would change the assembly process or material set for a batch, much less an EOL part.
For dessert, there's this article to finish :)
As detailed in this thread, the GF8400 has serious performance problems under Vista Aero when running recent driver versions. I wonder if this is related? - i.e. Recent driver updates have down-clocked the GPU leading to bad performance. Dell have however recently acknowledge the problem and is working on a fix.
Here are the Dell models which have BIOS updates, from TFA:
Inspiron 1420
Latitude D630
Latitude D630c
Dell Precision M2300
Vostro Notebook 1310
Vostro Notebook 1400
Vostro Notebook 1510
Vostro Notebook 1710
XPS M1330
XPS M1530
A link? Shit I own one. Dell XPS m1330; I've had the motherboard replaced twice already for video failure, and I got the thing in September of 07. Yes, that's right, replaced twice in less than a year.
The flaw is every bit as bad as everyone makes it out to be.
waiting to form.
Charlie gets it right. Let's see, 18 million notebook machines. Freight each way, plus cost of labor to fix them and the materials needed. Less than $10 a machine! Great, that math stuff. Yup, a $150-200 million charge oughta do it at around $10 a machine!
Hello? This is the SEC? Hey, I have a question about an 8K I saw for NVidia. It goes like this.....

The article about trolling is the next one down. Easy mistake to make.

But it is Nvidia's fault because they signed off on these cooling units.
That is like saying it isn't your car maker's fault if they put breaks in your car designed for a lawnmower and instead it is obviously the people who are making these lawnmower breaks fault for not making sure they can break a much heavier car...
From what I'm reading the issue isn't with fans not performing as expected. The issue is that at the performance rate Nvidia had them at they simply didn't do the job needed and resulting in the GPU overheating and destroying its self.
It is entirely, 100% Nvidia's fault. If you put in substandard parts you get a substandard result.
I heard that Steve Jobs can smell a faulty substrate, even if it isnt going to fail for years, and that he personally sniffs every chip that goes into the production line to protect us Apple fans!

Agreed. Most reference coolers (and even a lot of 3rd party ones) aren't worth the cheap plastic used to make them. When I pulled the ref cooler off my 8800GT last year I was shocked to find that the fan didn't even sit completely atop the core, and that there was a LOT of excess thermal paste and stupidly thick thermal pads. It's little suprise the card was heatsoaking to 90C after a few hours of Bioshock and crashing itself! I can only cringe in horror when I imagine something like that stuffed into a freaking laptop. Fortunatly I had already planned on replacing the stock cooler (just a big heatpipe/heatsink with a 120mm fan ziptied to it) and lo and behold my card now has trouble hitting low 40's even after hours of flogging.
\ Long story short, all manufacturers should be held accountable for the idiotic shortcuts they take when it comes to cooling their electronics. Its kind of an important aspect of electronics, no? Why not spend a buck or two more on something that actually does the job? Till then the first thing I do with any graphics card (or CPU for that matter) is still going to be to chuck the stock cooler into my parts bin, and then look for something bigger or better.
Well, unless your replaced logic board fails again, I don't think Apple would take it back for replacement, since it basically works. Unfortunately, the affected GPUs are basically the entire nVidia 8x00 line (except for desktop 8300, and all the 8800's). Very few laptops actually use the 8800M GPU (think gaming laptops), so any other replacement, even a new laptop with an nVidia chipset will likely have the problematic GPU. The other alternative is to find a laptop with an AMD/ATi or Intel GPU.
Why is it all Nvidia's fault, seems to me it should be a shared responsibilty.
I work for a company big into mobile IC design (like NVIDIA). And I can say that it is very likely NVIDIA's fault because they (as do we), as the design company, specify every last detail of process, circuit, and package, when it comes to IC fabrication. Additionally, the company which produced these chips--TSMC--is the oldest, largest, and possibly most reliable dedicated fab company in existence. If there is a heat dissipation problem, it almost certainly stems from engineering oversight or management's corner-cutting on NVIDIA's part.

Unfortunately people think there's a difference with a macbook logic board (intel *coughs*) and an intel motherboard. Though a fan of OS X, Apple needs to give up on putting their apple logo stickers over the original 3rd party vendors hardware. It's a fucking PC/laptop with EFI.
