Over heating DV9000/Intel (with defective Nvidia 8600)

I have an Nvidia 8600 defective card, as many people do in their dv9000 series laptop. Updating the BIOS and the driver won't work. Buying a cooler, and cleaning it out won't work either. If your card is beyond an small fix (completely dead), you will need to have the motherboard completely reinstalled. After you get it installed you will need to add a thermal compound/shimmy to buffer the overheating from happening a 2nd time. There are videos all over youtube on how to do this.  If your laptop isn't totally dead yet, just over-heating, use the youtube trick + the cooler and clean it out with compressed air.

 

If you get a case manager to work with you on it, he/she can give you a discounted price for a new motherboard and labor - around 300 bucks. Understandably, HP can't service everyone, because the truth is, more and more people are coming forth with different chipsets complaining that they are defective as well from Nvidia. This is a Nvidia issue.

 

As consumers, I am appalled. I understand your frustrations at HP, but as I checked out the BBB site, I noticed that there are thousands upon thousands of complaints against HP. And a total of 39 for NVIDIA?? Come on people, let's complain to NVIDIA as well. They are the ones that need to give HP the money to fix your laptops. Although HP should be demanding it as well, let's help it along by nipping it in the bud. File a complaint against NVIDIA to get your refund of $300...

 

These are all the complaints logged against NVIDIA:

 

1Making a full refund, as the consumer requested
0Making a partial refund
11Agreeing to perform according to their contract
6Refusing to make an adjustment
2Refuse to adjust, relying on terms of agreement
16Unanswered
3Unassigned
39Total

Over heating DV9000/Intel (with defective Nvidia 8600)

Los Angeles (CA) – A tiny material issue in Nvidia’s GPUs has cost Nvidia $200 million so far: The problem boils down to the solder bump material, in Nvidia’s case high-lead that was used in all of the firm’s GPUs that were produced until late July , and we still do not know how serious the issue really is. According to our sources, Nvidia has switched to eutectic solder bumps in recent weeks and there is now a new, apparently independent research report, that claims that eutectic solder bumps, which are used for example by AMD’s ATI unit, may live much longer than high-lead versions. Of course, switching to eutectic isn’t the entire solution, as the material has a much lower melting point than high-lead.

The research report surfaced late last week on the Electronic Thin Film lab of the Department of Materials Science and Engineering at the University of California at Los Angeles (UCLA), a known authority in material sciences. Author K. N. Tu investigated high-lead (90Pb10Sn) as well as eutectic SnPb (60Pb40Sn) and their exposure to fatigue cracking under thermal stress.

Nvidia’s use of high-lead solder joints and temperatures higher than 70 degrees Celsius are generally believed to be the reasons of the GPU failures reported by the company. The underfill is used to redistribute thermal stress: According to Tu, if “the underfill has [a] low glass transition temperature, it becomes soft at the device operation temperature, and the thermal stress will be taken up mostly by the solder joints.  The solder joint at the corners will fail first.” In each cycle, there is elastic deformation as well as plastic deformation.

The analysis is based on the thought that “when the total plastic energy or work-done to the solder is beyond a threshold value, it will crack due to excessive work hardening and sever plastic deformation.” The critical observation is that the plastic energy produced in the high-lead layer is about 100 times larger than in the eutectic SnPb joint - which leads the scientist to believe that “cycle times needs to fail” are “100 times longer” with the eutectic solder bump. Taking into account that he assumed an “ideal model” for his analysis, he concludes that “it is reasonable to say that it is at the least 10 times longer” in a real life model.

The translation is that eutectic solder joints may have a longer life than the high-lead joints, which would ultimately give such a semiconductor a longer life. We were not able to find out whether Tu’s research was actually commissioned by Nvidia or AMD/ATI, but the timing of the release clearly suggests that the results are aimed at shedding some light on the material issue in Nvidia’s GPUs.

There are also hundreds of YouTube videos on reflowing Nvidia gpu to fix your board, rather than paying $300 for a new one.

There are even Repair shops who offer the reflow repair Example

Chances are that it has overheated and had the problems detailed above. There is no solution but to replace the motherboard or to re-solder the graphic chip.
