![]() ![]() This does nothing for the corrosion/oxidation which is the ultimate issue. These units sometime wind up on eBay, Craigslist and other venues as 'working' units. They work (sometime) but the result is not permanent and usually used as a 'get it out' solution. The cost of all the tools and equipment to fix the DV series was about $100 max. Because I don't want them to fail, then blame me for not following directions. And people that want to learn how to fix them will have the option of getting a complete kit. This information will be posted in a technical manual. ![]() Will I post how to permanently fix them? Not just yet. And now repair them from various shops in the area as well as California, Ohio, Illinois and whoever can find my address or contact me. The training I received from my previous employers helped quite a bit. As well as the number of years that this problem has been known.īut it would require a good knowledge of solder's metallurgic properties, heat and manufacturing processes. ![]() Too many fabrication points for the same solder issue. But I don't believe that because the problem exists on DV2000, DV6000, DV9000, V6000, F700, C500 lines. I have heard claims from HP techs that nVidia got a bad batch of solder. ![]() Oxidation is the culprit since the solder balls are put on a the the GPU plant. Then and only then did I notice there was no solder on some pads. And in Intel and nVidia GPU's it seems it could be at the factory.Ĭould the transit time and shipping packaging be contributing to the oxidation on the GPU? On one unit after a number of reflow failures, I decided to remove the GPU and prepare to 'reball' the chip. Since the failure comes in both versions AMD and Intel lines. I wanted to isolate the problem and make it easier for me to fix, and have them stay fixed! So digging deep into them I can only come to a couple of conclusions of why they fail.Įither the oxidation on motherboard or the Graphics Chips. After repairing a number of HP DV Series laptops. ![]()
