What is causing the DV Series to fail prematurely?

I have seen dozens of 'solutions' and fixes for the DV series and none really address the root causes. Others damage or ruin motherboard. Below are some of the weirdest solutions I have seen: 1: Placing a penny between GPU and Heatsink. 2: Using a copper shim (only slightly larger in area than penny) 3: Excessive thermal compound 4: Wrong type of compound. 5: Placing a tea candle (in aluminum holder) on GPU 6: Putting Motherboard in oven 7: Pressing down on GPU real hard 8: Reflowing without flux?! Outline what each does and why it still fails later. 1: This will increase the pressure on the GPU when held down with 5 screws, a temporary solution, but does not remedy. Provides no greater heat dispersal and only transfers heat through penny. Metal fatique may damage the 5th retainer screw and not support the GPU. 2: Copper shim does the same as above. 3: Spreads heat over a larger area but does little to cool. 4: Does nothing 5: Can accidently cause more damag...

What Kills HP DV series laptops?

The number one issue with DV Series is: Blank or No Video displayed. The number two issue is : (tied) No Wi-fi or Continuous rebooting After repairing a number of HP DV Series laptops. 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. 1: Manufacturing - Hann-Starr Either the oxidation on motherboard or the Graphics Chips. Since the failure comes in both versions AMD and Intel lines. And in Intel and nVidia GPU's it seems it could be at the factory. 2: Distribution - nVidia Could 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. Then and only then did I notice there was no solder on some pads. So that points the finger to nVidia. Oxidation is the culprit since the solder balls are put on a ...
