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 ...
