How to Repair an HP DV9000 - Series Laptop

I received an HP DV9260US laptop as a high school graduation present. It worked well until 13 months after I received it, one month after the warranty ran out. To have it commercially repaired would cost on the order of $800, about the cost of a replacement laptop. As such, I decided to repair it myself. When one knows how to repair it, it is not that difficult of a task. The only part that could cause real problems is the problem of organizing the parts and screws. The organizational system I used was to place all the parts and hardware in a labeled ziploc bag whenever a part was removed from the laptop. As there are over one hundred screws, an organization system is critical.

Step 1 Symptoms

The symptoms I ran into were indicative of a video chip failure. My laptop became increasingly unreliable, and I ran into strange visual artifacts, such as flickering, oddly colored horizontal lines on the screen. After about two weeks of this, it refused to start up Windows at all. Another symptom is that it got very hot, even more than it used to, and this series of laptop is infamous for overheating. What was happening, I have since learned, is that the cooling system had become somewhat clogged with dust, and so was unable to cool the video chip adequately. This video chip, as well, was designed such that it has only a minimal tolerance to overheating. This confluence of variables led to the video chip being permanently destroyed.
