Below you can find some of the many laptop teardowns and repairs I have done over the years. Most of these repairs have been for friends and family. This is not an exhaustive list by any means as most of the time I do not take pictures during repairs.
A family member had asked me to look into why their HP DV2000 series laptop would not boot and this is when I first learned of the Nvidia GPU problems. The supposed problem is that balls of solder on the BGA based GPU begin to fracture over time due to thermal stress.
The solution is to reflow or reball the GPU. Without having the equipment or ability to reball a BGA chip, I decided to give reflowing a try. I shielded the area surrounding the GPU with aluminium foil then applied heat with a heat gun. It worked! I also applied better thermal compound the the CPU & GPU and then drilled some extra vent holes in the bottom of the case.
The laptop ran for many months following the repair but would keep failing. I would pull it apart again and again until I eventually got fed up. I scrapped it for parts in the end.
A friend of mine had asked me if I knew why his sisters laptop would not turn on, no output from the screen or POST but the fan came on. I immediately asked if it was an HP DV series laptop and shocker… it was. I told him how I had fixed many before and how sometimes the fix doesn’t keep for long. He brought it to school (St. Clair College), we booked a study room and tore the laptop down on our lunch break.
Some foil, heat gun and a few mins later we had it up and running again. As far as I know it still runs to this day. It does run a little hot and the fan is spinning at a much higher rate then usual but it was better than nothing. This is one of the few DV series laptops where the reflow fix continued to work for me.
The power jack on this laptop was in very bad shape and in desperate need of repair. The jack had previous problems and I fixed it by resoldering to the PCB and applying some epoxy. Later the jack suffered more damage from the user as the the center pin (tip) had been broken right off. Because of this the unit could no longer power up or charge the battery.
A jack replacement was needed and so I ordered the needed parts off of ebay. Pulled the old jack out and soldered the new one it. Worked out perfectly! I hate when laptop manufactures solder the DC jack directly to the board. Eventually the wear and tear becomes to much and it becomes a single point of failure. Better designs have the DC jack soldered to the PCB via wiring, virtually eliminating this stress point.
