I actually managed to temporarily fix a laptop using a torch-like lighter directed at the GPU. This particular batch of laptops had faulty solder connecting the GPU to the board. The heat and cooling would eventually crack the solder and disconnect the GPU. I had nothing to loose and saw a video about it on YouTube. So I cracked it open and ran the flame around the GPU for several minutes. I eventually got it boot up and it lasted for another 9 months and then I needed to do the process again. I did it a few more times and probably got another year and half out of the laptop.
