Good idea, but this is usually used as diagnostics method, to make sure that the chip is actually bad. Works best with most nVidia chips, all ati and amd chips, occasionally works with intel chips, but not very often and they don’t die often either, so blame the graphics, if present. What you do is not actually reflow, and flux is not needed actually, but you are fixing the chip itself, albeit temporarily. the balls in BGA array are quite reliable (if you manage to solder the chip properly during manufacture, which is great pain in the ass in electronics factories), what gets damaged are thin golden wires that electrically connects the chip with substrate, this is caused by long-term exposure to increased temperatures (naturally because of blocked airflow of fan), the difference in thermal expansivity of epoxy and gold makes all the magic, and the wear reduces gold wire flexibility, which will break. Heating it up to temps up to 450 Â°C for around 20s makes connection that will work again… maybe day, maybe week, maybe month, maybe year. Heat kills your laptop, clear your fans regularily…

picoman April 9, 2015 |
I have applied this method on my DELL inspiron N5010 (ATI RADEON GPU) after the complete operation my laptop worked perfectly.
But after one month it sows the same problem. I have done the same thing and it works again.
Till now i have done this 7 times and my laptop shows the same problem again and again in near about 1 month of time.Is there any solution to fix it permanently.
And if there is no solution than, can i completely remove the graphic card from the mother board.I want to know that after removal of GPU does laptop will work properly from video card or it will show any problem

Hello picoman,

hi picoman yep u jus remove ur graphic card. go with another nvidea graphic it may help.

Worked for An acer Aspire 9410 with scrambled picture/ three pictures of the same image mixed up. Made two heatsinks with copper and did the heatgun trick. Picture is stable now, and laptop repaired 😉

I’ve done the heat treatment on two Vaios and the cure is only temporary. If it lasts five months you’ve done really well. The temperatures were monitored after my DIY reflow and the graphics chip never went beyond 60c which is quite acceptable. Clearly the 8400/8600 chips have problems other than those you can solve with a reflow. When my nVidia chip failed after 5 months I had it replaced with an upgraded chip from a Sony specialist. That’s not cheap and you run the risk of paying some con artist for the sort of repair you can do yourself.
