You should go buy a new laptop. It is the Nvidia Chipset. He said it needs to be Reflowed using a BGA machine. That is still not a permanent fix for this problem if it fixes it at all. Its about a 50/50 chance of success. It can still overheat and fail again in a month, a week, a year. No way to tell for sure. Dont buy a new board on ebay. Just suck it up and scrap it.

I work on laptops and board repair all the time. This is such a major defect we would not even warranty our work on boards that contained any of the defective chips.

Sorry buddy.

An easy way to think of this problem is the Xbox 360 RROD. It is the same type of failure. The Chipset overheats, solder gets too hot, chip separates from board. You can reflow it but it will not fix the core issue inside of the chipset itself. Bad transistor packaging.

Last ditch attempt, throw the mobo in the oven for a bit and see what happens.

OMG RROD brings back memories. or should i say nightmares. I do actually still have 1 old xbox i repaired RROD that lasted for years luckily but like you said some i would have to repair every 2 weeks or so.

What a terrible idea. lol He would do better with a blow dryer or the "penny trick". 2 more terrible ideas but if worse comes to worse it wont hurt. Get a small thin piece of metal and place it on top of the chipset. Then screw the heatsink down on top of the metal shim. This will apply an extra amount of pressue on the chipset. If you are lucky it will seat the chipset down some and you will regain video. This again isnt the best of ideas but I have proven this to work. Put heatsink grease on top and bottom of metal shim.

the blow dryer and over trick may heat up the solder on the bga chip but it can also heat up the solder on other components. A blow dryer can blow the tiny chips off the board. Not the best solution. Good luck or just go buy a new laptp. CQ40 is a terrible laptop anyways lol

I know its a terrible idea but theres really nothing to loose, I suggested someone bake their dead SSD too (although that had a little more proof that it would actually work) again nothing to loose so why not?

Now imagine that same problem with a laptop or desktop. Same nightmare different form factor.

I know thats why i laughed. Its terrible but wth. Its not like you could break it more. lol I hope you didnt take my statement the wrong way bro. All ideas are good ideas except the bad ones. lol In this case there are no bad ones.

Thank you! It have to be very thing but strong. A penny is too thick but I tried it once and got that to work too. Its hard to get heatsink down and it will bow your board. Thinner then a penny and just big enough to cover the chipset die. Good luck.

It's all good You could also go get some professional reflowing tools and do it the right way, probably better to just cut your loses though XD

A BGA machine is 50k. lol A used solder pot is $4500. Trash it, shim it or bake it! lol

Best idea was to replace it with a new notebook, or even a tablet, it's not worth the trouble or time trying to fix it.

But I have a 100k notebook :P

I agree. A Cq40 was a cheap low end laptop in the first place. Trash it and get a new one. The tech stuff just flows out sometimes. lol
