This is using your household oven as a rework oven. This how it's done in repair shops all the time. Except they have a better temp control. The nvidia chip has a problem in that some of the connection are on the bottom of the chip. This makes it very hard to remove the chip or resolder it.
I am absolutely astounded, but this worked! My Thinkpad was essentially dead (no video, would not boot), I followed the instructions from this video to the letter and now my Thinkpad is back up and running like a champ. This might seem crazy, but if you have nothing to loose, it's worth a try. Others have posted similar procedures but no explanations on why this works; my guess is that heating the board to 380F will cause the GPU to reset, thinking it's overheating, but this is only speculation.
@lenovomaniac Thanks for the reply. The curious thing is that I had my laptop for 3.5 years, and I've used my laptop day-in-day-out for all those 3.5 years and never had a problem until last week. So what caused the problem couldn't have been due to just a few week of extensive use. Do you think the same soldering issue applies to my situation as well and would does this mean for the permanence of this fix? Should I expect to be baking my motherboard again in a few weeks?
Definitely YES. Searching Internet I found that in this model this issue appear after 2 or more year.
I baked my mother board 3 times and after third i decide give it to service but no good because new motherboard cost about 450$ so in ma case i prefer buy new laptop. Every baking give life to my laptop for about 2 months.

It's becouse bad soldering. After few weeks of extensive work solder weaken and finnealy losse contact.
In your case solder responsible of power supply must affected this issue.
