Not until I came across this topic, that I actually known what is wrong with my IBM T40. .. All I knew it had to be an loose connection with a cable or a chip. Basically the symptoms I experienced is the LCD screen usually don't come on, unless Laptop is jarred, and even then it may have good picture for a little time but then the picture becomes dirty / distorted .. especially when the Laptop gets just a little jarred. And applying pressure just above where the GPU is located brings the picture back for as long as the pressure exists...
.. I guess it has already been said, this seems to be a famous problem with the IBM T40s.
I have read carefully the first post, I have some questions, sorry for my ignorance and I hope I didn't miss anything afterwards that may be of some answers here...
- For requirements an 1500W Heat Gun was listed, nothing was said about it needing to be VARI TEMP. I know in the details it was talking about gradually bringing the temperature up, I'm only guessing we need an 1500 Heat Gun with variable temperature ... like the one shown here http://parts.digikey.com/1/parts/986651 ... 1802e.html
Is it impossible to use safely an 1500W Heat Gun instead with like maximum two temperature variables like the Black & Deckers - http://www.blackanddecker.com/ProductGu ... uctID=2747
... And is there any place that shows how to fix GPU using simply an Soldering Iron - http://en.wikipedia.org/wiki/Soldering_iron
- Was the Aluminium foil tucked under the motherboard just a tad? or was it just hanging over the side of the motherboard ... All four sides?
- Was the heat gun always at an fixed location and pointing directly on the GPU chip or off on the side of it just a little? , was the gun height always the same and what height would this be? And was there an circular rotation like seen used on the youtube video?
- I noticed the image in the first post, it shows the heat gun slightly tilted, and not directly over-top pointing directly downwards. Hence one of the reasons for my previous question.
Again, I do apologize for my ignorance, and something I may have missed on this lengthly topic, I'm just somewhat worried, and with questions to be asked.
Much appreciate any assistance on this matter.
