ok here is my take:
1- chemical release is no worse from you painting your kitchen with oil base paint
2- heat gun wont tell you the temp the part is at
3- the oven method work if you take your time and do it well
i have posted here and on get satisfaction
the method in detail of how i did it here are the step i used
|well for those who doubt the "homemade reflow" i can garanty you it worked for me i had the same problem as the image posted here (green line and dot on the screen and been unable to run nvidia drive) i was also unable to get any image on the laptop screen without booting the laptop connected to a secondary screen.
*****THE FOLLOWING IS TO BE DONE AT YOUR OWN RISK AND IS NOT 100% GARANTIED*****
so basically here is how i did it:
1- open laptop and take out gfx card
2- unscrew hsf and carefully pry out hsf taking care not to squach or loose any of the blue thermal pad
3- clean gpu from the excess thermal compound
4- turn on oven at 190c "take note that the use of a oven thermometer is recommended as oven are not precise and you might have to play a bit with the oven temperature to get it close to 190c"
5- wait for oven to reach its temperature
6- while oven heat up prepare the gfx card by sitting it gpu upside up in a alumunium pie plate with little ball of aluminium to prevent it from sitting directly in the bottom of the plate also try to place the ball so that they touch the least amount of electronic part
7- carefully ounce the oven as reached its temperature put the plate with the gfx in the oven and close the door "this operation should be done rapidly as you dont want the oven to turn the heating element for to long to restablish its temperature"
8- wait 4 to 5 min and turn off oven "do not open door" leave it for another 4 min with oven at off and door closed, at this point you gfx should have been in the oven for ~9min at this point slightly open the door of the oven to slowly let the temprature fall for a good 30min **DO NOT TOUTCH THE CARD OR MOVE IT WHILE IT COOL** after that 30 minute periode fully open the oven door and wait another 15min before taking the card out of the oven, now be carefull even if the card might not feel that warm to the toutch the soldering joint are still weak and the card should be left for another good 15 min to cool down to room temprature.
9- you card is now ready to be reassembled i recommend you visit your computer shop prior to the whole operation and ask to get some ARTIC SILVER COMPOUND this will help eleviate part of the temprature problem *** carefull when applying the compound A.S. is conductive so care should be taken not to put any on the rest of the gfx and should be only a thin layer on the die itself ***
10- reseat the card in the laptop and reassemble the laptop, turn on the laptop and if all went fine you should be greeted by a fully working m1710
ps:mine as been working now for a full month without a bug playing a good 1 to 2 hours a day (r6 vegas2, graw, left 4 dead) and running some cad/cam around 4 to 6 hours (mastercam x3 and inventor 2009)
i also recommend you use I8Kfangui to monitor temp and set the fan to operate at slow as soon as it reach 40c on the cpu side and 50c on the gpu, i know this will shorten the battery charge but its that or a rapidly overheating lappy.
a little on how i decided to do my reflow i have based myself on how i do air tempering on metal part in my everyday job as a machinist.
hope this will help other as it did for me
also i would not advise people on spending there money on those service offered on ebay not because it wont work but i doubt the advantage of the 150$ spending, from the cooking it at home for 0.50c and +/- 1hr work
|for your own info and for others
in i8kfangui go to option:
temperature control --
select enable cpu temperature control and enable both fan and set it as follow
1 60c - 50c -slow - fast
2 70c - 60c -fast - fast
3 80c - 70c -fast - fast
4 85c - 80c -fast - fast
select enable gpu temperature control and enable both fan and set it as follow
1 50c - 40c -slow - slow
2 60c - 50c -slow - fast
3 70c - 60c -fast - fast
4 80c - 70c -fast - fast
cpu temp. offset 2c
gpu temp. offset 10c
thats about it if anyone as question post ill do my best to help
