I have placed this in the laptop section, but if it is more suited to the motherboard or graphics card section then, admins, please move it.

I have/had an asus g1s laptop, that was amazing to use and play games on. I bought it in a Best Buy in Las Vegas, so taking it back was not an option. It was also just over 2.5 years old. The problem was the dreaded nVidia problem, where the chip over heated. It did this since I got it, and unfortunately as it was my first laptop, I didn't realise there was a problem.
I have tried to have it fixed by heat soldering the chip back on, to see if that works, but the company that 'tried' were unsuccessful. When I say 'tried', I mean the looked inside and said "lets just leave this alone and go for lunch instead...eh?!"

That was the background to the story, here's the question:
Does anyone know what temp i should apply to the chip to 'reseat' the pins? Im going to try and do it myself, as I can't break it any worse than it already is. Its currently a write off, so anything short of setting it on fire will be an advantage. I was told that you can apply lots of heat to bend it back into shape and reseat the pins, as that is a major problem with the chips.

Has anyone tried this, or even better, been successful doing it?

Any help with this, or a point in the right direction is greatly appreciated.

Thanks all,

hey Ian_Eb,

it's a dedicated VGA. it's a 8600GT 256mb. Unfortunately, it's either Asus or a new laptop for me. Or as you say, a separate electronics company, but i don't think i'd bother getting it fixed if i can't do it myself. Paying to get it repaired and still use a faulty 'repaired' chip isn't really worth it. Almost better just saving up for a new laptop. But i shall certainly try to fix it.
 
thanks for that.
i also browsed youtube to see if anyone could show how they were doing it. I was surprised to find out home many people actually do this sort of thing!

Im slightly worried about the amount of plastic on the motherboard though. Will that not melt, or at the very least become brittle? Surely all the little plastic washers, connectors, etc would be ruined?

thanks again

I'd thankfully guessed not to put my whole laptop in the oven. Although I'm still unsure about the amount of plastic. The cpu socket at the very least!
I know its used to the heat, but I wouldn't have thought that high, and thanks to the heatsink, not that evenly high.

Cheers again

Thanks for that extra info. I have now stripped back my motherboard ready to go into the oven. I was worried about putting it into a warm over for 10mins, but the cold oven technique sounds like it should be more stable. I will give it a go tonight.
I was going to look into the reflow option, but to be honest, im far too lazy to look for a company and too skint to shell out money.

Cheers for the advice, i'll let you know how I get on.

i've got one of these, would that work?
 
As I type this, its currently in the oven. One thing I forgot to ask was...I've got a fan oven, should I reduce it to 215 degrees?
Any help from a budding gordon ramsay is also appreciated.
 
hey guys. here's an update. the oven trick didn't work.
i put it back together and it didn't change anything. although, in saying that, i put it back together before i read the post from Aod, about the solder not melting until about 230. the oven was at 210, and then for the last minute, went up to 220, but never reached 230.

i noticed that some of the parts to the motherboard went brown around the solder, but im hoping that was just flux, or impurities. the picture (which was taken on my phone) shows the little bits of solder that turn brown. these are just a few, this happened all over the board.

i will try again, as although Aod you have stated it's only wise to do it once, at the moment, it's a paperweight, and can't get any worse!

thanks again, and i'll give an update after i've stuck it in the over for the second time.

on a side note, i did like the look of the new HP DV6-2110 laptop, with i7, so i don't know if im going to unconsciously sabotage this asus!
 
So, here it is...the result.

So....it didn't work.

I tried again, this time getting up to 230, then holding at around 225-230 for just under 5 mins. I put it all back together, but still nothing.

I see from other posts/tutorials/videos, that people put it in for 6-10 mins, but am i really clutching at straws here?

I think it's time to look at a new laptop.

Thank you all for your help, advice and time in helping me try to fix this in such a unorthodox way. Maybe next time i'll buy it in Britain, so at least i can fight it legally if it's defective. Damn that 50% off saving on holiday!

p.s. Does your desk look untidy? Do you have lots of paper lying about, that keeps getting blown over by the wind. What you need is the amazing ASUS G1S GLOSS BLACK PAPERWEIGHT. A unique design of paperweight, it will hold multiple sheets steadily on a flat surface. Stocks limited to 1, so hurry with your offers!!! :)
 
hey,

yeah, it just didn't resolve the problem. the problem was always that the asus logo would come up on the lcd panel, the asus explosion would play, and then screen would permenantly stay off.

the only thing left i haven't checked is whether the vga out connected to a monitor might display something. if i was unlucky enough to fix the laptop and break the screen, but i highly doubt it!

cheers again for the help

im gonna punt the screen and bits and bobs on ebay and see if i can get 40quid or so. im really annoyed it broke, not so much that it couldn't be fixed.

but all is well.
i just went onto dell and bought a dell refurbished studio 1558 with i7 and other goodies for 400 quid. so i can't really complain now. and im gonna buy a nice vertex 2 ssd to replace the 500gb drive that comes with it, just so it's nippy.

thanks again everyone who helped trying to revive the asus. i'll know for future how to oven bake my laptop (when the dell warranty runs out).

thanks to jaffa cake makers, my laptop is now technically a biscuit, and not a cake, as it was baked twice. :D


cheers,

Hey,

if you are meaning the Dell as a replacement, then the spec is as follows:

Dell outlet certified refurbished Studio 1558
intel i7-720QM (1.6ghz)
4gb of 1333 DDR3 ram.
320gb hdd (7200rpm sata-II)
windows 7 64-bit home premium
8x-dvd+/- RW
integrated 2.0mp camera
chainlink cover
6-cell li-ion battery.

it cost 416, with 18 delivery, then vat on top took it to 511. but i'll get the vat back, as it's a 'business' purchase.

unfortunately, thats all the spec i have on it because it is an outlet one. not even emailing them got any more info!

i'll create another post when i get it, and add in a couple of pictures to show what condition 400 quid will get you. but for 4gb of ram and an intel i7, you cannae beat it way a stick!
