Basically have a laptop that the graphics chip has come loose / lost connection (or something) and needs to some soldering / reflow done to fix it. Bit beyond me, but the 2nd post in this thread should explain it

http://h30434.www3.hp.com/t5/Other-Notebook-PC-Questions/HP-Pavillion-dv2000-2351nr-won-t-turn-on/td-p/61143

Took it to a shop and they said the prob was definitely the mobo/graphics but they didn't want to try and repair it, and instead wanted me to buy another laptop. Laptop is fairly old but need it fixed. Not sure how much a new mobo for these would be, but can't afford to spend much money on this.

Is there anyone in Chch who is willing to have a go at this for me? PM me if interested.

You might try Lounge Lizard Computers.

Just got them to repair my Xbox 360 which involved resoldering.

They are in Ferrymead.

Before you send it off for repair, I'd suggest removing the hard drive and backing it up.

There are plently of USB enclosures that will take a 2.5" hard disk drive. The price should be below $50.

Then it s simple matter of using a working PC, and USB port, to retrieve your files.

Don't worry that the USB enclosure is a one-time expense; It's definitely something you want to keep. Add a new 2.5" drive when you can afford it, and you have very cheap removable storage / a backup drive.

If you were after a replacement motherboard, you can try http://www.configraparts.co.nz/ I have a customers DV6000 here with a faulty board, and was quoted around $230 for a replacement.

Thanks, just contacted them - they don't reflow laptops.

Just looked on. Looking at $350 - $500. Not worth it, but thanks.

Does anyone have a heat gun?

If throwing it away is the only other option then Im willing to give it a go. Other option would be put it in the oven for a bit. Works awesome on graphics cards so can't imagine it would be much different on a mobo

Interesting! At what temperature? Have you ever tried it before?

From memory the graphics cards ive done were around the 150 mark and in oven about 5 min. It's easy enough to find the recommended temp (on the net I mean, manufacturers don't recommend this!) And yes i have before, one because it died and then the oven bought it back to life and the second went in twice due to water damage, wrapped in tin foil, to me its easier to see if anything fell off during the bake!

With a mobo though there could be to much plastic to be damaged...ram slots for one.

The only other option right now is replacing the mobo which I'm really not keen to do. Can't seem to find anyone who does reflows.

Something like this? (http://www.gpureview.com/how-to-fix-your-broken-video-card-step-1-preheat-your-oven-to-385f-article-798.html)

Does seem kind of dodgy but if it works it works. But if you have a heat gun / hair dryer (if that actually works?) then I'd trust you 100% to at least have a shot at it if you're willing to.

The mobo either gets thrown out, or it gets an attempt at being fixed and then either thrown out or fixed and saving me a crap load of money.

I've done a couple of PS2's that had the Yellow light of death as its known, and theres a method that sometimes gets them going again with a temperature controlled heat gun. They worked fine for a few months, then failed again with the same faults once they build up the heat again during high usage.

I have access to a heat gun, I would be happy to have a go reflowing your chip for you. Haven't had any experience with large motherboard chips though. Definitely no guarantees, if I completely wreck your computer it won't be my fault :) PM me if interested, I'll be free later this week

Thanks Forrest.

I'm not sure if Hueybot is still keen to do it, but if he isn't I'll definitely take you up on that offer.

Who's more confident at doing this? I don't really mind who does it, and I know neither of you can guarantee anything and that's no problem. Also since I'm not very tech savvy, would whoever does it be able to actually remove the mobo from the laptop as well?

Hey I dont have a heat gun, but can get a hold of one. Dismantling laptops is ok if your careful, putting them back together is fairly easy

I've taken a few laptops apart. They're a bit fiddly but generally OK if you're careful. I've experience soldering fine stuff but haven't done anything with BGA chips before so it would be a new experience for me.

Err well I'm happy for either of you to do it.

Whoever it is the less hassle for, let me know.

But still not that keen on taking the laptop apart myself, don't want to wreck anything before you even get the chance to try and fix it.
