Question about Gateway MX6438 Notebook

1 Answer

I have a gateway MX6438 with a persistent DC jack problem. I had the notebook repaired and it started smoking on me not once but 4 times now. I've been told to replace the motherboard, but I'm hoping that there is a less expensive way to fix this computer, I like the features and don't want to give it up. Any suggestions? I can be reached at Charles B.

There's nothing cheaper than fixing the dc jack again, but if it's smoking it sounds like a sinking ship.

Motherboard swap is gonna be the only way out of this mess unfortunately.

My DC jack broke what should i do.


I am assuming you mean the DC jack on the motherboard in your laptop?
You can repair it yourself, or take it to a repair shop and pay to have someone do it.
To repair it yourself, you'll need:
1) A new DC jack (though sometimes you can fix the broken one)
2) The disassembly guide to your specific model of laptop. Google the phrase "laptop make/model disassembly" and one should come up pretty quickly. Guides are generally step-by-step with pictures included, and putting it back together is just the reverse of disassembly.
3) A soldering iron and solder. 15-30 watts for delicated boards like a motherboard. Once you've pulled your motherboard out, You can de-solder the broken DC jack from the motherboard (if necessary) and solder the new one on. DC jacks are generally 2-4 solder points and fairly simple to press back on.

Gateway MX8738 Laptop won't power on. The power adapter is putting out the correct voltage, but the computer is dead - no sign of life. This happened once before - repaired under warranty. This time I'm on...


Sounds like your power jack may be faulty or bad connection to motherboard unfortunately. The only way to truly find out is by disassembling the laptop. You'll have to do this at your own risk of course, and test the terminals at the power jack to see if you are getting power through them, if you are, then the trouble is deeper in the motherboard. If you are not, then here is a good article on how to fix the power jack:

Good luck.

No connection with the DC Jack on Gateway 3550GZ


It's time to take the computer to a qualified technician, for proper trouble-shooting & repair, because there are very-few "user-repairable" parts inside a laptop/notebook computer.

How do I fix a faulty DC In port connector in my Gateway laptop?


To fix it yourself you would have to take the laptop apart and remove the motherboard.

Repair costs could run you $50 and up depending where you take it.
