I have a gateway mx6448 laptop the power jack on motherboard has failed how do you test and can you get another one to solder in and where.. i know my cord is good i got 19.3 volts and says needs 19 volts....


Just to be on the safe side remove the main battery from the laptop since it is dead, in 50% of cases the laptop will run again. If there is no change the DC jack in the computer is the next likely suspect, most jacks that come loose can be resolded back on the motherboard but this no easy task. I usually go to www.ebay.com type laptop, make and model, and jack or DC jack, if you still want new. The laptop will require major dis-assembly and soldering work so if you attempt this be very careful and take your time.

Laptop won't power on with ac adapter or battery


Could be a combination of things.

1) Battery is low. Not enough power to turn the laptop on.
Caused by;

2) AC adapter has a plug on the end of the cable. The plug plugs into a DC Power Jack on the laptop.

The DC Power Jack is bad.

2a) The DC Power Jack has a bad connection to the motherboard, (Cracked solder joints), and/or the jack itself is bad.

2b) Center Pin is loose in the jack's mount.
The back of the Center Pin where it mounts has become loose.

2c) The plastic body of the jack, which composes the jack's case, is cracked. This allows movement of the Center Pin.

2b, and 2c cause a bad connection with the AC adapter plug.

No charge to the Battery, no power to the laptop.

http://www.laptopjacks.com/view_part/For-Gateway-MX6920-DC-Power-Jack-GW51425.html

[ If this is the case the DC Power Jack needs to be resoldered to the motherboard. The cracked solder joints need to be re-melted, (Reflowed)
Entire laptop needs to be disassembled down to the bare motherboard in your hand.
(No Processor, Ram Memory, or any adapter cards mounted to the motherboard. Nada)

OR,
The DC Power jack needs to be replaced.
This entails disassembling the entire laptop, down to just the motherboard in your hand. (Same as above)

The old DC Power Jack is de-soldered, and a new one soldered in place.

Very FEW computer repair shops have the necessary skill level.
They just want to replace the entire motherboard.
IF one is available.
More Ka-Ching for them also. ]

3) The AC adapter is bad.
Not providing power to the laptop, to charge the Battery, nor give power to the laptop without the Battery.

AC adapter cord from adapter to plug, which plugs into the laptop, (DC Power Jack), may have a break in it.

May be an intermittent contact provided by wiggling the cord.
If this is the case the wires have stretched, and broken.
Wiggling causes the wires to briefly touch, and make contact.

Where this cord meets the plug itself. A lot of times there is a break in the wires in this area.

Solution is to replace the AC adapter. There are universal AC adapters you can buy, or perhaps Gateway still has some for sale.

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.

Access to solder joint Gateway MX6440


Hello. I have seen this happen with all models of laptops. Too bad Apple has a patent on that magnetic power cord they use...

You can find all of the service and user manuals for your Gateway laptop here...

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.

You DO NOT need to replace the motherboard. Laptop jack can be replaced. This place can do it for you, you ship your laptop to them, they replace your jack, then send it back. It costs $99. A lot cheaper than a new motherboard! http://www.800tech.com/ And so you know, I am not affiliated with them in any way.
