Gateway NV50A DC Power Jack Repair

This NV50A gateway laptop came in with the classic symptoms of being able to hold the tip of the power cord at just the right angle to get it to charge and power the battery.  This means the dc-in jack isn't making a good connection and needs replacement.
The NV50a is similar to and uses the same power plug as the NV53A and some NV59 notebooks.
It uses a cable style dc jack that plugs directly into the motherboard but you can also buy the dc jack and solder a new one on the reusable cable.
Once torn down to the motherboard the ground wire was disconnected form the jack causing the failure (see picture).
Once the jack was replaced the laptop powers on and charge the battery again!

Samsung RV520 DC Power Jack Repair

This Samsung RV520 came in with a physically broken power plug.  The customer reported tripping over the power cord and breaking the connection.  As you can see in the picture the circular barrel that was there has been completely ripped out and needs replacement.
We perform the ac plug repair for $65 parts and labor +$20 return shipping if needed.
The RV520 needs to be completely taken apart to the motherboard and requires soldering.  If you don't have a quality iron and skills in soldering I would recommend not trying this on your own. 
The Samsung uses a 7 pin style dc jack that's soldered directly to the motherboard. 
Once replaced, the laptop powers on and works great!
