It uses the standard averatec five pin, 2.5mm dc jack.
After the jack was replaced the laptop powers up and charges the battery. The picture shows the cracked and broken dc jack.

Gateway NX570X/MA7 DC Jack Repair


The gateway MA series laptops are ones I see all the time in the shop. MA2, MA2A, MA3, MA7, and now MA8 are all problematic with the power jacks.
They use a seven pin, 2.5mm dc jack and either 19v, 3.42a or 4.74a power cords/ac adapter.
This MA7 didn't show any signs of life when plugged in and I couldn't get it to power on before the repair.
Once the jack was replaced the laptop fired up at the board level and when put back together.

The 7818 uses the same six pin, 1.65mm dc jack that many acers use.
The laptop is fairly easy to get apart and needs to be completely disassembled down to the motherboard to get to the dc jack.

Dell Latitude 100L DC Plug Repair


The dell latitide 100L is a business laptop from dell. It is identical to the inspiron 1150 so it will have the exact power issues as that common model I see.
This 100L showed no signs of life and wouldn't power up before the repair. After I got the laptop apart I could see the dc jack was fine but the power filter next to it was bad. Adding solder to the power filter is like reconnecting the link in a chain. If it's broken it can't power up, but once solder is added the flow of electricity is restored.
The laptop now powers up and charges the battery.

hp dv7 laptop jack replacement


The dv7 is hp's 17 inch lcd media notebook/laptop/desktop replacement. Features like hdmi, e-sata, and beautiful 17" LCD make it one nice looking and performing laptop. This dv7 came in my shop with no signs of life. Plugging in the power cord and manipulating it in any direction would not get it to power up but the owner reports it worked on battery until that drained.
The dv7 uses a cable style dc jack that plugs into the motherboard vs. the traditional soldered on jacks.
After replacing the jack the laptop powers up and charges the battery!

Dell Inspiron 6000 DC Plug Replacement

Yet again, another dell inspiron 6000. This is an exteremly common model in here over the last three years. I'm sure dell made thousands and thousands of these popular 15" laptops so that could be part of why I see so many.
This one had the classic hold the power cord in just the right way or it would shut off or not come on in the first place.
It uses the standard circular dell nine pin jack they still use today.
Both of the voltage pins on the jack were oxidized a blackish color and the jack needs to be replaced.
The video below is the symptom of being able to hold the power cord in just the right way to get it to power on. As soon as it's moved the laptop shuts off. I could barely get this one to power up.
