The front of your computer is the Front Panel.
The area of contact pins on the motherboard, that the main wires of the Front Panel go to; is the Front Panel header.
JFP1 is Junction Front Panel 1.
Better method IMHO is to state as Front Panel - Junction 1, so it's easier to understand.
Just some 'trivia' that I thought I would post to you.
Would however like to post;
Your body carries Static electricity. Static WILL fry out (Short Circuit), the delicate hardware components inside a computer.
Relieve your body of Static BEFORE reaching inside your computer.
(The Static? More than likely you won't see it, or feel it.
Your computer will,.....POOF! )
Computer ON a table, computer Unplugged from power, computer case open;
TOUCH an unpainted surface of the metal frame of the open computer case.
This action will relieve your body of Static.
IF you leave your computer in the middle of working on it, be SURE to Touch the metal case upon your return.
Since I'm here;
The method to test if the problem is the Power On switch, or the Power Supply; is to use a jumper wire on the 24-pin ATX main power wire's connector,http://support.gateway.com/s/MOTHERBD/FIC/105552/105552mvr6.shtml
This is an example of a 24-pin ATX main power cable, and it's respective connector on the motherboard,http://www.playtool.com/pages/psuconnectors/connectors.html#atxmain24
A jumper wire is used to BRIEFLY connect the Green wire, to ANY Black wire.
The Green wire is the Soft Power On wire. Abbreviated as PS_ON.
ANY Black wire you see is a Ground wire.
(And that goes for ANYWHERE in the computer)
The preferred jumper wire is a straightened out paperclip.
It is bent into a U-shape. Turn it upside down, and that is how it's used.
The top is wrapped a few times with black plastic electrical tape.
This taped area is for your fingers, and thumb to hold onto.
The 'legs' that come down on each side, are what is used.
One leg slides down, into the back of the ATX main power cable's connector, into the socket hole with the Green wire in it.
[The BACK of the connector is where the wires go in ]
Slides down RIGHT NEXT TO the green insulation of the wire, and goes down in far enough, to touch a female metal terminal.
All wires going into the 24-pin ATX main power cable's connector, end in this style of female metal terminal,http://www.mcmelectronics.com/product/28-9420&utm_medium=Affiliate&ref=cj&utm_campaign=CommissionJunction&utm_source=CommissionJunction
Looking at the middle photo of the Playtool link, you can barely see the openings of the female metal terminal connectors.
They look like small brass rings.
The other 'leg' of the U-shaped jumper wire, goes down into a socket hole, with ANY Black wire in it.
24-pin ATX main power cable is plugged in, just like the photo to the Right, in the Playtool link.
Power Supply plugged into power.
U-shaped jumper wire is used Briefly. No more than 2 seconds.
[The Power On Switch is a Momentary Contact Switch ]
What is the Voltage involved in the Soft Power On circuit?
5 Volts DC.
In comparison two D cell flashlight batteries produce 3 Volts DC.
Just want you to know, so you won't think I could lead you into being Shocked.
Not saying there won't be a small spark, though.
You may wish to wear a glove on the 'jumper wire hand'.
IF the Power Supply comes on, you have a bad Power On switch.
(You noticed before that, but this would have led you right to it)
IF the Power Supply does NOT come on, you have a bad Power Supply.
The Power Supply in your computer is an SMPS.
Switched-Mode Power Supply,http://en.wikipedia.org/wiki/Switched-mode_power_supply
Another widely used term for Power Supply is the abbreviation
PSU. Power Supply Unit.
It converts the dangerous high AC voltage, 100 to 240 Volts, from your home or business; into 3 low DC Voltages.
The dangerous voltage is contained IN the metal case of the Power Supply.
The 3 low DC Voltages are;
A) 3.3 Volts DC
B) 5 Volts DC
C) 12 Volts DC
Gateway Support > Gateway GT5056 Desktop PC > Main Support page,http://support.gateway.com/s/PC/R/1008835/1008835nv.shtml
In the list click on Components,http://support.gateway.com/s/PC/R/1008835/1008835cl2.shtml
In the list go to the bold black subheading -> Motherboards
Click on the blue title ->
105552 - Foxconn C51GU01Motherboardhttp://support.gateway.com/s/MOTHERBD/FIC/105552/105552nv.shtml
On this page click on -> Product Viewshttp://support.gateway.com/s/MOTHERBD/FIC/105552/105552tc.shtml
Now you can see where every cable goes on the motherboard.
Let's take -> Q - Front Panel Connector, for an example,http://support.gateway.com/s/MOTHERBD/FIC/105552/105552mvr18.shtml
Now you can see where every wire goes on the Front Panel header,
I don't know the color code of the twisted wires, that come from the Front Panel.
If -> I had to trace them, I would remove the Front Panel, and trace them to the;
A) Power On switch (PWR SW, or simply SW)
B) Power On LED (Light) (PWR LED)
C) Reset switch, (IF used) (RST SW)
D) HarDDrive activity LED (Light) (HDD LED)
If I were a betting man, I would bet the Red and White twisted pair of wires went to Pins 6 and 8. Power On switch.
Blue and White twisted pair of wires to the Power On LED. (Light)
Pins 2 and 4.

[I know. There's 5 minutes of your life you'll never get back.
I just posted the above, in case you run into this problem someday, and it isn't a loose Front Panel wire ]
