    can't find i/o header with marking you indicate. Tried the connector on far right (as you're looking at the kybd/mouse connectors in the back - the header next to the far right slot...Tried every pin, one to the other but no good. Tried another header (again, no silkscreen markings) next to the primary IDE connector... no good. Thanks for trying though.

    awesome... thanks for the user manual. yes, pg 68 matches the mtb i
    have. I tried shorting pins on that puppy already... no luck. The
    front panel switch connector actually cables to a small pcb that has
    two usb ports and a headphone jack. The actual on/off switch in the
    front of the cabinet plugs into the small pcb. There is no active
    circuitry on the small pcb so it could be a passive pass through... I
    will try messing with the headers on the small pcb and see what
    happens. As a last resort, I may have to tear out the power switch
    from the cabinet and mickey mouse it that way. Thanks for your help.

Try the owner's Manual, page 68. Hopefully that's an accurate match to what you have. If the diagram is confusing, let me know what you're trying to do specifically, and I may be of more help.

Please rate if this works out!

    What is the problem with the front panel connector that you can't connect the front panel plug into it to use the power on button?

    If you could check which wires go to the front panel button for power on, you could backtrack to the exact pins that are used for power on.

    I believe the socket you're looking for is labeled front panel switch connector (J60H1), at the top right of the diagram.

Alright i know where it is but it is kinda hard to explain without a picture of the motherboard, ok look at the far lower right side of the motherboard you should see something that says i/o header or fpanel, you can take a small flat head screwdriver and run across that and the computer will turn on, be sure to take note of the 2 pins that turn the system on and id suggest marking them with a marker or something on the board for future reference

Dell motherboard diagram of wiring and front pannel connectors


most front panel connectors with a 4 x 5 pin configuration are intel compliant, and are all the same.
The "nine" pin is missing, and is the "KEY" to orientation, no matter which way the pins are situated on the board.
1 3 5 7 X
2 4 6 8 10

1= HDD LED+, usually green
3= HDD-, usually white or black
2= PWR LED+, usually red
4= PWR LED-, white or black
These are polarity specific, and must be connected to the proper + and - terminals to work properly

5= RESET
7= RESET
9 is missing, can be used to determine location of other pins
6= PWR
8= PWR

Thes are momentary contact pins, can't get them backwards

Pins 6 and 10 are jumped together in the Dimension 2400.

If you carefully take a screw driver and short the two power switch pins together it should start. Did it work before you cleaned it? On the connector itself it should say power sw.

How do I plug the Power Button wire into the motherboard?


Printed on the MB
HD LED +1 -3
PWR LED +2 -4
RESET 5- 7+ (Why the changed order? & there's no reset button on this computer.)
PWR ON +6 -8

There are nine pins with a little triangle pointing at one and a 2 next to another.
The pins on the MB look like this:

2ndpin
. . . .
. . . . .
1st pin


Found some info on the 506GR. Unfortunately Gateway is keeping the service manual a big secret.

This will help. Thanks please keep updated. please do rate the solution positively .Thank you for using Fixya

I have 3 wires on my pc and i dont know where to connect them on my motherbaord - the wires have writen on them "HDD LED" "PWR LED" "PWR S/W" can any1 help me?


Hi Dan,
The wires are from the front panel. HDD LED which causes an led (usually red) light to turn on when the Hard Drive is active. The PWR LED turns on an LED light (usually green) when you turn on your computer. The PWR S/W turns on your computer when you press the on button of your computer. The front panel connector riser is usually located on the bottom right of your computer. They fit on little pins. Unfortunately there is no standard, so connections vary. Sometimes the pins are labeled on the motherboard. . Check your manual. For more info do a google search for "Motherboard front panel connectors". Hank

Motherboard made October 10, 2003 for a Dell Dimension E521?

http://support.dell.com/support/edocs/systems/dime521/en/SM_EN/index.htm

(Technical Overview, then click on System Board Components)

If this problem is directed to the Front Panel connector, info is hard to come up with. (Usually stamped on motherboard next to the connector.

The connector that is rectangular in shape, on the outside edge of the motherboard.

Right below the ram memory slots, and one of the SATA connectors. Wires from the Front Panel of the computer tower, connect here)

There are 2 rows of pins in that connector. Look on the motherboard real close, for a number 1 stamped near that connector. This indicates the Number 1 pin.

Right across from Number 1 pin is Number 2 pin. (Going across the Width of the connector)

If memory serves Pins 1 and 2 are for the Harddrive Activity light. (HDD)

Pins 3 and 5 are for the Power On light. (Pwr LED)

Pins 4 and 6 are for the Power On switch. (Pwr ON)

Pins 7 and 8 are for the Reset switch (RST)

New motherboard


You don't say what case you are using. If it is proprietary and the front panel header is all in one connector, you can carefully back the connector pins out of the block using precision screwdrivers. I keep a bunch of two pin connectors from junked machines so I can create individual connector sets when changing motherboards (eg, PWR SW, PWR LED, HDD LED and RESET). This also requires that you know the pinouts of both the old board and the new one so you can get everything connected properly.

Very doubtful you will ever find an adapter to change from one front panel block to another.

The 9-pin connector probably uses a spacer pin between the legs of the PWR LED, while it seems the 6-pin does not have RESET.

Have Dell E210882 MTB and need pwr-switch pin locations


No, don't automatically assume the mobo is broken. Look closely at all the pins. There should be a 4x2 rectangle of pins, maybe coloured. They'll say things like 'PWR-SWTCH' and 'çPU-LIGHT'
Connect those up, and your mobo manual should have specific details on what goes where.

Connecting the case to my motherboard


Pin arrangment is Industry Standard Architecture.....

pwr led pwr sw N/C
X X X X O

X X X X O

hdd rst N/C

translated this is top row left to right ...... power led, power switch no connection

Bottom row is left to right........ hard drive, reset, no connection

Note: not all computer cases have a reset button, also the connectors for power led and hard drive produce a light, if the light does not show, power off the pc swithc the cable rooun 180deg on the connector pins and reconnect.

Gigabyte GA-8INXP Motherboard Problem- front connector pins


If the wires from the reset switch is white/blue the blue wire is positive, Hdd red/white red is positive power Green/white Green is positive etc. The wires on the speaker connector will be red/black/black/white - red is positive. The colored wire is always positive. On all GA mb's the positive connection is always towards the back of the MB and are marked with a + on the base of the pin as you can see on the photo. Hope this help.
