Question about Intel D865PERL Motherboard

1 Answer

Front panel plugs

The four sets of plugs have been taken off the motherboard and I can't remember how they go. One says, HDD LED (2 plug, red and black cable).
RESET SW (2 plugs, white and black). S/B SW (2 plugs, green and black).
POWER LED (3 plugs, green and black cables). Please help, as I think my motherboard might have taken a dive.

Motherboard User Manual For SiS965L?

SiS965L is a chipset designation, not a motherboard model number. That said, most motherboards do label the header pins for the front panel connections on the motherboard, though they are a bit small and sometimes are not adjacent to the pins themselves. The Power Switch and Reset Switch pins are not polarized, and when you determine which they are, the connector plug can be installed on them either way. The Power LED and HDD LEDs ARE polarized. The positive pin is marked with a "+" sign and the Green wore of the Power LED and the Red wire of the HDD LED must be on the "+" terminal.

The led on the front won't light, and I have power connected, but nothing. Is there a reset somewere?

I am assuming you are trying to power up an installed motherboard, based on the category selection. You say that you have power connected. That means that you have connected the 20 (24) pin main connector and the 4 or 8 pin CPU power connector to the motherboard. Have you connected the front panels controls to the motherboard header? There are connections for the power switch, power LED, HDD LED, reset switch (optional). They must be connected in order for the motherboard to start. THe HDD and Power LED connections are polarity-based, so if you hook them upo backwards, their respective LED will not light. The HDD LED plug is usually red and white with the red being on the positive (+) terminal. The Power LED plug is usually green and white with the green wire going to the positive terminal. The power switch and reset switch wires can be connected either way as they are not polarized.

How do I re-conect the power on and off switch to the motherboard?

They should be labeled. The Power switch plug should say pwr. The Hard Drive Led should say hdd, etc. Look on the motherboard for the inscribed label.

I'm having trouble with the pin out connections on a syntax motherboard. Where can i find a diagram?

Align the motherboard in your mind, so that we are both looking at it in the same direction;

Processor to the top, Ram Memory slots to the right, the four white PCI slots to the bottom.

The plastic front of a desktop computer is the Front Panel.

The area of pins on the motherboard, that the cables (Wires) from the Front Panel go to, is the Front Panel header.

The Front Panel header for the Syntax SVM266A is below the IDE 2 connector. It is labeled Panel 2

(Harddrive plugs into the IDE 1 connector, optical drive/s plug into the IDE 2 connector)

Panel 2 is mounted horizontally. It is parallel to the IDE 2 connector.

There are 4 pins across the Top row, and 5 pins across the Bottom row.

The pins are numbered. Even across the Top, Odd across the Bottom.

1) Starting from the Left side going towards the Right, for the Top row;
Pins 2, 4, 6, and 8. There is no Pin 10, just a blank spot.

2) Starting from the Left side going towards the Right, for the Bottom row;
Pins 1, 3, 5, 7, and 9.

A) Pins 2 and 4 are for the Power On LED light.
Pin 2 is for the Positive wire.

If the Power On LED light is dim, switch the wires around.

B) Pins 6 and 8 are for the Power On switch.

C) There is no Pin 10

D) Pins 1 and 3 are for the Harddrive activity LED light. (HDD LED)
Pin 1 is for the positive wire.
If the HDD LED light is dim when operating, switch the wires around.

E) Pins 5 and 7 are for a Reset switch, IF a reset switch is used.

As for a motherboard manual,

Scroll the page down to about 3/4ths the way down, until you come to the bold heading -

I have a new pc case on the front panel connectors their is one hdd led +- and one hdd led plug were do they go my case is a EVO LABS E-6690 BLACK/RED, 12CM LED FAN, INC DOOR AND SIDE WINDOW my mother...

Hi Badboy !

you can type the name on the motherboard on Google e.g : asrock m3a ucc pdf

You will find the pdf manual right away. On the 20 th page you will see how to connect the HDD led .I think the case should only have one led for the HDD if it has 2 leds just ignore it because the motherboard has only one place where you can put that led. Be careful and good luck !
