Cant find my motherboard pin out,2817,2388344,00.asp?tab=Specs

With all due respect, you have the manual in front of you now

That is unless you started unplugging wires already, and didn't make notes, drawings, or take photos.

Let's use the Asus Essentio CM1630 motherboard for an example.
Couldn't find a CM1730, but that's OK. We'll use this one for a general example,

Put your mouse cursor in the middle. Now move your mouse around, using the Zoom In feature.

If this motherboard were mounted in a computer case, it would be turned 90 degrees to the Right.
Bear that in mind.

The front of your computer is the Front Panel.
The area of contact pins on the motherboard, that the Main wires from the Front Panel go to, is the Front Panel header.
Goes by many abbreviated names.
PNL 1, FP1, PANEL1, etc.
(Panel 1, Front Panel 1, Panel 1)

Go to the Top/Right corner of the motherboard photo. To the 6 Blue SATA connectors.
Immediately to the bottom of them, is a white Front Panel header.
Two rows of contact pins sticking up.

You need to make notes, drawings, photo, whatever; of where the wires from the Front Panel, go to each one of those pins.
(Some may not be used)

How to know which wires coming from the Front Panel, are the Power On switch wires, Power On LED light wires, HarDDrive activity LED light wires?

Remove the Front Panel from the computer. If it is Not just a cover, EASE it off just enough to look behind it.

You usually can follow the Harddrive activity LED wires.
Harddrive activity LED is usually AWAY from the Power On switch, and Power On LED light.

There's two wires down.
Now look at where the Power On LED light is. Can you see wires going straight to it?
Two more wires down.

From process of elimination, you now know the last two wires going to the Front Panel, are for the Power On switch.

(The Power On switch, is part of the plastic Power On Button assembly. If you look close at the Power On Button assembly, you can see this)

THAT sir, is the MAIN thing.
I can guide you where the other cables go, as far as power cables, and Harddrive cables, and Optical Drive cables. (CD/DVD drive)

If you have already disconnected the Front Panel wires to Front Panel header on motherboard; you get to play a game(?)

Power Supply plugged into power, use a small flat tipped screwdriver, and touch two pins at a time.
When you get to the two Power On switch wire pins, the Power Supply will come on.

Now it is a process of elimination.
Use an LED with two wires, to find out what the rest of the pins are.
The rest of the contact pins in the Front Panel header.
Grab the HDD LED light, or Power On LED light.
You're getting a new computer case anyway.

Touch two pins, and the LED light blinks?
That's the HarDDrive activity LED light, pins.
LED stays on?
That's the Power On LED light, pins.

Either of those LED's are dim, (When the Harddrive is active, or when the computer is on), switch the wires around.
You have the Positive ( + ) wire mixed up with the Ground ( - ) wire.

Moving on.............
The 6 Blue SATA connectors on the motherboard:
If you look close you will see;
Or it may be,

The Harddrive plugs into SATA0 or SATA1.
Just depends on what the SATA connector numbering starts with.

The main optical drive, or a single optical drive; plugs into SATA1, or SATA2.
A secondary SATA optical drive will plug into SATA2 or SATA3.

(Look at the SATA numbering above, and you can compare side, by side )

HOWEVER, the beauty of SATA is; that you can plug whatever you want to, in ANY SATA connector on the motherboard; and BIOS will find it.

Plug the Harddrive into SATA 3? No problem.
Plug the optical drive into SATA 0? No problem.
BIOS will find the drive with the Operating System on it.
The Harddrive.
Then BIOS will know the other drive/s are optical drives.

(Make sure in the BIOS Setup utility, that the SATA connector on the motherboard you are using, is Enabled.
Otherwise BIOS will Not see the drive)

What cable from the Harddrive, and optical drive; plugs into those SATA connectors on the motherboard?
A SATA data cable,

Note the L-shaped opening in the SATA data cable connector.
Lines up with an L-shape on the motherboard connector.
One example of a SATA connector on the motherboard is shown.
This one is an Open design. Your SATA connectors on the motherboard, will be a Closed design.

Between a SATA data cable connector, and a SATA power cable connector, the SATA power cable connector is larger in width.
SATA data cable connector has 7-pins.
SATA power cable connector has 15-pins,

See the SATA harddrive example?
Note the L-shape is pointing DOWN. It is this way EVERY time.
Now you know which way to turn the SATA data cable's connector, when installing. 'Foot' of L-shape goes Down.

How do i install the power supply

HP Support > Compaq Presario S6200CL Desktop PC > Main Support page,

Product information > Product specifications > Product Specifications > Motherboard specifications,

Scroll down towards the bottom of the page, for the Illustration and Photo of the motherboard,
(Motherboard layout / Overhead view)

1) Top of motherboard between Processor socket, and Ram Memory slots - CPU_FAN. Connect Processor fan.

2) Under Processor socket, and to the left of the Northbridge chip -> VIA KM400, (Under the aluminum finned Heatsink),
-> ATX12V.

This is where the 4-pin ATX +12 Volt power cable, for the Processor; plugs in.

[Note* Color of connector does NOT matter. Color of wires Does.
Also note the Lock on the side. When the power cable is deemed to be plugged in tightly, and correctly; the Lock's hooked end is over the Tab, on the motherboard connector]

3) CHA_FAN to left of ATX12V. (ATX 12 Volt)
Chassis Fan. This is where a computer case fan connects.

4) FRONT_1394a to left of CHA_FAN.
This is where TWO Firewire (1394a) ports connect to, from the Front Panel.
(The front of your computer is the Front Panel)

5) To the Left of the PCI1 expansion slot. (PCI and No.1 slot)
This is where a SP/DIF port connects to.

Not used in your setup to my knowledge. (From factory)

6) Below SPDI/F is AUX_IN.
Not usually used in a normal setup like yours.
(Meaning from factory)

7) Below AUX_IN is CD_IN.
This is where the small audio cable, for the MAIN optical drive connects to.
I state main because if you have two optical drives, one is Main, the other is Secondary.
IF, you have two; ONLY connect a small audio cable from the main optical drive, to this connector. NOT for the Secondary optical drive.

8) Under PCI expansion slot 3. (PCI3)
This is where the front audio (Sound) ports in the Front Panel, connect to.


EACH one of these USB headers is for TWO USB ports, in the Front Panel.
ONE of these USB headers may be used for a Card Reader.
A Card Reader uses two USB cables.

10) BAT1 is the CMOS battery

11) FRONT_PANEL header, is where the main wires of the Front Panel connect to.

Power On switch, Power On LED light, HarDDrive LED activity light, and Reset switch IF used.
It's a regular 9-pin HP, Front Panel header.

If you need the pinout let me know in a Comment.
You should have wires that end in a plug, from the Front Panel; and will need no pinout.

12) CLPWD is Clear Password. Leave jumper cap alone.

13) CLRTC is Clear Real Time Clock.
It is a reference to the RTC, or also known as the CMOS.
Leave jumper cap alone.

14) SATA 1 connector is where a SATA data cable plugs in, for the Harddrive.

SATA data cable connector has 7-pins. Between it, and the SATA power cable connector; it is smaller in width.
SATA power cable connector has 15-pins.

Note the L-shaped opening. Lines up on an L-shape on the Harddrive, or optical drive. (CD/DVD drive)

Note the red connectors shown below the SATA data cable.
These SATA connectors on the motherboard, are the Open design.\
Yours are the Closed design. Has a rim around it.

A SATA data cable connector that plugs into a Harddrive, or Optical Drive; usually is a 90 degree bent elbow,

SATA 2 is for a SATA optical drive.
HOWEVER, the beauty of SATA is, that you can plug whatever you want into ANY SATA connector on the motherboard, and BIOS will find it.

15) ATX_Power Connector:
This is where the 20-pin ATX main power cable plugs in.

16) Primary IDE:
This is where an IDE (PATA) flat ribbon cable plugs in, and connects to an IDE (PATA) harddrive.

According to the specifications you have a 120GigaByte
Ultra DMA - Harddrive.
That is an IDE unit also. (PATA)

Primary IDE is where your Harddrive plugs into.

Note the Locating Lug on the flat ribbon data cable's connector,

In this example it is on the Top/Middle.
Two 'ribs'.
Some are just a solid block instead of two small ribs.

It lines up with a Cutout, in the motherboard connector, or circuit board of the optical drive's cutout.

If this Locating Lug is missing on your cables, let me know, and I'll show you the correct way to plug in; using the RED stripe on the side of the cable.

17) Secondary IDE:
This is where an IDE (PATA) optical drive plugs in.

18) This is the power cable used for your IDE harddrive, and optical drive. A 4-pin Peripheral power cable,

Note the rounded corners. When installing this power cable, the rounded corners go UP.

Also known as a 'Molex' power cable.
Molex designed the power cable connector. (If memory serves)
The name stuck. Kind of like calling an adjustable open-end wrench, a Crescent wrench.

19) Floppy:
A Floppy Disk Drive plugs in here.
34-wire IDE flat ribbon cable.

This is the power cable used for it,

It is a 4-pin Peripheral power cable also.
Referred to as a 4-pin Small Peripheral power cable.
The one for a Harddrive/Optical Drive, is referred to as a
Standard Peripheral power cable.

This power cable is also used for a Card Reader.

If this information has helped you, please put a bunch of unmarked $5 bills in a mason jar, and bury it in the backyard. Some old biker will be by to get it.

Need wiring diagram for placement of the internal cables in Compaq Presario SR5410F

Top view photo of the motherboard, of an MSI MS-7525 motherboard made FOR HP by MSI, for a Compaq Presario SR5410F Desktop PC,

Also scroll down the page, and click on the + sign to the left of -
Motherboard Layout.

A) 24-pin ATX main power cable:

In the photo, look to the right of the Blue ram memory slots.

The Yellowish/Whitish connector to the right of them, with two columns of 12 socket holes, is where the 24-pin ATX main power cable plugs in.

In the Motherboard Layout it is marked by - ATX1

This is a general example of a 24-pin ATX main power cable, and it's respective connector on the motherboard,

Note the middle photo, and the Lock on the side of the power cable's connector. The Lock has a hooked end that goes over a Tab, on the motherboard's connector.

The Lock works like a see-saw on a playground. The top is squeezed in, and this brings the hooked end away from the Tab, in order to remove the power cable.
When assured that the power cable is plugged in tightly, and therefore correctly, the hooked end of the Lock will be over the motherboard connector's Tab.

B) 4-pin ATX +12 Volt power cable:

In the center of the motherboard, under the Processor socket, is the Northbridge chip. (Part of the motherboard chipset)
It is under a finned aluminum Heatsink, that resembles a meat tenderizer's head.

Draw an imaginary line up above it, in-between the Processor socket, and the aluminum finned Heatsink, and go straight LEFT.
See the whitish 4-socket hole square connector?

In the Motherboard Layout it is marked by - JPW1

This is where the 4-pin ATX +12 Volt power cable plugs in. It is power for the Processor. Has the same locking setup as the 24-pin ATX main power cable, and it's motherboard connector.

C) In the Motherboard Layout to the top left corner of ram memory Slot 1, (DIMM1), is where the Processor fan connects.

D) In the Motherboard Layout just below JPW1 is where the computer case fan plugs into. SYS_FAN1

E) In the Motherboard Layout - SATA1 - is where the SATA Harddrive data cable plugs into. (Below ram memory slots)

The SATA power cable from the power supply, plugs into the SATA harddrive. Note that the SATA power cable's connector, is longer in length than the SATA data cable's connector.

[SATA power cable has 15-pin. SATA data cable has 7-pins ]

Note that both cable's connectors, have an L-shape on the inside.

This is what a 4-pin standard Peripheral power cable looks like,

IF, your SATA harddrive has a provision for a SATA power cable, AND a 4-pin standard Peripheral power cable, ONLY use just the SATA power cable!

Otherwise you will burn up the SATA harddrive. May not happen right away, but I assure you it will happen!

[ A note on SATA.
The beauty of SATA, is that you can plug into ANY SATA connector on the motherboard, and BIOS will see it.

If you plug the Harddrive into SATA 1, or SATA 2, or SATA 3, or SATA 4, connector on the motherboard, IT DOES NOT MATTER.
BIOS will find the Harddrive, or optical drive ]

The Front of your computer is the Front Panel.
The area of contact pins on the motherboard, that the main wires from the Front Panel go to, is the Front Panel header.

In the Motherboard Layout illustration, the Front Panel header is down at the Bottom/Right corner, and is marked - JFP1.
(Right in the very bottom/right corner is JUSB2. JFP1 is right above it)

JFP1. Junction Front Panel 1.
9-pin header. Black rectangle.
5 pins on the Right side, 4 pins on the Left side.

The pins are numbered EVEN on the LEFT side.
Starting on the BOTTOM going UP;
Pins 2, 4, 6, and 8. There is NO Pin 10.

The pins are numbered ODD on the RIGHT side.
Starting on the BOTTOM going UP;
Pins 1, 3, 5, 7, and 9.

A) Pins 1 and 3 are for the HarDDrive activity LED.
(Light Emitting Diode, so it is a light )

Pin 1 is for the Positive ( + ) wire. If the HDD LED is dim when the harddrive is active, switch the wires around.

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

C) Pin 9 is N/C. Not Connected. 5 Volt power, and reserved for the factory to use.

D) Pins 2 and 4 are for the Power On LED.
Pin 2 is for the Positive ( + ) wire.
If the PWR ON LED is dim when the computer is on, switch the wires around.

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

I need a new internal power supply for my 2tb external its an Iomega prestige. I just want the part number for it so i can order a new one.

There is no internal power supply. The unit gets it's power from the computer. A USB port has 5 Volts DC.

Inside that external enclosure of the IOmega external harddrive is just an ordinary harddrive as used in a desktop computer. A SATA harddrive.

The harddrive plugs into a small circuit board with an interface on it, or there are cables, (wires), which come from the circuit board, and plug into the back of the harddrive.

It is this small circuit board that is usually the problem.
The solution to this problem is to simply just buy an economical external enclosure, and install the harddrive out of the IOmega into it.

Just one example from a quick search for an economical SATA 3.5 external enclosure,
A laptop harddrive is 2.5 inches across in width. 2 and 1/2 inches.
A desktop harddrive is 3.5),

Have additional questions or need clarification to what I have stated, please post in a Comment.

Does the toshiba satellite a135 s2276 accomodate a second hard drive?

You won't find internal room to place a second hard drive, if that's what you're asking. Most laptops simply do not have the internal space, especially thin-line units.

What you could do for extra storage space is purchase an external drive.
