Diagram put back together


Hello
Not to much information from you . Here is a E-Machine assembly for the motherboard .
The power switch is a 2-wire connection to the Motherboard. The 2 pins on the motherboard it connects to will be labeled something like PW. The polarity on it doesn't matter. There will also be a power LED connection. Usually those wires are green and black. Green is positive. There's also a hard drive activity LED with (usually) red and black wires. Red is positive. Hopefully that polarity will be marked on the motherboard. If not, try it one way and if the LED doesn't light up, try it the other way. The power (green) LED should be on whenever the PC is on. The hard drive (red) LED will be on whenever the drive is being accessed. There might be pins on the motherboard for reset. Some computers don't have a reset button. In that case you wouldn't connect anything to it. If your case does have a reset button then connect the wires to the reset pins on the motherboard. Polarity doesn't matter for that.

Hope this helps

How to connect power switch,led,reset switch to MSI MS 7548 (aspen) Motherboard...


MSI doesn't have information on the 7548, since it was made directly for HP. Here is a diagram of another MSI similiar and usually they have their pins on their jumpers pretty much the same. You would use JFP1, And Pin's 1&3 would be the hard drive, 2 & 4 would be the LED, 6 & 8 would be the power switch, and 5&7 would be the reset switch. I know your motherboard is setup slightly differnent, but your JFP1 should be in the right hand corner all by itself.

I'm attaching a diagram of the layout of a similiar board

I need the wiring diagram for emachine model D6405


Usually it is in very small print right on the motherboard next to the pins, use a flashlight and/or a magnifier to see what order the pins go in. The hard drive light will say HDD, power will say PWR, etc.

I don't know how to plug in the wires for the ASUS a8n sli deluxe motherboard


Here is the manual for your motherboard (since describing a diagram probably isn't very useful...)
http://dlcdnet.asus.com/pub/ASUS/mb/socket939/A8N-SLI/e2024_a8n-sli.pdf

You want to look at pages 27-35, they describe what you need to plug into the motherboard. Basically make sure you have connected:

1) 24-pin power cable (from power supply)
2) 4-pin power cable (for CPU from power supply)
3) Any case fans with 3/4 pin connectors.
3) hard drives (SATA or IDE)
4) USB front panel ports
5) Audio front panel ports
6) Case plugs (power LED, hdd LED, power switch, and reset switch).

I need a diagram of the atx pwr connector for an ASUS P4V8X-MX


If you mean power to the devices themselves, the 4-pin connectors coming from the power supply plug in to the drives. The red wire is +5 volts, the yellow wire is +12 volts and the black wires are ground (earthing) connections. IDE hard drives and CD drives use the same connector. SATA drives may have that same connector as well, but most use a different style. SATA-ready power supplies will have 1 or more plugs available. Adapters to switch from the 4-pin IDE plug to SATA type are available for supplies that don't have the right connector.

If you are asking what power pins from the mainboard power supply connector are supplying power to specific controller parts on the mainboard, that kind of detailed information is not available. Mainboards manufacturers do not supply circuit diagrams or repair information. They simply replace any boards that fail while still covered by the warranty, and expect you wil just buy a new one if the warranty has expired.

Much information about ATX boards including the power supply cable pins is found here:

Installed an Upgrated Mother Brd,in my Hp Desktop Tower,but the power Switch receptacle in the New Mother Brd has 16 pns


You need to track the wires from the case front panel to thier locations: one will be your power switch, one your reset, one hard drive activity light, and one your power light. You want to note and label which light or switch they go to then go to the new motherboards manual and plan which wires need to go where.
the front panel switches : reset and power switch- these are momentary switches so it doesnt matter which way they go.
hard drive activity and power light- these should have a colored wire and a black or white. the colored wire will be your + side.

How to connect front pannel


How about a picture? Pg. 46 in your manual.
Need manual, download from Intel. (Click on link).

Intel RC440BX Specification
Pg. 46
Basic rules case wiring. The color black is considered ground -. Power wires + can be any other color including stripped wires. (This is standard but case Mfg change to their own specification).

Pin 1 is + power for LED Hard drive green LED, Pin 2 is -/ground for Hard drive LED.
(Pin 3 is + power for LED Hard drive yellow LED, Pin 4 is -/ground for Hard drive LED).(See more options on pg. 47).
Pin 5 is + power for case On/off button, Pin 6 is -/ground On/off button.
Pin 7 is + power for Reset Switch, Pin 8 is -/ground for Reset Switch.
Once positive & negative pins has been located each connector follows in suit.

The Intel RC440BX front case connector is in an odd location.
The user will find it hard to connect front case LED connectors while the board in installed into the case.

Good Luck!
