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.

Need wiring diagram for ms-7142 motherboard... fixing a friend's computer, but they unplugged the wires that run to the front... therefore the power and LEDs don't work...


The connector bus where the front wire connections go, is usually marked. It's usually two rows of pins sticking up. You should be able to determine where the power wires connect. One pin will say PWR. The second pin you need is either next to, or across from that pin. The LED pins are labled too. Keep in mind that LED's have polarity. That is, a diode [light emitting DIODE- LED] only works one way. It's a one way "Valve" for electricity. So if you determine which two pins are for the power light and you connect them, it still may not work. Just reverse the two wires to the two pins and it should work.
I can't imagine that the MSI web site doesn't have the pinout for this board. It would be worth a look if you're not sure of what I'm saying here.

I have an emachine t3104 and upgraded the memory the wires from the front of the case became un attached now I dont know where they connect on the motherboard they are black and whitebbgreen and white and...


That model has a MSI K8MM-V (MS-7142-010) motherboard. Mostly likely you knocked some of the computer case wire connectors off the motherboard. These connectors usually include things like the case speaker, indicator for your hard drive operating, etc.

You may want to do a websearch for the manual, which will show a detailed breakdown of these wire connections and how to reinstall them.

T6410 EMACHINE TRYING TO CONNECT START BUTTON


The motherboard in your computer is an MSI MS-7145, which is also called RS480M. You can download a copy of the manual here. The front panel connections are on page 2-20.

Looking at the header JFP1, pins 1 through 9 (odd numbers) are the front row, pins 2 through 10 are the back. Pin 10 is the missing pin. The power switch connects to pins 6 and 8. The power LED connects to pins 2 and 4. The HDD LED connects to pins 1 and 3. The reset button, if used, connects to pins 5 and 7.

I need to know the sequence on how to connect my Power LED, Reset Switch, HDD LED, and M/B Switch up correctly. I have an MS-7142 VER:1 Can you help me?


Hi carlmtclem, your not alone when it comes to hooking up the right led connector to the MSI MB. Firstly, you need to know what wire color is positive & which is negative. Most commonly the color white is ground/negative. Wire colors do vary from case to case. So look at your case led wires. Which ever color is common for each 2-pin connector, is negative. (Except the speaker wire).
All other colors are positive.
(The speaker wire color for negative is usually black & red is positive).
Your MSI board has two separate sets of pins.
JFP2 is used for the speaker only. Do not connect the power led there.

Pin one for JFP1 is shown in the manual. Pin 1 is positive & pin 3 is negitive for the HDD-LED, ECT.

Thats it.
Need more information?
Post here.
Good luck carlmtclem!
Thank you for using fixya.

Front panel leads Emachine model T2862


E-machine model T2862 pin-out for the 10-pin front panel header is screen-printed on my Emachine's motherboard, but is so small and far away from the actual pin location, that it is likely being overlooked. If looking into the computer case from the side where you remove the panel, the header looks like a row of four pins with one missing at the farthest right pin location, and a row of 5 pins underneath that, with the fifth pin directly below the missing (key) pin in the row above it. Starting on the first row, you would install the 2-pin connector from the front panel labeled "Power LED" to the leftmost and 2nd from the left pins. (You may need to switch it around to get it to work as the LED is polarized. You will know as soon as the system starts to boot up if it is on properly, as this light burns constantly if the unit is on.) Then, to the right of that connection, you would connect the 2-pin connector labeled "Power Switch" to the 3rd and 4th pins from the left on the first row. (It does not matter which way around this connector plugs on, as all we are really doing is allowing the front panel button to connect these pins together to turn the system's power supply on when you press the button.) OK! Drop down to the BOTTOM row of pins below the first row. To the leftmost and 2nd from the left pins on the second row you will install the connector labeled "HDD LED". (Again, you may have to switch it around to get it to work since it is polarized. You will have to watch the system boot up and as the hard drive is accessed, you will see it blinking randomly if it is connected properly. NOTE: You will not damage anything if this or the power LED is hooked up wrong. They simply will not function. So don't fret, just switch them around.) Next, the header has room to connect a reset switch if your system has one. (Mine does not.) You would install the 2-pin connector labeled "RESET" to the 3rd and 4th pins from the left on the second row of pins. (Again, this is a connector that works fine regardless of which way around you install it, as it simply lets the reset button connect these pins to reset the system when the button is pressed.) Finally, you will notice one pin is left unused below the missing (KEY) pin. As far as I know, this pin does nothing, but is likely a ground or maybe a source for DC power as I have seen before. The unused pin above it is for manufacturers who make one connector coming from the front of the case which is pre-wired with all these functions, so the connector (usually with 10 total possible wire locations) can have that one location sealed or capped to prevent someone from installing it the wrong way around and potentially sending voltages somewhere they shouldn't be going, or causing something to not work properly. I made a quick pic in MS Paint below for better reference:
