Question about Computers & Internet
I disconnected the front panel leads from the mobo and looking for a pin-out diagram so i can reconnect them properly
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:

What is the Series of the Unit? Most of these diagrams are available on the Manufacturers Website for just this reason, But I would need more information on the Model and Series of these computers to give you the URLs for this
