HELP! front panel connectors

[kunka_boi161]

Hi I just got the case i bought today to replace my old dell otiplex 990 case. I need help with the front i/o connectors. can someone show me a diagram,photo or video on how to connect the front panel i/o of a dell otiplex 990 motherboard.

Just play trial and error until you find the right set of pins for the connectors.

 

Had to do that with an older xps system last month. It sucks

The problem is: when i plug in my power supply, the computer turns on but i have now wat of turning it off. is that normal when the front panels are not connected properly?

Post a pic of the FP connectors on the old case.

old one is the bigger one

Is there a model number for the motherboard stamped on it anywhere? 

 

That's a massive front panel connector, I'm betting there is USB and Audio in it as well.

I did see those, but they don't show a model number on the motherboard anywhere. Dell uses several major OEMs for it's motherboards and info can often be found from the motherboard manufacturer themselves, if you can find a model number.

well its a dell otiplexx 990 mini tower mother board. whats an OEM?

Just curious, but did you take any notes or pics of the motherboard setup BEFORE you took everything apart to reassemble in the new case?  That information would have come in real handy when putting things back together.

Whew, ok. An OEM is an Original Equipment Manufacturer. Dell doesn't manufacture, well, anything. I'm not even sure if they do any assembly in house anymore. Dell is just the company you bought the computer from, who has put together a computer package for you. The motherboards in them are actually manufactured by companies who specialize in electronics manufacturing, the OEM, like Asus, Foxconn, etc.

 

The company that manufactures the motherboard for Dell, the OEM, generally screen prints their name, a model number, a revision and some other information on the motherboard so that they can ensure nothing gets mis-matched anywhere along the process of making the motherboard or assembling the computer, and so that it can be replaced with an identical one if your computer needs to be serviced. 

 

A google search of that model did come up with one motherboard with a massive front panel connection like that, but the model number on it an OEM only Foxconn board, so that's unfortunately not going to be helpful.

 

I would not try to hook up the LEDs at this point, as they have a positive and negative terminal, and installing it backwards, let alone on the wrong voltage, would quite simply kill them. For power and reset, start on the far left side of the connector, using pairs of pins on the top or the bottom row of pins(ie. 1&2 or 3&4) and work your way across no more than 3 sets of pins or you might get into audio or usb territory and possibly fry that controller on your motherboard by jumping pins. Plug the connector on, and press the switch. If nothing happens, try holding the switch for a few seconds. If neither of those does anything, those pins are not your power or reset. If taping it restarts the computer, there's reset. If tapping or holding it shuts the computer down, there's your power pins. If you do 3 sets of pins on the top row, and 3 sets on the bottom row and get nothing. It gets a whole lot more complicated from there.

tried taking a pic of the tower before taking it apart

Just figured out the power switch! now its just the hdd light and hd auido

I wouldn't really recommend doing LEDs, the likelihood of killing them is extremely high. HD Audio looks like it's right next to front panel, before a couple of USB headers, however the front panel connection on the motherboard doesn't look to be keyed to match a standard HD Audio plug.

the hd auido looks similar to the int usb but i only have one slot so i need to choose between the usb or hd audio
