installing wrong front panel headers

post #1 of 10
Thread Starter 
Hey... I was putting together some old computers... I was very stupid to just install the front panel power..reset...hdd led...ect. in the fashion that my other motherboard ran in.... obviously they are not all the same but I had no labels and went the lazy route..

I am now, after alloting them to there actual locations(different then other board) stuck at this point

The power now does not work... I can not power the motherboard on... my next move is to use a different case... but theory persuades me to not try...did I , my motherboard did fry?

This is what I would try first making sure that all of the header connections are correct: Pull out the power plug from the electrical source then pull out the CMOS Battery from the motherboard for about 15 minutes then place it back in and plug in the power cable and hopefully the motherboard will turn on - should then default to the BIOS or show a CMOS error which is fine and you would only need to set the properties in the BIOS.

EDIT: What motherboards are they that you're having a difficult time with? Also what case has the non-labeled header plugs?

Try shorting the two pins for the power switch on the motherboard itself.

Take them all out and start with just getting the power switch to work. Remember that the white wire is the negative side and the colored wire is the positive. Plug them in and try turning the computer on. If that doesn't work, turn them so they face the other way (while still having white in negative/ground).

Also remember to have your PSU plugged in and switched on .

That's the problem the OP is having - identifying the header pins AND the unlabeled plugs from the case.

Thank you very kindly.... I will try those methods
What do you mean shorting the pins

If you know what pins on the motherboard header are the ON switch to get a screwdriver or small paper clip and touch them at the same time momentarily.

Yes. I know which ones they are... I was just lazy and didn't check online... pretty stupid but its not really a comperable computer nowadays... d865perl intel mobo... different header fashion than the a8n sli deluxe

It looks like there are alternate headers sharing the same pin configuration as USB. Double check that it's not plugged into the wrong socket.

Other than that, you should not have run into any problems with mis-pinning the front panel headers. Usually a problem like this is more common with accidentally grounding out the USB headers. Are you getting any standby leds on the board coming on?

Wouldn't hurt to do a PSU test either. Sometimes server boards (only supermicro in my experience) can actually be very stubborn to work with certain PSUs due to certain parameters in the shut down procedure.
