Dim Power LED on Lain-Li

As most of you know, Lain-Li cases have two LED's on the front. One for Power (Blue) and one for HDD Activity (Red).

My old Socket A motherboard lit both up just fine. They are bright little suckers, they were casting red and blue light on the wall behind me :eek:

I put a new motherboard in this for the move to S754 about two moths ago, and just now I noticed that the blue power LED is really dim, less than half the brightness of the red one...
You read that right, I didn’t notice for two months (who examines their power LED?) but now that I know its like that, its bugging the crap out of me!

Any ideas on how to fix this?
 
I pulled the case over that was housing the old motherboard and connected the lights/buttons to the old motherboard and powered it up, both lights are nice and bright; I'm still seeing spots!
(It felt strange pushing the power button on one PC and having the other start :p )

So it must be the new motherboard :(
Is there anything I can do to fix it? I know dimming the HDD light would work, but I would really like to have the power light nice and bright...
 
First thing I would do is grab a DVOM (Digital Volt Ohm Meter) and check the voltage of the header. If you still have the old board running check the voltage on it too. Compare the voltages....

The easy route out of this is to go to Radio Shack and grab a 5mm blue LED and hook it up. I believe Radio Shack and Fry's carries a couple of different voltage ratings for their blue LED's, if you don't know the voltage of your header grab one of each if you can, try the higher voltage rated one first, then the lesser voltage one, if the 5 volt one is good enough stick with it, if it's too dim, try the other lower voltage one, if that one burns out you know your somewhere in between, lol. Always best to measure the voltage though.

I have had many different motherboards with many different voltage outputs on their headers. Probably just got a bad combo with your voltage output and your voltage input to the LED. I wish they had a standard for that kind of stuff.

Try searching the Electronics section of this forum, I know this has been talked about several times, if you need further assistance.
 
stop looking at it? probably no fix for it since the motherboard isnt putting enough juice to the leds.
 
Thanks for the help HippieCat, I'll check the voltage and report back with the results.

correction, LED (singular) the HDD LED is just fine :p
 
Since it's a power LED, it will be on whenever there is power to the Molexes.
So buy a 5v blue LED from ratshack and wire it to the PSU's 5v rail (Red wire on molex connectors)

Thats the current plan, I'm about to head down to Radio Shack to gab some LED's (more than one in case I screw up the first time :rolleyes: )

BTW, I checked teh voltage and its way lower than is should be on the 754 board (funny thing is, its a little on the high side on the Socket A board :confused: )
