I have a Cooler Master case: http://www.newegg.com/Product/Product.a … 6811119115

I'm pretty sure I hooked up all the little case/power button and lights to the motherboard correctly. However, the blue led around the power button stays on when my computer is turned off and when my power supply is completely removed. Is it draining power from the motherboard battery and should I be concerned?

Where else would it be drawing electricity from. Double check that you've hooked it up properly

Could it be getting power from static electricity? Try grounding the case and see if that helps.

Huh? Like black holes and such?

I pretty much can guarantee it will turn off if you try removing motherboard CMOS battery.

Exactly. This picture should clarify things.

Remove the outlet cord from the power supply. Then press the power button as if you were going to turn your comp on. That will drain the power from the capacitors. I have a green LED that stays lit even if the comp is off. That LED should run off of the cap.'s charges for quite along time.

just a theory, I'm only a Civil Engineer.

Possible, yes. Likely, no. That would be engineering flaw then.

i thought you was a firefighter? but yeah, if the case light being on disturbs you, try that or it's time for a ghetto mod.

And if all else fails, don't plug it in. I unplugged mine as I can't sleep with that tiny blue light illuminating my whole damn room at night.

When did it started happening, since Halloween?

I think a pic would be a good idea.

You could just unhook the LED power from the motherboard, it wouldn't affect the power buttons functionality as far as I know but I like to have things functioning as they should.

And my light doesn't stay on when the computer is off and I have the same case if that hasn't been made obvious.

Yesterday I plugged my iPhone into my PC, the PC restarted (fucking iPhone) I couldn't be bothered to go back into Windows because I was going to bed so I just turned it off. My G19 was fully lit up though, even the screen. I had to turn my PC on and go into windows to fix it.

This has nothing to do with anything but I felt like saying it.

There must be a huge capacitor somewhere. It probably goes off after a while.

The idea of any hi-fi system is to reproduce the source material as faithfully as possible, and to deliberately add distortion to everything you hear (due to amplifier deficiencies) because it sounds 'nice' is simply not high fidelity. If that is what you want to hear then there is no problem with that, but by adding so much additional material (by way of harmonics and intermodulation) you have a tailored sound system, not a hi-fi. - Rod Elliot, ESP

How long is a while? Cause it was still on after day 4 lol.

Yeah, that's what I did. The LED light doesn't affect the ability for it to turn on.

And the other lights in my case are red, and not blue and blindingly bright, so it made sense to disconnect it.

I have my power LED plugged in backwards. It goes off when I turn my computer on (only with the PSU connected though).

It can't be on after four days without a power supply. Unless you've got an AA-size battery in there somewhere, it is impossible.

Yeah, it's most likely taking power from an unusually large capacitor in your computer somwhere.

In my computer, after I take my PSU cable out, my computer can light all my LEDs, spin up my case fans, then it'll stop

No capacitor in a computer will light a blue LED for four days. A capacitor large as the whole power supply will let it shine for half an hour at most.

draining mobo battery. Take it off and if the light is still on call Mythbusters.

A mobo battery would only light a blue LED for about 10 hours.

Low voltage LED with the mobo battery & mobo caps feeding it can run days. Unless you have better explanation ie. the board being possessed.

Your standard blue LED has about 3-3.5V drop across it and draws around 20mA. The mobo battery is 3V and 220mAh. That's a bit under 10 hours of light before the voltage in the battery drops under what's required for the LED to light up. That'd also be quite noticable on the operation of the computer, as it'd forget the CMOS settings every boot. Capacitors in a normal computer are quite irrelevant. If you were to dump all the power in the 12V rail caps into the LED to discharge them, it'd still just light up for a minute or two.
