[Urgent] Boot a Motherboard with No Power Button

Ammonite · Jan 30, 2012

I have no case and I want to test my mini-ITX designed Intel Desktop Board D525MW.

No idea how to do this. The power supply makes the light on the board go on, I've tried touching the red on / off pins together and jump it but it doesn't work.

Going insane. Urgent help needed, I don't have a lot of time to have it sitting around on the desk.

You need to jump the green with the ground (black) googling for pic

Ammonite · Jan 30, 2012

That picture makes no sense to me. I have a 10pin PicoPSU that is nothing like traditional power supplies. I thought this has to do with pins on the motherboard?

m1dg3t · Jan 30, 2012

Sorry 'bout that, let me google an image for a pico PSU....

Didn't read :laugh:

I think your confused here he wants to power on the system not test if the psu works which might be a good idea anyway considering it wont turn on

momentarily touch the two red pins with something metal to jump them if it dont turn on something else is wrong

Uh oh.

I have been doing that using a screw driver but nothing has been happening. Does this mean I might have a broken board? D:

You got me! Was being lazy and just read the thread title :laugh:

O/P you got your answer now

Edit: Perhap's you have to maintain contact longer for it to BOOT up?

Batou1986 · Jan 30, 2012

@ midget, ive done this more times than i can count

@Ammonite try re seating the RAM or just 1 stick at a time, removing all add in cards, clear CMOS.

According to spec that board takes a standard 24 pin + 4pin CPU if your using a pico itx psu you may have already killed it.

m1dg3t · Jan 30, 2012

Learn somethin' new everyday! Back to my beer :toast:

O/P hope the board/PSU aint fried

I've done extensive searching and the PicoPSU is not only designed for mini-itx boards, but its compatible with numerous Intel Desktop Boards including this one.

Definitely not a problem there.

EDIT: I think I may have found the problem related to a very silly problem with cables. I'll update soon.

Just the slightest touch is enough to power it on. As stated if it's not turning on then something else is wrong.

Hope OP can update us soon. :toast:

Okay I'm an idiot. My inexperience with hardware and retail gullibility has shined through.

I'm missing a crucial cable to power the CPU. I didn't know what I was doing and relied on the product description of "powers your mini-itx motherboard without any extra cables" when really I have a motherboard that requires an extension cable to power the CPU that is sold separately.

Fingers cross I haven't destroyed it.

lol.......... :rockout:

I doubt you fried it but .. eh live and learn....

It happens to all of us at one point man, pretty sure the rig is okay. Keep us posted.

brandonwh64 · Jan 30, 2012

I did the same thing last week. I assembled my HTPC in its case and pressed the power button to get no post. I worked for about 15 minutes before I noticed no 4 pin connected LOL. Thats what I get for being in a rush

A few weeks ago I built a new rig. The thing wouldn't power on and I was under the assumption that the motherboard was DOA. Next thing I assumed was that my power supply wasn't up to the task. Turned out there was a brass standoff touching the bottom of the board.

Thankfully the board itself is perfectly fine.

Short its front-panel power switch pins with a screwdriver.

It's either broken or you are doing it wrong. For future reference you can make new threads you do not need to resurrect 4 year old ones.
