My immediate problem is that I am trying to disconnect a PSU from a PC.

I've got most of the disconnections done

The big motherboard connector is not cooperating.

I've attached a picture.

From websites, I've read that there is some sort of locking mechanism involved.

There is a button/tab/whatever to push.

I'm not seeing it.

Would someone be kind enough to point it out?

 

BTW my long term problem is that my main PC quit working.

When I push the power button, I hear some start up sounds followed by silence.

It doesn't even beep at me.

 

Edit: If there is a better place to ask, that would be useful information.

There should be a locking tab on the opposite side of the connector to that seen in the image. It'll be on the wire side connector, not the PCB connector. Try googling Molex Mini Fit Jr. - pretty sure the connector is from that series/ family of connectors.

Middle of the connector, on the side photo don't show. It's quite tight usually, I often press the motherboard with another hand while pull the cable off to avoid damage.

E: actually it's not full width connector so it's not quite at the middle http://img.tomshardware.com/us/2006/12/14/how-to-build-a-pc-part-3/atx.jpg

Thanks.  Found it.  Thought I'd looked there before.

Those ribbon cables are really nasty for navigation.

 

Next question:

What do I do with the lock?

Push down, pull up, push sideways, twist clockwise (counter-clockwise on Tuesdays)?

 

In addition to being geometrically challenged, this one opens the case of his PC with fear and dread.

Its pretty-much dead state is what induced me to do it this time.

What do I do with the lock?

Look at the photo posted above by Jonis.

 

You pinch the top part towards the wires.

It is a see-saw.

This pulls the both part, with a tooth, out from under the overhanging tab.

 

Then pull the entire connector vertically, up out of the PC board 1/2 of the connector.

 

Take a Photo with your cell phone of the connector as is, before you mess with it.

 

That way, if there is any question about how it should be installed when you go to put it all back together you have a photo to review.

Edit:

Never mind...

Follow Jonis's instructions, as it depends upon the locking mechanism.

Push it "down" like towards the connector, from the upper part of the clip, which then let's the clip come over the locking edge, when pulling the cable off.

Thanks.  It's out.
