Processor board release mechanism

[Morgan Mac]

I'm having a problem with the processor board release mechanism on my 4,1 Mac Pro. You are meant to press in the tabs on either side to push out the board connected at the back. However these tabs now do nothing. You can freely slide them in and out without any resistance. To remove the board I have to grab hold of the front tab and jerk it out, as delicately as I can until it releases, and then slide it out.

I don't know what could have caused this. There may be a part missing that I took out but lost. I don't know. Can someone illuminate for me how the release mechanism is supposed to work?

Because all 5 screws are missing in your case.

All six screws securing the processor cage seems to be missing too. And couple of other screws too, from both sides of the CPU to MB socket. It might be a good idea to check all the mountings and screws.

Ahh thank you both. Yes I have the screws temporarily removed. But what difference should they make? I presume they elevate the floor of the processor board just a little bit?

The latch mechanism uses those to lock in place and push out when you flip the levers.

Ahh I see. The mystery is resolved. Thanks for the prompt responses.
