In my quadra 650 i want to remove the PRAM-battery. And the quadra should become new RAM. But, before i can do this i must remove the power-supply. But i dont' no why. In the Service manual they describe a powersupply-screw. But they don't show what kind of screw this exactly is. Phillips? Wich size? Where is this screw exactly? Can anyone help?

And "2" is exactly the problem:

what kind of screw is it?

Where is this screw exactly? Can't find them on the rear bezel. Have anybody here a picture from the position of it. The schematic in the service manual didn't help me.

But the power supply is on somebody fixed. I can't remove it after I pry the latch (3)

However the force is use

Sorry

1 If a CD-ROM drive is

installed, squeeze its

side tabs and pull the

drive out an inch or two

to more easily reach the

power supply.

2 Remove the power

supply screw from the

rear bezel.

3 Pry the latch away from

the base of the power

supply.

4 Grasp the power supply

and firmly lift it out of

the drive mount chassis.

Note

: The firm lifting

motion disconnects the

power supply connector

from the logic board.

You can download the Service Source PDF here, it's about midway down in the right hand column:
