Installing the CPU Voltage Regulator

The STARION Desktop PC computer's CPU requires a separate voltage regulator in order to operate
correctly.  If a new CPU is installed, a new voltage regulator might also be required.  If this is the case, the
new voltage regulator will be included in the CPU upgrade kit.

To install the voltage regulator:

1) 

Turn off the computer, disconnect external devices, ac powerand monitor power.

2) 

Unlock and remove cover.

3) 

Carefully pinch the harpoon ends on the plastic standoffs and remove the voltage regulator.

4) 

Install new voltage regulator.

 

Make sure socket on voltage regulator is aligned with pins on main logic board connector.

5) 

Align standoffs with holes in voltage regulator circuit card and carefully press down on voltage
regulator until socket is fully seated and standoffs have secured circuit card.

6) 

Replace and lock cover, connect external devices and restore power.
