6. Depress the power supply latch 1 . Slide the power supply assembly toward
the front of the computer and remove it from the chassis.
7. Ensure that the new power supply is the correct replacement. Some power
supplies automatically sense the voltage, some power supplies are voltage
specific, and some power supplies have a voltage-selection switch. If there is a
voltage-selection switch, use a ballpoint pen to slide the switch, if necessary.
Note: For models that have a switch:
v If the voltage supply range is 100–127 V AC, set the switch to 115 V.
v If the voltage supply range is 200–240 V AC, set the switch to 230 V.
8. Install the new power supply into the chassis so that the screw holes in the
power supply align with those in the chassis.
Note: Use only the screws provided by Lenovo.
9. Install and tighten the five screws at the rear of the chassis to secure the
power supply. Reconnect all power supply cables to the drives, adapter cards,
and the system board. Make sure to reconnect the power cable to the graphics
cards that require an additional cable.
