Before installing the heat sink:

• If you use the existing heat sink:

  1. Remove the thermal grease on the heat sink by using an alcohol cleaning pad.

  2. Apply Lenovo proven thermal grease in a quadrilateral design on the top of the processor.

     Note

     Do not apply too much thermal grease. Too much thermal grease can result in excess grease coming in contact with and contaminating the processor socket.
