30 IdeaPad Z500/P500 Hardware Maintenance Manual FRU replacement notices This section presents notices related to removing and replacing parts. Read this section carefully before replacing any FRU. Screw notices Loose screws can cause a reliability problem. In the Lenovo IdeaPad computer, this problem is addressed with special nylon-coated screws that have the following characteristics: • They maintain tight connections. • They do not easily come loose, even with shock or vibration. • They are harder to tighten. • Each one should be used only once. Do the following when you service this machine: • Keep the screw kit in your tool bag. • Always use new screws. • Use a torque screwdriver if you have one. Tighten screws as follows: • Plastic to plastic Turn an additional 90° after the screw head touches the surface of the plastic part: more than 90° (Cross-section) • Logic card to plastic Turn an additional 180° after the screw head touches the surface of the logic card: more than 180° (Cross-section) • Torque driver If you have a torque screwdriver , refer to the “Torque” column for each step. • Make sure that you use the correct screws. If you have a torque screwdriver, tighten all screws firmly to the torque shown in the table. Never use a screw that you removed. Use a new one. Make sure that all screws are tightened firmly. • Ensure torque screwdrivers are calibrated correctly following country specifications.
Removing and replacing an FRU Lenovo IdeaPad Z500/P500 This section presents exploded figures with the instructions to indicate how to remove and replace the FRU. Make sure to observe the following general rules: 1. Do not attempt to service any computer unless you have been trained and certified. An untrained person runs the risk of damaging parts. 2. Before replacing any FRU, review “FRU replacement notices” on page 30. 3. Begin by removing any FRUs that have to be removed before the failing FRU. Any of such FRUs are listed at the top of the page. Remove them in the order in which they are listed. 4. Follow the correct sequence in the steps to remove the FRU, as given in the figures by the numbers in square callouts. 5. When turning a screw to replace an FRU, turn it in the direction as given by the arrow in the figure. 6. When removing the FRU, move it in the direction as given by the arrow in the figure. 7. To put the new FRU in place, reverse the removal procedures and follow any of the notes that pertain to replacement. For information about connecting and arranging internal cables, see “Locations” on page 65. 8. When replacing an FRU, use the correct screw as shown in the procedures. DANGER Before removing any FRU, turn off the computer, unplug all power cords from electrical outlets, and then disconnect any of the interconnecting cables. Attention: After replacing an FRU, do not turn on the computer until you have made sure that all screws, springs, and other small parts are in place and none are loose inside the computer. Verify this by shaking the computer gently and listening for rattling sounds. Metallic parts or metal flakes can cause electrical short circuits. Attention: The system board is sensitive to, and can be damaged by, electrostatic discharge. Before touching it, establish personal grounding by touching a ground point with one hand or using an electrostatic discharge (ESD) strap (P/N 6405959) to remove potential shock reasons. 31
