Do not drop your computer or subject it to other mechanical shocks.• Protect your computer, battery, and hard drive from environmental hazards such as dirt,dust, food, liquids, temperature extremes, and overexposure to sunlight.• When you move your computer between environments with very different temperatureand/or humidity ranges, condensation may form on or within the computer. To avoiddamaging the computer, allow sufficient time for the moisture to evaporate before usingthe computer.NOTICE: When taking the computer from low-temperature conditions into a warmer environmentor from high-temperature conditions into a cooler environment, allow the computer to acclimate toroom temperature before turning on power.• When you disconnect a cable, pull on its connector or on its strain-relief loop, not on thecable itself. As you pull out the connector, keep it evenly aligned to avoid bending anyconnector pins. Also, before you connect a cable make sure both connectors are correctlyoriented and aligned.• Handle components with care. Hold a component such as a memory module by its edges,not its pins.• When preparing to remove a memory module from the system board or disconnecta device from the computer, turn off the computer, disconnect the AC adapter cable,remove any battery installed in the battery bay or module bay, and then wait 5 secondsbefore proceeding to help avoid possible damage to the system board.
