Cleaning the computer case Follow all safety precautions before cleaning the computer case. To clean the computer case, follow these procedures: ● To remove light stains or dirt, use plain water with a clean, lint-free cloth or swab. ● For stronger stains, use a mild dishwashing liquid diluted with water. Rinse well by wiping it with a cloth or swab dampened with clear water. ● For stubborn stains, use isopropyl (rubbing) alcohol. No rinsing is needed because the alcohol evaporates quickly and does not leave a residue. ● After cleaning, always wipe the unit with a clean, lint-free cloth. ● Occasionally clean the air vents on the computer. Lint and other foreign matter can block the vents and limit the airflow. Cleaning the keyboard Use this information to properly clean the keyboard. Follow all safety precautions before cleaning the keyboard. To clean the tops of the keys or the keyboard body, follow the procedures described in Cleaning the computer case on page 12. When cleaning debris from under the keys, review all rules in General cleaning safety precautions on page 11 before following these procedures. CAUTION: Use safety glasses equipped with side shields before attempting to clean debris from under the keys. ● You can remove visible debris underneath or between the keys by vacuuming or shaking. ● You can use canned, pressurized air to clean debris from under the keys. Use caution because too much air pressure can dislodge lubricants applied under the wide keys. ● If you remove a key, use a specially designed key puller to prevent damage to the keys. This tool is available through many electronic supply outlets. IMPORTANT: Never remove a wide leveled key (like the space bar) from the keyboard. If these keys are improperly removed or installed, the keyboard might not function properly. ● You can clean under a key with a swab moistened with isopropyl alcohol and squeezed out. Be careful not to wipe away lubricants necessary for proper key functions. Use tweezers to remove any fibers or dirt in confined areas. Allow the parts to air dry before reassembly. Cleaning the monitor Follow all safety precautions before cleaning dirt and debris from your computer. Use this information to properly clean the monitor. ● Wipe the monitor screen with a clean cloth moistened with water or with a towelette designed for cleaning monitors. Do not use sprays or aerosols directly on the screen; the liquid can seep into the housing and damage a component. Never use solvents or flammable liquids on the monitor. ● To clean the monitor body, follow the procedures in Cleaning the computer case on page 12. 12 Chapter 3 Routine care, drive guidelines, and disassembly preparation
