- 1Uninterruptible power supplyAn online device that is constantly providing battery power to the computer and being recharged by the wall outlet.
- 2Alkaline batteriesRecycle alkaline batteries if possible. Otherwise, dispose of alkaline batteries as your local laws require. For example, in some states, you can throw them in the regular trash. In California, they are considered hazardous waste and are supposed to go with the household hazardous waste collection for special recycling.
- 3Button batteriesThese are considered hazardous waste because they contain mercuric oxide, lithium, silver oxide, or zinc-air. Return them to the manufacturer, recycle them, or contact local authorities for disposal procedures.
- 4Nickel metal hydride (NiMH) batteriesRecycle NiMH batteries. Lithium batteries are considered a non-hazardous waste.
- 5CRT monitorContact local authorities for recycling CRTs. They contain many toxic and caustic substances that are illegal to incinerate. Discharge CRTs before disposal, as they can contain high voltages.
- 6PC systemRecycle, give it away, or resell old PC systems. A typical PC contains $5 to $25 worth of precious metals. Remember to clean the hard drive before disposing of the machine.
- 7Power supplyContact local authorities for regulations. Recycle power supplies if possible. Discharge before disposal, as they contain high voltages.
- 8Laser printer toner cartridgesReturn cartriges to the manufacturer for recycling (to clean up spills, use a toner vacuum or a scoop and a damp cloth; never use a regular vacuum).
- 9Inkjet printer cartridgesRecycle these cartridges. You can return the cartridges to the manufacturer for recycling or recycle them yourself.
- 10Cleaning solutions and solventsConsult the MSDS, a licensed disposal organization, or local authorities for handling and authorized disposal procedures for solutions and solvents.
- 11TemperatureThe hotter computer equipment runs, the faster it ages and degrades. And if a system is hot enough, it is possible for hardware components to be destroyed.
Internal fans and cooling systems can typically maintain the internal temperature of your computers.
External temperatures of offices, server rooms, and data centers should be monitored.
The general guideline is to try to keep the temperature at 68-degrees Fahrenheit, but cooler temperatures can be even better especially in server rooms and data centers where there are a lot of systems close together. - 12HumidityComputer systems do not function well with too much or too little humidity. Computers are designed to operate within a humidity range, so you need to monitor the humidity within your organization, especially in your server rooms and data centers. Too much humidity can result in condensation. Too little humidity can result in electrostatic discharges. The drier the air, the more easily static sparks can jump and damage components. The recommended humidity level is usually between 40 and 60%.
- 13VentilationGood ventilation can go a long way in maintaining temperature, humidity, and airflow. PCs and laptops should be used in an area where there is plenty of space for air to flow in and out. Server rooms and data centers often use hot and cold aisles that are designed to ensure that hot air is removed, and cool air is pushed into the room.
- 14Computer vacuumUsed to remove small bits of dust and dirt. Be careful using near small components.
- 15Damp clothA damp cloth with mild soap and water can be used to clean the outside of a computer and monitor. Be sure to unplug any electronic device before cleaning with water.
- 16Denatured isopropyl alcoholDenatured alcohol can be used to clean metal contacts (like those found on expansion cards).
- 17Compressed airUse compressed air to blow small particles of dust and dirt from inside your device.
