Microsoft Windows Vista SP2 Released

http://www.microsoft.com/windows/windows-vista/quick-start/service-packs.aspx

Mike_48x48 I have been working with SP2 for a while and have noticed that my system runs a whole lot smother.
They have come a long ways. I still love windows vista but I love windows 7 more. This release is a
must have. Download windows vista sp2 through windows update. For best results I would recommend
a fresh install of windows vista then do all of the system updates. There just nothing like a clean install.

Remember to backup all of your documents and files that are important to you before doing any
major update to your system.

ESD Facts

Static electricity is the accumulation of an electric charge (produced by friction) on a non-grounded object. The static charge on the surface of a non-grounded object can jump when it contacts the surface of any grounded object. This electric discharge is known as electrostatic discharge (ESD). ESD can be very destructive to a computer.
The threat of ESD begins when the fragile components (including the processor, memory, motherboard, and expansion cards) inside the computer are exposed. Damage can occur simply by placing a fingertip too close to a component inside an open computer case. ESD charges can travel through wires and into components, where the wires can explode or fuse together, causing the components to fail. There are two types of failure caused by ESD:

  • Catastrophic failures cause components to fail. The only solution for a failed component is to replace it.
  • Upset failures degrade components, leading to ongoing or intermittent problems or eventual failure. With these types of failures, it is difficult to identify the source of the intermittent problem or even know if damage has occurred.
The table below illustrates just how serious a threat ESD can be to an electrical component.
Event Charge Created (Volts)
Average computer component's operational power 3 to 5
Destroy a computer component's circuit 100 (or less, especially with low relative humidity)
Physically feel a shock 3,000
Visually detect a spark 8,000
The effects of ESD can be magnified by air temperature and humidity. Cool air is generally less humid than warm air. Therefore, ESD is more likely in the cool, dry air that is common during the winter months. Use the chart below to examine how low and high humidity levels affect ESD generation.
Activity Charge Created (Volts)
High Relative Humidity (Humid Air) Low Relative Humidity (Dry Air)
Walking over a vinyl floor 250 12,000
Moving a plastic bag 1,200 20,000
Walking across a carpet 1,500 35,000
Precautions against ESD include:
  • Use antistatic mats under the PC and on the floor.
  • Discharge yourself before touching any computer component.
  • When touching anything inside the computer, wear an antistatic wrist strap that is attached with an alligator clip to the metal PC chassis.
  • Ground both yourself and the computer to the same ground. This provides a single path for the flow of electrical potential.
  • Use static resistant materials to handle computer components.
  • Never touch the metal connectors on a circuit board.
  • Avoid dry air in the computer repair location.
  • Keep computer repair location free of materials that accumulate electric charges (for example, plastic or Styrofoam).
  • Store sensitive components in static shielded bags (usually tinted gray). Static resistant bags are not near as effective (usually tinted pink or blue). 
  • If a wrist strap is unavailable, keep your body in constant contact with the metal frame when working inside the computer.
  • Keep the relative humidity high (over 70%).
Note: Unplug the system before working on internal components. Do not rely on the power cord for an electrical ground.

Environmental Facts

It is important to ensure that equipment and hazardous chemicals are disposed of properly.

  • Consult the manufacturer's documentation for recommended solutions for equipment disposal.
  • Consult the Material Safety Data Sheet (MSDS) for information on physical data, toxicity, health effects, first aid, storage, disposal, and spill procedures for disposal of hazardous chemicals.
The following table offers suggestions for disposing of used equipment:
Component or Material Disposal Method
Alkaline batteries Regular trash. Recycling possible.
Notebook battery packs
Button batteries
Considered hazardous waste. Return to manufacturer, recycle, or contact local authorities for disposal procedures.
Monitor Contact local authorities. CRTs contain many toxic and caustic substances that are illegal to incinerate and must be encased in cement before being buried. Also, discharge before disposal (CRTs can contain high voltages.).
Power supply Contact local authorities. Discharge before disposal (contains high voltages).
PC system Contact local authorities. Recycle if possible: the typical PC contains $5 to $25 worth of precious metals.
Laser printer toner Return to manufacturer for recycling (To clean up spills, use a toner vacuum or a scoop and a damp cloth; never use a regular vacuum).
Ink-jet printer cartridges Consult with local authorities for recycling possibilities.
Cleaning solutions and solvents Consult MSDS and local authorities for handling and authorized disposal procedures.
