Solve : Ungrounded case??

1.	Solve : Ungrounded case??
Answer» Hey all, This is my first post here so bear with me. I just came across this term ungrounded case. What exactly does it mean. Does the computer restart if the computer is not grounded. What exactly is this. I'm not entirely sure what you are asking. Does you electrical service use 3 prong plugs. If your in North America the rounded third plug is the ground. Another useage, if you are working inside a computer, it's best to have a static wrist strap attached to the case, to make sure your body is at the same voltage potential as the computer. Frankly, most people just touch the case often to bleed off any static electricity build up. In general, it has very little to do with RESTARTS, but can fry components. .It might be helpful if the OP said where they came across the term and in what context (electrical safety, static damage, etc) I am referring to electrical safety QUOTE from: plckid on March 06, 2011, 05:40:12 AM I am referring to electrical safety In just about every advanced country, certainly in mine (Great BRITAIN), with any appliance, not just a computer, connected to the AC electricity supply, if there is any EXPOSED metal that can touched by a person, that metal must be "grounded" (USA) or "earthed" (Britain and British-English-speaking countries). This is to prevent a fault in the appliance making the exposed metal "live" and giving anyone who touches it a dangerous or fatal electric shock. The grounding is achieved by having a third connection at the outlet and using a three PIN plug. The third pin is connected to the case or other exposed metal, and if a fault occurs then a fuse blows or a circuit breaker trips, alerting the user to the danger and hopefully preventing an accident. If the case is not grounded, then the computer would probably still operate normally but it would be outside the regulations and also possibly dangerous.

I am referring to electrical safety

In just about every advanced country, certainly in mine (Great BRITAIN), with any appliance, not just a computer, connected to the AC electricity supply, if there is any EXPOSED metal that can touched by a person, that metal must be "grounded" (USA) or "earthed" (Britain and British-English-speaking countries). This is to prevent a fault in the appliance making the exposed metal "live" and giving anyone who touches it a dangerous or fatal electric shock. The grounding is achieved by having a third connection at the outlet and using a three PIN plug.
