Provided the ground at the PP is intact, and in older houses that is by no means guaranteed, one particular powerpoint type often has no earthing contact at all after 10-15 years, the socket is spread too much to make contact. Static is never a problem until it strikes your system, then you sit up and take notice. I regularly measure static charges as part of my work and you'd be amazed at how many volts you can generate just walking across a floor. It gets up to 10's of thousands, or more. There are only two types of person involved in the static argument, those who have been stung by static discharge, and those who haven't ye.........oh shlt!! Cheers Billy 8-{) :eek: |

| 838685 | 2009-12-11 12:47:00 | Bottom line is: serious about anti static, then DONT WEAR SYNTHETIC CLOTHING. OK, that about 100% of us breaking one of the more important anti-static procedures right there. This is near the top of the list(from the semi manufacturers) I had to learn way back in the day. Standard geek dress: Cotton t-shirt and jeans and leather soled shoes.... oh and go commando, very hard to find real cotton jocks these days. |

Hmmm lets run through those -- Cotton t-shirt --- Check:thumbs: Leather soled Shoes --- Check :thumbs: Jeans --check and go commando --- be careful :eek: May get "more" than static feeling :D :lol: Then you would see some real jumping about .

| 838688 | 2009-12-11 22:59:00 | I always use a strap, its a simple precaution and takes seconds. Must have gone through about 6 of them over the years. | DeSade (984) | ||
| 838689 | 2009-12-12 04:37:00 | I always use a anti static wrist band. They're really cheap. Much cheaper than replacing a part :S | Mister (15201) | ||
| 838690 | 2009-12-12 06:37:00 | Hi John May I bring a little enlightment to this question . As you will see, both sides of this debate are kinda right and kinda wrong . All modern computers use a combination of Cmos and Mosfet techknowledgly . Most, not all, have built in anti-static protection . Goto HERE ( . fairchildsemi . com/an/AN/AN-248 . pdf" target="_blank">www . fairchildsemi . com) for an example and explaination of basic in-built protection . This is the saviour of many intergrated circuits, computers and electronic equipment . I remember in the eighties, I had just started work with a company that serviced electronic taxi meters . These were right up to date and used Cmos thoughout . Out comes my anti-static mat and grounded wrist-band . The head Tech came over and asked me what I was doing with all "that crap"!! I proceeded to give him a lesson in anti-static procedures . Much to his credit, he listened intently to me, something I'm sure he already knew . At this point he picks up a brand new Cmos chip, rubs a pen on his sleeve and holds the pen to the pins on the IC!! :groan: Now test it he says, as he throws it in my direction as he walks away . I tested that chip to death trying to find fault but there was nothing wrong with it!! That instance had a profound effect and remained in my head for all these years . I've even repeated the experiment!! If you think this is a very good reason not to use anti-static procedures, then you are wrong . Call me old if yah must but it gives me a good sleep at night knowing I haven't buggered some poor prick's computer!! Using proper anti-static will do no harm, not doing them might . BURNZEE |

| 838691 | 2009-12-12 07:30:00 | I often get zapped by my car if I am wearing a synthetic pull over. Same must apply to a computer. Low air humidity will also produce more static. | mzee (3324) | ||
| 838692 | 2009-12-12 11:39:00 | Hi Mzee Low air humidity will also produce more static. Just a quick note to correct this belief. Air humidity by itself does not generate static. Only way is by rubbing two dis-similar surfaces together. As Fairchild Semiconductor puts it ... The ambient relative humidity, of course, has a great effect on the amount of static charge developed, as moisture tends to provide a leakage path to ground and helps reduce the static charge accumulation.
