Re: [CGUYS] Cleaning the Dust out of a PC
Disagree. Collecting air and dispersing air are two different things. One is an entropic process and the other increases order. Put simply, static generators have a source and a collector. Bring air to a central point makes the vacuum the collector. Blowing air involves no collector. I don't know if the vacuum stories are apochryphal but I don't think blowing air and sucking it in are equivalent.

Re: [CGUYS] Cleaning the Dust out of a PC
I pulled out a CD drive cleaning disc and ran it on my burner. Sure enough, some of that chased dust had managed to work its way inside to coat the lens on the burner. Caveat! So it is better to suck than to blow and better to be wet than to be dry and necessary keep everything grounded and above all: stay out of helicopters!

Re: [CGUYS] Cleaning the Dust out of a PC
OK, I've been reading this thread with amusement and decided to add my $0.01 from experience. I have a can of compressed air and decided to dust my machine a while back. I was very careful to use short bursts of air to avoid condensation. I finished by using a ever so slightly moist rag to wipe some surfaces inside and out and carefully closed the case and went back to work. A few days later, I needed to burn a disc but my drive wouldn't recognize the blank so I opened the case to try to see what might be loose, etc. Seeing nothing, it finally hit me what probably happened. I pulled out a CD drive cleaning disc and ran it on my burner. Sure enough, some of that chased dust had managed to work its way inside to coat the lens on the burner. Caveat! YMMV But if both the vacuum cleaner and the computer are grounded I expect that static discharge will not happen. -- So it goes - Kurt Vonnegut, Jr. (1922-2007) * == QUICK LIST-COMMAND REFERENCE - Put the following commands in == * == the body of an email send 'em to: [EMAIL PROTECTED] == * Join the list: SUBSCRIBE COMPUTERGUYS-L Your Name * Too much mail?

Re: [CGUYS] Cleaning the Dust out of a PC (was Unable to boot PC )
A good vacuum cleaner will be grounded and the hoses are plastic and should not be conductors of static. I bought an attachment kit a long time ago that I can add to the end of the Vacuum hose that has small attachments it use in Computers and have used them extensively to clean out the dust bunnies and other accumulated matter that gets into a PC that sits on the floor.

Re: [CGUYS] Cleaning the Dust out of a PC
I heard that vacuuming was bad because of static. Probably not, Tom, Why do you say that it is unlikely that the vacuum could create static? You have made an unsupported assertion. Please explain. If you know why moving air with a vacuum cleaner would cause static, please let us know. Here are three reasons: 1 a copier tech told me vacuuming causes static 2 Vacuum cleaners are sold with anti-static hoses, because there is a static problem from vacuuming. See: Wet and dry vacuum cleaner, anti-static power vacuum cleaner http://www.kaiserkraft.co.uk/equipment/wet_and_dry-51.html 3 Look to John's original message, go to the Langa letter and find this link http://www.informationweek.com/hardware/showArticle.jhtml?articleID=60403472 pgno=6queryText= Here Mr. Langa says, It's generally best not to use a vacuum cleaner inside a very dirty PC, though: Vacuuming heavy dust accumulations can generate a static charge and may damage your PC's electronics. Blowing dust with compressed air is messier, but carries a lower risk of static discharge inside the case. Please give a reason for you position.

Re: [CGUYS] Cleaning the Dust out of a PC
I asked around a bit, and the best answer was this from an engineer co-worker: There is no significant difference between blowing air and sucking air. However, people are used to vacuuming by *touching* the thing being vacuumed with the hose. People generally don't touch the hose blowing air to anything. It is undoubtedly touching or getting very close that would allow any static build-up to arc.

Blowing compressed gas is no more likely to generate static than sucking with a motor drive. If moving air caused static then the cooling fans that are in the computer would be creating static too. This is another of those urban legend things. * == QUICK LIST-COMMAND REFERENCE - Put the following commands in == * == the body of an email send 'em to: [EMAIL PROTECTED] == * Join the list: SUBSCRIBE COMPUTERGUYS-L Your Name * Too much mail?

Re: [CGUYS] Cleaning the Dust out of a PC
Every time I vacuum my carpet the plastic hose becomes charged with static electricity. Cat and dog hair cling to it and sometimes small scraps of paper. Now it could be the friction of the cleaning wand on the carpet fiber, Precisely what is happening. This is the classical method of creating static electricity. but anyone who doubts that plain old air movement can lead to static electricity buildup must have never seen a thunderstorm. Where do you think the lightning comes from, Thor's hammer? The theories all involve stuff that happens with ice or water molecules, not air molecules. It's so easy to avoid the possibility of damaging expensive electronics by blowing the dust out instead of sucking it, why take the risk? Because blowing makes an unnecessary mess. Are you going to disconnect all the fans in your computer? * == QUICK LIST-COMMAND REFERENCE - Put the following commands in == * == the body of an email send 'em to: [EMAIL PROTECTED] == * Join the list: SUBSCRIBE COMPUTERGUYS-L Your Name * Too much mail?
