[citation][nom]mgilbert[/nom]And for all of you saying cigarette contamination is just dust and that you can just blow it out, you are wrong. I've seen lots of computers totaled by cigarette smoke damage. Nicotine coats the bearings in fans, causing the fans to fail. It does the same thing to the heads in DVD drives. It damages the contacts in the PCI, memory, and CPU slots, causing them to fail...The filth that builds up in a smoker's computer is much thicker and very sticky. You can blow some of it out, but the coating of nicotine and tar can't be cleaned up.[/citation]
You're not a very good tech, apparently. Probably explains why you USED to own a computer store.
Yes, it's unpleasant, but no more so than people who live in extremely dusty homes. You're being paid to do a job, so you do it. Fans fail, period. You buy them in bulk and replace them as needed, billing the customer for the part(s). You take the open computer outside and blow everything out with canned air. What doesn't come off, with canned air, you use a vacuum cleaner with a brush attachment (soft bristles only). Gunk on the contacts? You can clean this off with isopropyl alcohol and Q-tips, the same way you clean off old heat-sink compound from a CPU (talk about sticky goop!). You should know all of this.
If you don't like smokers or smoking (and I don't blame you, neither do I), then just say so. But the stuff you and techguy911 are talking about is stuff that hasn't been an issue since the early days of the PC revolution.
