Umm.. Actually, I said a magnetic field; not necessarily mangnetism in
any real sense of the word; You haven't been around many circuit boards
I'm guessing...

Where do you think that "spritz" goes dude? It's oil. Whether you realize
it or not, it covers everything in it's path.

Do you know why the dust clings? :) Wiseass. See above, where you said
"magnetism" doesn't attract dust. A magnetic field (not necessarily,
magnetic mind you) does; that item you mentioned uses static electricity
to bring the dust to it and make it stick. I wouldn't suggest you wipe
down ram sticks with it. No, actually; I suggest you should. It would fit
right in with your repairs.

No.  It is...

Yes, but it is more the electrostatic (electric) fields that attract
debris. <w>

Dry process (xerography) photocopiers cause problems for some critical
equipment. Wet process copiers are used in these circumstances. It is
the dry carbon molecules floating about that get attracted by the E
fields.

I'm not saying that other debris isn't attracted to magnets however.

Furniture polish?

I know many lcd panels will die shortly after being exposed to furniture
polish. :)

If duster-can air "may bend the delicate fins on the fan", then the
damned fan's too delicate to be in a laptop.

It could be that I've primarily worked on either "ancient" LTs that were
built heavy-duty to start with, or "ruggedized" ToughBooks and such.

Even the standard duty LTs I've worked on held up fine with the old
"airgun", including fans.

Disclaimer:
Just because I said and do this, that doesn't mean that damage won't
occur from doing it my way....inappropriately..

You don't place the nozzle directly on top of paper labels and blast
them for minutes...

I've been using "line air" off a 70 PSI or so air-compressor for years
for cleaning all sorts of electrical, electronic, mechanical or "mixed'
devices for going-on 40 years now. I'll admit to using a water trap tho.

I did finally get a nozzle designed for "anti-static" use, it's nothing
but a metal tube filled with copper/bronze mesh  with a statground lead
attached. I could have made one 7 times over on cost/time wise, damned
thing cost $45 in '94 and took two weeks to ship it...

The airgun cleaning is done on a grounded metal bench with an exhaust
hood with a healthy suction.

Computers; be they laptops or desktops.. are just another item, nothing
special about them . I squirt the "bejejus" out of them when they come
across the bench, going into every nook and cranny, especially the fans.
I intentionally windmill the blades, both directions. This often helps
break up the gummy lube by forcing the shaft past the gunk rings. If
there's still a gunky film on the blades, I pull the fan and manually
clean it (Windex works fine here).

Same with optical and floppy drives, if the air didn't clean them out,
open them up and manually clean them.

If you've ever dealt with laptops (radios, whatever) used by fire
departments, police, military, or utility crews, you'll have a good
guess as to what finds it's way inside stuff..

I used to think the accumulated dog slobber/dander on the keyboard on K9
car MDTs was about the worst, but a cell hands-free kit installed by an
outside vendor was the worst. The idiots put the "guts box" just under
the console's cupholder. Driver was a very heavy user of RedMan chaw.
You can guess the rest.

(I'm still trying to figure out the mobile printer with a half-pound of
birdseed-like millet, not sunflower seeds-inside, driver wasn't a
pirate, not even the Seattle Seafair kind, and no birdshit found in
vehicle.)


As far as damages resulting for using the airgun?

Yes, I have lost fans, 3 in 40+ years and probably 1000+ devices with
fans. Was it *just* the airgun cleaning that killed them? Probably not.
IMHO, if the fan *was* damaged by this, it was too fragile and needed
replacement anyway!

ESD /"static"? I know that ESD exists, and I've seen the actual damage
done using a qual lab microscope to see the craters. I've yet to see a
problem caused by ESD caused by water-filtered (and "grounded") air.

My Toshiba and other cheap < $400 laptops don't have weak fan blades.

Then you probably won't have a laptop with cheaply made fan blades that bend
under a gust of compressed air -- which was my point.

I just replaced a keyboard on a new laptop this weekend (a bad "E") and
have done it in the past on various brands. I'd recommend removing the
keyboard and blowing out the insides. It's usually 2 screws and maybe a
couple of clips. You flip it out of the way, without disconnecting it,
and you can see the entire air path.

May have just blown the cpu instead of the mainboard.. not exactly sure
about the fuse... (I haven't seen an actual fuse in the laptop itself in
a very long time).. but otherwise, good advice!
