Oil for plastic laptop hinges

p.s.

if u look at this ebay auction of a laptop hinge

the actual hinge is a pole underneath the black part in the middle.

Grease is used on it.

the WD40 may have degraded the grease.

I seem to semember that trying to loosen the screws was difficult.

It does need fixing though, because it puts pressure on the frame, screen and surrounding plastics, causing cracks and eventually .....

THIS IS A PUBLIC SUGGESTION ANNOUNCEMENT !

-- Cheers,

John.

Silicone, as used for plumbing fittings

I'm surprised no-one has been along to tell you to stop doing unmentionable things over your laptop.!!!!!!!!! :-)

Any particular model Fujitsu? All the one's that I've seen have metal hinges buried under the plastic hinge cover.

Big mess, doesn't stay put, drips, and doesn't last. Also eats some plastics.

True. Same with most vegetable oils.

Dunno.

Silicon lube should work. However, I would use soap. That's common ordinary soap flakes or shredded Ivory brand soap bars. That's what I use for doors, hinges, screws, cd trays, and any place where I need a no-mess lube job.

Also, I would look a bit more carefully at the hinge you're attempting to lube, and see if you're not shaving plastic as it moves. The plastic chips will imbed themselves into the pivot area and eventually jam the hinge. Just cleaning out the crud might be sufficient to make the hinge work normally.

Haven't read the rest of these so there could be duplicates. I'd try some of that locksmith powdered slate; for the life of me I can't think of the "name".

Graphite...that's the stuff I was thinking of :) Worked great on my vinyl window track :)

You said not to use vegetable oils. Yet then you suggest by way of Ivory soap to use animal fat (sodium tallowate = sodium hydroxide, or caustic lye, and tallow). Because Ivory is more caustic is why it has better antimicrobial qualities. Yeah, like animal fat doesn't break down. Ivory is more caustic than, say, Dove which is more mild and is a synthethic detergent bar (synthetic surfecants and vegetable oil).

I always snickered about the "99.44% pure" slogan since they never did mention from WHAT it was pure. It was a measure against the castile soap (made from vegetable oil and less lye) against which it competed back in the 1890's regarding proclaimed impurities (maybe the fine ash used in soap-making to provide the salts) that were in the castile soap but not in Ivory.

The hard lube sticks you buy (to rub on the lube which would do nothing in the case of hinges or anywhere the lubricate needs to penetrate to interface between the working surfaces) are made from some combination of grease, wax, hardened fats (which would be more like the Ivory soap bar), glyceride, graphite or PTFE (aka Teflon), molybdenum disulfide, and a petroleum derived hydrocarbon. Obviously a soap bar or lube stick won't last long where there is any humidity. That's why using a soap bar on a kitchen drawer works well but not on drawers in the bathroom vanity. A silicone-based lube won't be permanent but it lasts longer than soap and won't build up like soap. Molybdenum disulfide (aka Moly) is a dry lubricant and would probably work better on the drawers and definitely on the hinges. Moly has an extraordinary affinity to stick to metal so it's good for hinges once you get a wetting carrier to penetrate and deposit the Moly on the mating surfaces or use a grease formula to keep it sticking in place when you re-assemble the pieces.

While I'll use a soap bar to help screw in that superlong wood screw, I'm not thereafter concerned about the lubrication qualities of the soap. It doesn't have to provide long-lasting lubrication. Just once is enough. Lasting lubrication is not what soap does. I snicker when thinking about using it on hinges, as mentioned, and then wonder why the hinge is squeaking again after a rainstorm or why the steamy bathroom vanity drawers are sticking again. Might be a no-mess lube job but it's not a good lube job.

i totally agree

washingup liquid is good on sqeaky hinges for a while, till it rusts them

Nobody wanted to mention it....

Do you have a hobby shop in your area? Esp. one that caters to Model railroaders? You can buy a Plastics Compatible Lube there.

WD-40 will not hurt a laptop hinge . Try a couple drops of sewing machine or 3-in-0ne oil . Just dont use so much where it will run all over . These oils will not hurt plastics . Your hinges are most likely metal undr the plastic .

WD-40 Main ingredient = Fish Oil!

have a smelly day! :)

Dont ever use a Water Displacer for lubricating stuff.

I would use some sort of lube like Lubriplate, Mollylube, or sylglide or White Lithium Grease

Dont use a organic based oil.

Typical programmer's bullshit.

This is extraced from the MSDS sheet for WD-40, from the WD-40 website.

More baths would take care of that BO problem of yours.

We have have tried 'WD-40', but that seems effective for only a very short time.

We are afraid to use ordinary oil as we thought it might effect the plastic. We were thinking of using olive oil, but somebody has told us that olive oil 'degrades' and goes sticky, over time.

We have got some Camellia oil that was given to us, and it's made from Camellias and it comes from Japan and is suppose not to 'degrade'. Still it's an unknown quantity to us.

Does anyone know what would be a suitable and safe lubricant in this case? Since we dont want to cause any problems with the plastic on this lap top. Grateful for any suggestions, thanks.

Give the hinges a shot of Teflon spray. Long lasting & won't hurt plastic. Shield the LCD screen just to be safe.
