Oil for plastic laptop hinges

The hinges on our Fujitsu laptop screen appear to be 'all' plastic and they get very 'difficult to move' making the screen difficult to fold up and down.

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.

I suggest you contact Fujitsu's tech support to discuss this problem.

That could be the cause of your problems. Firstly WD40 isn't really a lubricant and secondly it can attack some plastics which can lead to plastic hinges gettign stiffer as the WD-40 glues the faces together. It's a bit of a lottery depending on the plastic used in the hinges.

You would be better off using either silicon grease or a dry lubricant. Avoid anythign containing graphite because it conducts electricity and shouldn't be used on electrical or electronic items. Farnell sell a dry lubricant which should be better for this application:

Dry graphite lock lubricant, maybe ? A tint squirt of wax furniture polish ?

The hinges on LTs are not plastic but have a plastic covering over the steel hinges. Loosening the will result in the screen lid not staying in the position thats required of the user.

If you must loosen them then do it the proper way,get it serviced. If its out of warrenty then try and find out how to remove the plastic covering of hinges,normally this can be done without having to dismantle the whole casing?

Silicone lubricant should do what you want. I bought a large aerosol from Halfords, but that was a few years ago.

Are you sure you want to be spraying graphite around near a laptop?

Well, I take your point on its potential conductivity, but I would consider it highly unlikely that sufficient could actually get inside to anywhere 'electrical' enough to cause a problem, when treating an external hinge. Obviously, a degree of common sense would have to be applied, but perhaps I am assuming too much, as WD40 has already been tried ... :-) I notice that you have carefully removed the question mark that I had after the word "lubricant" which changes its context rather, from the 'possibility suggestion' intended, to a statement, which certainly wasn't intended.

Screen appear to move' makinges on our fujitsu laptop screen difficult to move' making they get very 'difficult to move' making the hinges on our fujitsu laptop screen appear to fold up and they get very 'difficult to move' makinges on our fujitsu laptop screen appear to fold up and the hinges on our fujitsu laptop.

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

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

Unknown quantity to 'degrade'. Still it's made'. Still it comes from camellia oil that was given to us, and is suppose not to us, and is suppose not to us, and it come camellias given to 'degrade from camellia oil that was an an and is suppose not some camellia oil that was given to us, and it come camellias an unknown quantity to us. We have got to 'degrade'.

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

Many such things are 'lubricated' on assembly with a damping fluid - a bit like the spindles on controls - to give that "stirring treacle" feel (a wonderful expression - found on this group)

A typical long chain molecule compound is this one:

this can make the assembly feel very sloppy. Alternatively it may have some sort of spring loaded expanding spindle to give some braking effect.

If you can get the hinge covers of, you may find a few screws holding the hinge-proper in place.

You could try loosening these, or even dismantling the hinge and cleaning it. They will be metal parts,

You may find a manual for the laptop on the Fujitsu website.

p.s.

if u look at this ebay auction of a laptop hinge

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 .....
