Hi. First time on and this is a long shot I know, but…
The fan on the cooling unit of my Samsung NC10 is making a noise suggesting a dry bearing and imminent failure. How easy is it to, say, access the motor to perhaps lubricate the bearing? OK, this NC10 has been brilliant and I’ve had it for nearly two years, but I would like it to last another two. I’ve got all the screws out but it doesn’t want to play and I don’t want to break it! My usual computer wizard just had an intake of breath and scratched his head. So, any ideas would be gratefully received. Thanking you in anticipation. John
Welcome to the forum neighbour,
I think fan replacement is the general rule rather than repair. Maybe someone will have an idea though.
neighbour – Welcome to the forum
There has been some discussion on this issue before on the forum and the consensus was a small squirt of WD40 provided the fan bearings are not totally unserviceable.
Hope this helps and it’s worked for me in the past on numerous PC fans.
Thanks guys. Having a little neato notebook has its drawbacks, like you can’t climb in the back to easily replace components and I’ve never tried to pull a notebook apart. Yet! I was thinking of the WD40 too, either that or a hypodermic and some 3 in 1, given that I’m able to find the specific location of the bearing. I’ll have a bash tomorrow and get back to you. It’s bound to come up occasionally.
neighbour – The WD40 cans come with a long thin applicator delivery pipe which allows access to awkward areas. I wouldn’t think 3 in 1 oil would be suitable due to it’s higher viscosity.
Hope this helps
Ta! I removed the case screws, gently levered open the top horizontal cover about 1cm (that’s all I could get without snapping something) to get access, and gave a couple of blasts of WD40 in the direction of the bearing – well, where the noise was coming from anyway. Not very accurate – I couldn’t find a the tube, but I apparently hit the spot and It’s now running purrrrfectly. Thanks for saving me the cost of repair. I suspect that getting hold of and fitting the part myself would have been problematical, and I can’t see it being a cheap job professionally but that’s miniaturisation for you. Oh, and I reckon that if you avoid spraying the speakers, then I doubt that there’s much in the way of materials or components that could come to harm. Everything seems to be fine, anyway. Good old WD40. If it blows up I’ll let you know!
neighbour – good to hear it’s cured. I have found in the past that fairly frequent application is required to keep the bearing quiet so see how it goes.
If you find the applicator straw then it can be applied through the external fan grille obviating the need to disassemble the machine each time 🙂
Hope this helps
Thanks again jeepers, and last and by all means least, I just got some further advice from another tech-buddy: blow some compressed air through the fan area first to clean out the dust, hair and fluff so it doesn’t end up by congealing around where it shouldn’t. Oh well, a bit late, but my NC10 is working smoothly and silently even if it does smell like a machine-shop for a while.
