4REAL Posted April 30, 2013 Share Posted April 30, 2013 Just stripping down my freshly arrived second hand Y500 (2 months old) and QUITE a few of the screws have been loose. So if anyone else is planning on doing a complete stripdown then i would DEFO recommend reassembly using a Thread Locking Compound (or any decent Nutlock medium strength) to avoid things coming loose in the future.. i was surprised what a measly amount of compound was on the screw threads! not even enough to go once around any thread... hence why already coming loose after 2 months Quote Link to comment Share on other sites More sharing options...
Bluekross Posted May 15, 2013 Share Posted May 15, 2013 Yeah I noticed this too, even just the screws on the bottom cover. Maybe 2 out of 8 had compound on them the first time I took them out. Quote Link to comment Share on other sites More sharing options...
Uberperson Posted May 16, 2013 Share Posted May 16, 2013 Hmm, never realized they came with any sort of compound on the screws. Do they generally do this for all laptops? Quote Link to comment Share on other sites More sharing options...
Brian Peterson Posted May 16, 2013 Share Posted May 16, 2013 Thanks for the tip!! Can we purchase extra screws from somewhere?? I have lost screws in the past. Why not be proactive about it right?? Quote Link to comment Share on other sites More sharing options...
Riona Posted May 23, 2013 Share Posted May 23, 2013 I got extra screws from a laptop repair shop! My Y500 didn't come with a mSata and I needed a very small screw to lock down my mSata upgrade. The guy at the laptop repair shop was nice to give me a buch of screws in various sizes without charge! Thanks for the tip!! Can we purchase extra screws from somewhere??

rplacd Posted May 26, 2013 Share Posted May 26, 2013 I suspect the previous user of the OP's laptop's been fiddling with disassembly as well - but we can't all forget we're getting enthusiast's niche laptops! Quote Link to comment Share on other sites More sharing options...
dl123 Posted May 30, 2013 Share Posted May 30, 2013 For what it's worth, in the Lenovo machines I've disassembled, I've noticed the small amount of threadlock but it seems to hold great. Quote Link to comment Share on other sites More sharing options...
rplacd Posted May 31, 2013 Share Posted May 31, 2013 I've just found a service manual: Lenovo haven't been keeping to themselves any particularly interesting revelations (not if you're in the know, at least; the fact that the CPU's locked in with only a ZIF mechanism just blows my mind), but it does have a interesting bit of closure:Screw notices Loose screws can cause a reliability problem. In the Lenovo computer, this problem is addressed with special nylon-coated screws that have the following characteristics:• They maintain tight connections.• They do not easily come loose, even with shock or vibration.• They are harder to tighten.• Each one should be used only once.

shizknight Posted June 16, 2013 Share Posted June 16, 2013 I'm glad you posted this. I've had mine apart and I've already noticed one of the screws was loose. Quote Link to comment Share on other sites More sharing options...
