Dismantling your laptop? *use threadlock* ;)

Recommended Posts

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

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.

Hmm, never realized they came with any sort of compound on the screws. Do they generally do this for all laptops?

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?? :)

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!

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!

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.

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.
