Preventing lid glass cover (not screen!) cracking from getting worse

My Lenovo Yoga 730 laptop (convertible) has recently developed some cracks in the lower left corner of the screen.

At this point, it is purely cosmetic. The cracked area is outside the actual display area, it's just part of the lid. But I'm concerned that this crack might expand and make using the screen impossible. Is there anything I can and should do, to prevent this from getting worse?

I kinda like the laptop a lot and don't want to replace it.
I've added lots of RAM, replaced the battery (although I'll have to do that again now), and the fingerprint reader stopped working pretty early on (but that's just Lenovo's $@$*!& software support). Other than that, I'm quite happy with this laptop, and wouldn't mind using it a few more years instead of producing more trash!

That's why I'm proactively hoping to get some advice on how to 'preserve' the current state.

FYI: the missing little piece left of the hinge fell out months before the screen issue. I still have it, but have never remounted (-glued) it. That might have contributed to the screen damage — or maybe it's entirely unrelated, no idea. Just wanted to mention this in case it might be an essential component of the solution here.

@hheimbuerger if you just want to "sort of" repair it without replacing anything, I'd suggest anchoring the cracks and fragments with some Glass Epoxy. When it comes to adhesive etc., I am kind of a Loctite proponent. Something like this 349 Impruv Light Cure Adhesive should work for you. Of course, any other glass adhesive or even two-part epoxy, should work as well.

If and when you apply any adhesive, place your laptop in a position where you minimize the possibility of any of that getting into the actual LCD panel.

Now, every time you open or close the lid, there might be additional tension on the glass, and it might lead to complete failure. Consider replacing it eventually. Let us know the complete model number for your Lenovo so we could try and help you with that as well.

Awesome, great tips, I'll research those materials! I'm a newbie when it comes to this kind of hardware stuff.

As for replacing it, it's a Yoga730-15IKB (FullHD, touch/pen screen). It seems like there's already a guide here: Lenovo YOGA 730-15IKB Screen Replacement

The part seems fairly difficult to source (found it on AliExpress, but not locally in Germany). It is quite expensive and, of course, non-trivial to install. Not sure if I want to tackle that, or maybe that might be the point at which I'd consider buying a new device instead... Need to think about that. I'll try patching it up first. 😉

@hheimbuerger yes, I support that wholeheartedly :-). Patching it is the way to go. That way you can continue to use your computer without spending the money on replacing something that can still get nursed along for a while. I do hope it all works out for you!
