Iâll say it more clearly this time. I was not referencing the Intel silicon bug with my previous post, but a hypothetical situation. I was only trying to use this hypothetical situation to prove that these âcorner casesâ are very important for some people.
Whilst that is clearly true it doesnât follow that any such case let alone, all as :-
" Hardware known to not work on framework V1, must be fixed " which is the subject of this topic
I wonder what you mean. I have the V1(Gen 11) and the hinge is fine, it doesnât need a fix. Maybe you have a faulty hinge which official support can help you with.
That image you posted is a bit weird. The hinge is absolutely âstrongâ enough it isnât going to break. There is/was an issue that some had a low threshold and the screen would not support itâs own weight when over a certain angel, but I said support will fix that,
The new stiffer hinge means there may not be the option to open with one hand, so that furthers the option on how stiff it may be.
The so called cons on your image, are irrelevant to the this topic. That there are no other screen options is not a âHardware known not to workâ and there never was any indication that alternate screens would be available to âupgradeâ to.
likewise, i have a 11th gen and no problems with the hinge, it seems like itâs been more of a personal preference of people. unless, of course, itâs actually broken.
What I mean, is that notebookcheck who is reviewing many laptops, is saying the hinge seems to be à problème compared to other products in its pro class.
This website is pretty serious and delivers acurate testing. I would prefer thembsaying the build seems even stronger than a thinkpadâŚthan the hinge are bad⌠It just coroborates the many complains hereâŚ
Again we are talkingn of a laptop in its class⌠If I buy a 200⏠lap I can imagine it breaking sooner.
Hinge on pro laptop like thinkpads is one of the part the most tested. So yes it s a real concern even for the current professionnal laptop providers
Think there are multiple ways to look at this hinge issue:
There was a quality escape issue, with a particular batch IIRC. Has there been QC improvement changes made going forward to minimize the chance of this from happening? AND is it actually improving the outcome (this needs actual stats)? i.e. Fixing hardware outcome by process change. (Handling in assembly stage)
Framework Support also changed the bar / criteria for hinge replacement. Has this criteria been updated into the QC process change.
In either case, the âfixâ is not on the spec / design of the hardware, but fix of process (QC step) and QC barâŚwhich will align the hardware that lands in customersâ hands with whatâs in design spec.
Also, note that itâs not clear to the public how this QC step is carried out to validate against this QC bar. On paper, the spec is on the hinge itself. However, the warranty replacement with Framework Support is against the assembled outcome behaviour of the laptop as a whole. So, at the factory, are they checking against the hinge itself, or the laptop as a whole?
@Iann_C I think you raises valid points/concerns. The current hinges will not work with a future touchscreen upgrade and for some they are too loose and clearly for others not.
@Amoun@marco the 3.3 kg hinges can be 2.8 kg or 3.8 kg while in spec. have you considered you might have ones that are closer to 3.8 kg rather than it just being a case of personal preferences? Have you measures the force needed to move your screens?
So true. I would think that 2.8kg vs 3.8kg would have some perceivable differences in user experience.
Edit / Add: Question - Why isnât there a tighter tolerance? Cost, initial funding. But weâre now into 2nd yearâŚcanât this be improved with a tighter tolerance?
There are no reports of the hinge breaking, I have said this before.
You are reading a biased report, as all are. The issue with the hinges has been explained, if you get a âsoftâ one you can return the whole laptop or get a replacement hinge etc.
@Usernames Iâm aware of the range and of course I may have one at 3.8Kg.
Yes I have measured the force required and it takes 0.5Kg to lift the lid, then it gets stiffer to a max of 0.8Kg. So with two hinges thatâs between 1 and 1.6Kg. Maybe my scales are a bit of but not by more than 10%.
The whole laptop weights around 1.3Kg. If you hold it by the lid the bottom will drop slowly, so if all weight were in the main part then the hinges almost holds 1.3Kg which means each hinge only needs to hold 0.65Kg, much the same as my weighing measurements.
Well thereâs a difference between a âcooling offâ period and a faulty hinge.
The new V2 comes with the same hinge, so clearly the general idea is that they work fine.
The 4Kg does not allow one hand opening, for those that donât want it.
The laptop is sold as a âone handâ opener, so no, the 4Kg hinge is not made as you suggest.
If there was a common failure in the 3.3Kg then no doubt they would now sell with the 4K but they donât, itâs a preference. and unlike a touch screen is easy to produce etc.
For the lid, which weighs about 300g max it would only require hinges with a combined âstiffnessâ of that i.e. 0.15Kg each. So if they were even at the low end of 2.8K or 1.4Kg each then I donât see the problem.
This didnât take the centre of mass away from the pivot point into consideration. Specifically horizontal distance. And this changes as the hinge is at different angle while going through the rotation.
I wasnât able validate my ânominal hinge forceâ either but like you I measure the force needed to move the screen. Assuming you also used the top of the lid as the measuring point here are my values:
To open 350g to 90 degrees, onwards this drops to 150g then to 50g after ~135 degrees.
To close from flat 375g from 90 degrees it starts at 300g dropping to 75g.
To qualify for a replacement hinge you (originally) need to have it unable to support itself from a 155 degree angle, this margin has been widened but the indication is the screen still needs to fall under itâs own weight.
My screen does not fall under itsât own weight but will move quite easily, is my hinge a 2.8kg and yours a 3.8kg?I have no idea but if that is the case the wide tolerances make the 3.3kg unsuitable.
Because it has been implied the level required to get a replacement from support is falling under itâs own weight I mention the 4.0kg hinge as an option to those who donât meet that requirement and want a more stiff hinge overall.
If I only move the screen by the front edge there is no horizontal difference and anyway how would the horizontal distance change by degree of opening? ??
In the second scenario (âmove the screen by the front edgeâ)âŚthe vector of the torque you provide to pivot the screen changes. (For example, if thereâs no friction on the feet, you wouldnât been able to turn that past 90 degrees.
In the first scenario, the vector of gravity doesnât change.
Above I understood 500g peaking at 800g force to move the lid my lid peaks at half that so I donât think they are similar at all.
Iâm not ok with such a low force required to push it over. Every time I pick it up is falls a bit, shake my leg is falls, slowing down on the train hold on tight! It makes for a very non premium feel and is not very practical either unless you use the laptop as a desktop.
