Re: Yoga x1 3rd gen keyboard backlight flickering

Thanks for the information Horgh. It is unfortunate to hear. It means it indeed can be a serious issue and not only driver related. Really not a fan of going through hardware repair at this moment, but let's see how it goes.

To be honest it is disappointing indeed that on day 1 this happens and furthermore i have the docking station coil whine issue as well. With such price range it is hard to accept such quality failures.

On the other hand I understand it just got released, mistakes happen and really hope Lenovo takes prompt action with solving those issues.

Good point as well Smiley Happy

Is there anyone using recent bios and NOT having this issue? If yes, can you please share the exact model you are having?
Mine is 20LES01W00
I have reverted to 1.07 and experiment whether the problem persists there as well.

Thanks!

I've got a X1Y3 model 20LD0017US and I've been updating BIOS vesions as they've been appearing, currently on 1.11. I have auto keyboard backlight enabled in Vantage, and I haven't seen any flickering.

Re: Yoga x1 3rd gen keyboard backlight flickering

There's no reason to think it had anything to do with a specific model. The keyboard is the same across all, as is the BIOS. FWIW I didn't have this problem immediately after updating to 1.11, it appeared a bit later, but once it appeared it's never gone away.

Re: Yoga x1 3rd gen keyboard backlight flickering

@jefferai, there might be a relation. You never know Smiley Happy

@joeixgig's version is the vPro 8650 version. Mine is the 8550 non-vPro.

It also did not appear immediately on my unit, but then if there is no 'pattern' whatsoever and in some units just works and others not regardless of the model, it goes more and more into the direction of faulty hardware and low quality checks.

Re: Yoga x1 3rd gen keyboard backlight flickering

The model of my X1Y3 is 20LD001CUS. I've had auto brightness turned on for the keyboard since I got it a week ago and haven't seen any issues with flicking of the backlight.

I've got the 20LD..US version 8650 16GB Vpro and I've not had the keyboard flickering issue. That's 3 20LD..US versions so far that don't have it, at least 2 w/the 8650, I think.

Re: Yoga x1 3rd gen keyboard backlight flickering

I have the 20LD and experience flickering, though I upgraded to BIOS 1.11 right away and can't say if it would have been there on 1.10.

Re: Yoga x1 3rd gen keyboard backlight flickering

I'm on 1.11 and haven't had this specific issue on current nor previous version.

 

Prior posters mention sleep/wake and fn. Could be lenovo's ambient light detection + keyboard dimming breaks upon sleep/wake? My prior laptop had several issues related sleep/wake and was a 2-1 device. The sum of my experience w/that one was that whatever functionality and req's related to 2-1 form factors seemed to create a lot of driver/etc issues compared to a trad. laptop form. Was (is) surprising considering most tablets and laptops are stable and what's being added from a user standpoint seems to be just a few that give the 2-1's any of their 'extra' utility. When i say it had several issues, I mean it had them and persistently over the first full two years of it's release, and only calmed down after about 2 yrs. I'm REALLY hoping this is not a repeat of THAT experience, considering a main reason I bout this one was that It was 3 iterations into it's particular model/series, not including all the non-thinkpad 2-1's lenovo produced until this one. I understand bugs and design changes and possibly different part sku's can create new problems, but at this point- at Gen 3 (min), those (and any and all, really) issue should be quite predictable. Of course maybe that's unreasonable, but it doesn't feel so.
