Nvidia display driver issued today on Lenovo support/drivers page for X1E2...Nvidia, but none for the Intel driver...

For some reason, the new NVIDIA driver is only for Windows 10 1709 version or older.

 

That's why it is not detected by Vantage, or cannot even be installed manually.

Hello joloriquelme, Would you mind also sending me the driver (.7529) if you still have them? I couldn’t find them anywhere on the internet and my x1e2 is also having the low brightness issue on .7811. Thanks !

For those who still has this problem, I recommend to you to disable Integrated (hybrid) Graphics in BIOS and let only Dedicated NVIDIA graphics enabled.

 

You will notice, aside from this issue fixed, a hugue improvement in Windows graphics performance. The battery penalty is not big considering how the notebook performance improves.

Keep in mind this advice should only be considered by people with the 4k screen; the 1080p display runs completely fine on integrated graphics. Also, the battery life gets cut roughly in half on discrete graphics only which is significant. I can probably stretch the battery life to ~9 hours with everything set to power-saving, and losing 4.5 hours isn't that appealing to me. Besides battery life, running everything on the GPU will result in the machine drawing quite a bit more power and producing more heat, something to consider if you're worried about longevity.

Thanks for the tips.


I don't care about longevity. This notebook is so bad that I will get rid of him as soon as I finish the payments for it.

Then that's a waste of money, no? Besides the poor driver quality and the lack of company response, the physical product is very much acceptable. The only real complaint I have would be regarding the back cover. The notebook is overall very good; the software Lenovo releases is what's causing most of the problems.

I still have keyboard issues.


Constantly heat and slowdowns.

 

The bottom cover and their screws has problems too.

 

And, of course, another problem could appear anytime, like this brightness problem, due to poor driver QC testing.

 

This is by far the worst computer I had in 30 years. Me and many people spent hours and hours trying to deal with issues.
