Re: X1 Extreme Gen 2 missing keystrokes

@alfa84 Is it possible that Lenovo provided different people different version of bios for testing?

 

Anyway I do believe that the problem is solved at least for my machine.

I've got mine back from the support centre and they have flashed the new bios on my p1 gen 2. Working perfectly now.

Two things here:

 

- Remember that most of us disabled the USB selective suspend to improve things. You have to re-enable this in order to try the system as it's should.

- I flashed the BIOS that Lenovo provided me but I didn't saw improvements.

 

BIOS: N20ET41W (1.28)

EC: N20HT33P (1.20)

 

For the people that try this, could you verify the last letter in the BIOS (W or P)?

Re: X1 Extreme Gen 2 missing keystrokes

Hi, I just found this thread (only read through about 10+ pages of the thread). I got this X1 Extreme Gen 2 as a work laptop in the end of October 2019 and pretty soon noticed the keyboard issue, but initially I wasn't sure if it was just me typing too lightly or are Lenovo keyboards just crap since I had just switched from MacBook Pro (mid-2015) which I had been using for 4 years (with or without external mac keyboard) so first I thought I would just need to get a bit more used to the different keyboard and didn't do much research on it.

Though I have noticed there was 1 or two BIOS updates installed by Lenovo Vantage and I think the issue might have gotten slightly better recently but it's still there. I think when I'm typing I don't get many missed characters too often anymore (but it's still very annoying when it happens).

But the most annoying thing that happens related to this is that the Ctrl key often isn't registered when I try to Ctrl+click on links in Chrome (Win 10) to open them in new tabs. I often do this and in this case the problem seems to occur very frequently (probably like 20-50% of the time when I'm trying to open a link in a new tab and not just trying to test for this issue). So in these cases when it doesn't register the Ctrl I need to click back button to return to previous page and then retry and usually it works on the second try.

First I thought that the left Ctrl key hardware is somehow more unreliable than the rest of the keys but after reading a bit of this thread I'm more convinced that it's actually not an issue with the actual key/switch hardware but either a problem in some control electronics or firmware/driver/software. I used to start pressing the Ctrl key with more force each time after it hadn't registered but I think now that this is unnecessary.

The problem only seems to affect the integrated keyboard. I've never had this issue when I'm typing on an external USB keyboard. At the office I've been using an external mechanical USB keyboard (Ducky Shine 4) which works perfectly.

So I guess I should contact Lenovo now to see if I could also get access to some test BIOS which could improve the situation? I live in Finland btw and this X1 Extreme Gen 2 has the Finnish/Swedish keyboard layout.

So whats the version of Bios that seems to fix the problem? Beside of that missing Strokes its the almost perfect system.

 

P.S. Removing of WIFI-Whitelist would be fine too. I dont know why Lenovo, after many years avoiding this, now starting again with this bad thing.

I will give the Firmware update another try.

I rollblack the Update flashing the official 1.28 BIOS, and then I re-flashed again the update provided by Lenovo by PM.

I will let you know what happens.

For me, after flashing the testing bios, it shows,

 

UEFI BIOS Version :   N20ET41P (1.28)

UEFI BIOS Date: 2019-11-25

 

For me the problem is solved (I believe).

 

Since yours is N20ET41W, the problem might be the BIOS version?

I really don't know.

I searched in the .zip folders and N20ET41W and N20ET41P sub-folders have exactly the same size, so I think maybe it's a region or model thing.

The important is the EC Firmware, that now is 1.20 instead of 1.19.

We will see...

@Haprog: does not solve the issue with CTRL, but you can just use the middle button (small button above the trackpad) to open links in new tabs. It works in Windows and most linux distros.
