Re: E485 strangely unresponsive keyboard

Anyone have problem with the 3 buttons on top of the trackpad, especially the left button does not seems to repond to click all the time. This had irriated and stressed me greatly, when a click is not registering and you have to click another 1 or 2 times even. 

 

Not to mention the BSOD while watching YouTube videos. It happened anytime.

Re: E485 strangely unresponsive keyboard

I'm having the same issue with several Y11e's that we have. Specifically the Type 20E7 versions.  What I've found is that you can correct this issue in Windows 10 by making the following registry key edit:

 

HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Enum\USB\VID_048D&PID_8380\5&2bae313a&0&8
 
In this registry key, the ConfigFlags REG_DWORD binary value needs to be set to 1
 
This fixes the keyboard delay issue, but it also disables the auto-rotate function on the touch screen. Apparently there is a hardware conflict between the keyboard and the accelerometer that detects the touch screen position.

Re: E485 strangely unresponsive keyboard

I wrote some code to test the severity of the issue for the E485/A485, but it also works for any other keyboard or Thinkpad. You can see a description of it at https://www.reddit.com/r/thinkpad/comments/9ivh0u/thinkpad_keyboards_measurement_of_polling_lag_and/

Re: E485 strangely unresponsive keyboard

Yes, I have been ranting about the three button problem and the fact that none of the official trackpoint nav drivers work. 

 

Also the video driver issue can be mostly fixed with 1803 windows update but it does not address the horrendous throttling it experiences, or the half as advertised battery life.

Re: E485 strangely unresponsive keyboard

All, I have an A475 with the exact same keyboard issues that started this thread. I haven't found a thread anywhere else that mentioned the a series but I'm hoping someone from Lenovo can tell me if there is a similar update for my A475. Having to really slow down my typing when using this laptop. 

 

Thanks for any help that you can offer.

Re: E485 strangely unresponsive keyboard

OK, so no reply at all? Not the only thread I've posted in but no respsones here. I've only had this machine for a few months but I guesss I'll have to dump it. Too bad cause I like everything else about it.

Re: E485 strangely unresponsive keyboard

You'd think that after a 50% profit margin they'd care about their customers and the quality of their thinkpads at the VERY LEAST. But NO. NEVER.

Re: E485 strangely unresponsive keyboard

Andy,

This issue also effects the A475 models. Is there a bios update for this model that can be shared?

Re: E485 strangely unresponsive keyboard

They'll make you replace the keyboard anyway and won't listen. I'm honestly surprised they fixed it in the E485 because they've completely ignored fixing any of the ACPI issues (which they fixed in the A485). It's been really disappointing from Lenovo and I'm upset that I had bought a stack of Lenovo laptops (not these) for work just before I received my E485.

Re: E485 strangely unresponsive keyboard

Hi Xepter, yeah - this is what I'm worried about. There is a whole load of feedback from people, but listening seems difficult 

 

It looks like its only AMD laptops that are impacted... i.e. models with a "xx5" (their AMD numbering convention).

 

Whilst I have just bought this A475 (end of line) and got a 3 year warranty, it looks as htough I'll need to spend time and effort until its fixed. This could be frustrating.
