Y740 15" Capslock light, and keyboard lighting profile issues

2020-06-05, 0:20 AM

I spent 3 hours with chat support today and they asked me to make this thread so that the right people (software engineers) at Lenovo get this information.

 

The first issue is the capslock light, which turns on when booting the machine, restarting the machine, or waking the machine up from sleep when using the Lenovo Vantage software (and bios) feature that swaps the F-keys to become the secondary functions (like screen brightness and sound volume). I have attached an image of the option from the vantage software which causes this behavior.

 

The second issue is the hot key fn + spacebar which is supposed to swap between custom iQue lighting profiles. This hotkey only swaps between default pre-programmed by Lenovo profile while iQue is off, but when iQue is on then the hotkey stops working. This prevents the user from quickly swapping between custom profiles which is advertised as a feature (second attached image). 

 

Neither of these can be fixed without some sort of bios/firmware update by one of the primary software engineers at Lenovo.

Also an engineer who reads this and is actually going to work on this, please also change the primary default lighting profile to pale blue as it was in keyboard firmware 1310. In firmware 1311 the default is rainbow swirl which is very disruptive, and instead of having that as the primary default profile, it could easily be the secondary default profile (when using the fn + spacebar function if no custom profiles have been created). For this reason many users including myself have gone back to 1310 (this doesn't related to the first and second issue I mentioned. both firmwares have the same primary problems).

 

 

This might not seem serious to others, but I consider this a very serious set of issues, that needs to be resolved and that support cannot resolve without the real experts creating software updates. 

Thank you to any engineers who take on this project!

Another detail I picked up about the capslock light issue from a 9 month old reddit post was that the issue was first spotted when a user upgraded to bios version 1.06. Our current version is 1.08. So presumably one could look at the change in the code from 1.05 to 1.06 and find the mistake causing this bug.

Every time I swap between the two keyboard top row function options in the image I posted, the capslock key light turns on (for special function option) and off (for f1-12 option). This is definitely the issue and requires a software engineer.

Also discovered that logging in and out (also with different user) causes the capslock light to activate when the function option I talked about before is on. Seems some windows driver when activated causes this issue, although I still feel the real root cause of this issue comes from the bios or keyboard firmware.

Still waiting for an official response from a Lenovo engineer for this. Thank you.

I need an expert to notice this problem and update the bios or windows drivers accordingly. Anyone?

Thank you for making this post. It seems that there are no Lenovo engineers listening at all.

 

I actually love this computer, every little detail about it, EXCEPT the horrible keyboard lighting integration. 

 

I truly wish it was not even present. Just give me a basic keyboard backlight. I'm not a fan of this RGB nonsense anyway. 

Let me give you a little perspective, though. I have no fix for the Caps lock. It seems to be a symptom of setting the Fn row to not require the press of the Fn button for their special task. I've gotten over that one. It is what it is. 

However, the rainbow thing was unacceptable to me. By going through forums I realized that what I needed to do was roll back the driver of the "Lenovo Keyboard Lighting Firmware update Tool for 15inch".

https://forums.lenovo.com/t5/Gaming-Laptops/Vantage-installed-the-wrong-driver-for-Y740-17inch-keyboard/td-p/4464481

It's been a while since I did it, but read through this thread and use one of the 15 inch firmwares indicated in it. When I rolled it back, the rainbow went away, and I've just been avoiding updating the Keyboard firmware tool every time it tries to get me to do it. I honestly forgot which one I selected but when I rolled it back, it stopped giving me the rainbow. 

 

The problem is not the iCue, you can update that one safely, it's LENOVO's keyboard firmware that is the problem. 

 

EDIT: Actually, I think this is the one that I used. 15inch: https://download.lenovo.com/consumer/mobiles/kyb15fw02u/kyb15fw02u.exe

 

It doesn't fix the caps lock and it doesn't fix the Fn+Space, but it does enable you to stop the spiral Rainbow in the iCue software.
