LEGION Y740 17ICHg ISSUE

2019-06-28, 19:32 PM

I recently updated the device to the BIOS version AVCN19WWV 1.09.But the ICUE program for keyboard lights shows that I have the 15-inch model...The lights do not turn on properly and some of them can not turn off...How can I reinstall the 17-inch BIOS ???OR return to the original version AVCN16WWV 1.06

Solved! See the solution

Same issue here. Since the last BIOS update, half of the keys don't light no more. This is a big problem, since it makes it almost impossible to use the keyboard. I hope they find a fix to this rotten bios VERY quickly.

I am also having the same problem, but the other way around. I have the 15 inch model and it shows as a 17 inch. Are you sure the BIOS is the problem? Mine says that it also installed a keyboard firmware 1311 which might causes the problem.

Same issue with the Y740-15ICHg. Got pushed a bios update and multiple keyboard firmware updates, and now random keys don't light up.

I'm having the same exact issue. I have the 17 inch model. I noticed the Lenovo Vantage Updater showed both the 17inch and 15inch Lenovo keyboard backlight updater tools being downloaded and for some reason it only installed the 15inch updater which left my keyboard just as everyone here has described. What we need is access to the Lenovo Keyboard Backlight Update Tool for our respective models, as it is not available under the Driver download page for these machines, even though the Regular BIOS Firmware is available. For everyone wondering, the Lenovo Backlight Update Tool is separate from the BIOS Firmware Update Tool and it is the reason the keyboard is now messed up.

I have a similar issue, but instead of iCue recognizing the wrong model, it says it can't detect a device at all. Same computer. Already tried to go through support, and while the guy was very patient and tried to help me as best as he could, it still didn't do anything after two full hours of troubleshooting. I don't know what to do anymore. I see that there's a keyboard update, but that still can't detect a device, so I can't install the update. Updated my BIOS, despite Lenovo Vantage still suggesting the same update.

 

I'm at a loss. If anyone can help, please do.
