Lenovo Y50-70-- Keyboard stops working during windows boot

Hello all! I write to you today from an external keyboard placed on top of my laptop, because my keyboard stopped working last night, first by losing an e key, than a r key, and then, when I restarted the laptop, thinking it would be solved by doing so, the entire keyboard would not work past a certain point in windows boot. It does work in BIOS and I can even watch caps lock light up and go off and turn the backlight on and off.

Things to note

1) The last software change was 2 days before this happened. It was an update to Windows 10. which is my OS.

2) My system restore points will not work due to an issue with AppXstaging (not sure if solvable).

3)There are two HID compliant devices in my keyboard section on device manager. and a ps2 compatabile keyboard (which is the one I'm typing on right now)

 4) I emphasize that the keyboard DOES WORK in BIOS and during boot, up until the point I can see my windows icon, and Cortana.

 

Things I've tried

1) sfc scannow comes back with there being issues it couldn't fix as well as ones it fixed

2) chkdsk enjoyed scanning my computer for 5 hours last night and fixing some issues

3) I do have an event viewer full of errors regarding filter manager and storage, but nothing I could see with the keyboard.

4) Black majik

5) I have uninstalled so many devices from device manager to let them install that my mouse hands hurt. Perhaps the place in the boot process it is freezing is when the driver reinstalls?

6) The problem still occurs in SAFE mode.

 

Anyone have any ideas? :/ I'd really rather not send this in for warranty, but in the 7 months I've had this computer, I've had so many issues, it's astounding.

 

 

UPDATE: it does actually seem to be hardware related, and the freeze doesn't happen until I hit the following keys on my keyboard:

QWERT

ASDF

 

(and this is why it works in BIOS-- no need to hit these buttons until windows boots and I try to open noTEpAD...)

 

How do I go about getting this fixed, as it is under warranty?

Re: Lenovo Y50-70-- Keyboard stops working during windows boot

Hi Rose,

 

Welcome to Lenovo Forums.

 

About the keyboard issue I am not sure. I have heard that there is another Patch update for Win 10 that has been released, you may want to check and install that in Windows Update functionality.

 

Method 1:

Try to remove keyboard device via device manager (right click my computer > manage > device management > keyboards > find your keyboard > right click and select remove > then restart your computer)

 

Method 2:

If the keyboard is working fine on the login screen and then suddenly stops functioning when you get to the desktop / metro screen then the problem might be with the Filter Keys - similar to this thread.

Try to turn off Filter Keys by going to Control Panel > Ease of Access > Ease of Access Center > Make the keyboard easier to use > uncheck Turn on Filter Keys then hit apply.

If same problem, you may want to consider doing a clean windows.

 

Method 3:

If it doesn't work, you may need to replace the keyboard, contact Lenovo service centres and ask for replacement for free if you have valid warranty.

 

Let us know how you get on.

Regards,

Shashi

It sounds like you're having what happened when my keyboard started failing, but it's taking it longer. Mine was under warranty so they replaced the keyboard. You'll probably either have to do that or what I did temporarily-- start using an external keyboard. It could be other issues, so make sure to troubleshoot it throughly, though, being that you didn't include much info.

 

Best of luck to you!
