Lenovo B50-80 Keyboard stops working

Hey Community

I encountered a rather strange problem yesterday when my wife turned on her Lenovo we bought a month ago. It is possible to enter the PIN at the Win10 startup page, but as soon as we enter Windows, no(!) key works. Neither Keypad nor Keyboard.

We tried:

- accessing the Bios, which works and in which the Keyboard works normally

- deleting the Keyboard PS/2 Driver from the Hardware Setting Menue, which results in a re-installation of this driver but still the error remains

- plugging in a USB keyboard which interestingly receives power and the volume buttons works, but here the same, the keys do not function (and this one also does not work at the windows pin screen).

- waited until Win10 installed all updates, even the anniversary update, but still nothing changed (was my last hope. D'oh!).

 

Right now I'm quite lost and don't see why things do not work. Really need some help here...

Thank you in advance

 

BTW: It's a  Lenovo B50-80 80EW0521GE as far as I understand it.

Re: Lenovo B50-80 Keyboard stops working

Hi SJ1982 , 

 

Welcome to the Community Forums. 

 

On what we have:

Keyboard works in BIOS and in Windows log-in

Fails the same using external keyboard with evident power.

 

Would using onscreen keyboard work ? How was it on safe mode ?

How was it if you create another account?

 

This would isolate driver issue from a user account / system corruption.

A system restore (jumping back to previous working date) may help.

 

Update us how things go. 

 

Regards

Re: Lenovo B50-80 Keyboard stops working

Hey friendly Spidey,

 

the onscreen keyboard (I assume you mean the thing at the login screen with the half-circle button, with which I can type in my passwords using the mouse?) worked fine. Couldn't find that same device after going into Win10.

 

The Keyboard did not work in safe mode either (nor did the USB Logitech keyboard). I did not create another account, but yesterday I used the system restore. This worked as there was no "set point of system restoration" but a whole push-back to delivery condition.


So now the keyboard works again and as far as I can see it updated all win10 updates normally without interfering with the keyboard - but I lost all the data during that process as I thought it was a system restoration to a former date. Smiley Sad

 

Anyway, thanks for you assistance. As far as I can tell, something went wrong with an update and the system restoration looked like the only thing that helped.

Hi SJ1982 , 

 

From a fresh start , it would be best that you activate the system restore feature (to jump back to previous date) to avoid a full factory reset that clears up your data (click on highlight for guide).  

 

Then have at least a control on the automatic windows update as drivers are being affected by follow this guide.

 

These two things would prevent same driver issues happening again. 

 

Anyways, you have our community at anytime you need assistance and also for sharing your thoughts among fellow forum members.

 

Always good to hear all is well.

 

Regards
