Laptop keyboard not working properly after windows 10 update

The Windows 10 Upgrade probably fails to recognise your laptop keyboard because you had the external keyboard plugged in during the upgrade. The general advice from MS is to disconnect all external hardware when performing the upgrade.

Try Scan for Hardware Changes to see if that picks up your Laptop's keyboard (Right-Click on the Start Menu Button to use the 'old' Control Panel functions such as Device Manager). There may also be a Driver compatibility issue that needs resolving, if
so it would probably be best to check if your Laptop Manufacturer has released any updated Windows 10 Drivers.

 

Laptop keyboard not working properly after windows 10 update

I have just updated my medion laptop to windows 10 while doing the update I had a usb keyboard pugged in during the update.

Windows 10 is working fine, but the inbuilt keyboard is not. Being a laptop keyboard some of the buttons double up as a numerical keyboard when numb lock is turned on.

Now on the keyboard if t turn on numb lock the the numbers type fine. eg press letter 'L' number 3 appears. if I turn numb lock off and type those letters nothing happens. type letter L nothing appears on screen

The only way I can type the letters is to hold the fn key down while typing. To turn on numb lock I have to press fn and numb lock button.

any ideas how to fix this
