Have you ever experienced a laptop keyboard not working suddenly? Maybe this is like what I experienced, I accidentally disabled my laptop keyboard, so my laptop keyboard didn't work.
Maybe you accidentally left it and how do you reactivate it?
Make sure the keyboard driver is installed and functioning properly
Click start> control panel> hardware and sound> device manager> Open the keyboard, see if it is yellow and has an exclamation mark?
If so, then the cause is your wrong keyboard driver.
Right click on the problematic driver> Update driver software> search automatically, Windows will look for a suitable driver for your laptop, you can also search manually if you are sure you know which is suitable for your laptop.
Make sure you don't lock or disable the ease of access center
Open the ease of access center (in the control panel> ease of access)
Click "Make the keyboard esier to use" make sure you don't check any of the settings.
Also open the "set up filter key" make sure to uncheck everything.
Still not working? Change the temporary driver
This is what I experienced, at first I was surprised because I did not find problems that occur in drivers and kicks on EOAC. Finally I tried this method and succeeded.
Enter the device manager> Right-click on the working driver (if I'm PS / 2 Standard)> Update driver software> Change with any driver (manual search) then click next next and Windows will restart automatically> After restarting, enter the device manager and right click on the installed keyboard driver again, Update driver software> search automatically, then Windows will look for the right driver for your laptop.
