Try the following and see if it resolves the problem...

1. Uninstall the keyboard driver.
2. Reboot the computer (yes, without reinstalling the driver yet).
3. When the computer restarts, it should reinstall the driver on its own.

If that doesn't work. try turning off the laptop, connect and external keyboard and then turn the laptop on. If the external one works fine, then there is something wrong with the physical keyboard. I would start to think something got spilled on it.
