some keys not working on lenovo g570

[Lizzy656]

I have a Lenovo G570 laptop and some of the keys in the middle row don't seem to be working at all. THE A-S-D-F-J-K-L colon/semi colon aren't working...all the rest work fine. The on screen keyboard works fine as well. Any ideas?

Might go to device manager and check for a driver update, if none, uninstall the driver then shut down and restart - it should reinstall the driver. Might also try cleaning the laptop keyboard:
