Minus/underscore key and delete/break keys on my VGN C22gh vaio laptop are not working

The problem is that the Fn Hotkey Utility breaks when XP SP2 or some other patch goes on. You can fix this by using the Vaio Recovery Wizard. Click on it, then Proceed With System Recovery, Custom Recovery, Application Recovery. Select HotKey Utility then Repair. It takes a reboot and works after that.

This is a skill you will get good at with a Vaio as it seems that every driver update or patch from Microsoft will break something.
I hope this helps!

Hope it works!!!!!!!!

The minus key (-) to the right of the zero key (0) at the top of yuor keyboard, is what you're looking for. If you hold down the Shift key and then press that Minus key you will create an underscore (_).

I really hope this helps, but if it does not, please post your laptop model name so I can better answer your question!

Try these drivers:

My Vaio model is VGN-FS840 and after I formatted by laptop, my function key is not working, what shall I do to make it run? Can I download the driver? is it available in websites?

Hi,
To enable the Fn keys functionality, you need to install the "Vaio Event Service" and "Sony Utility Series"
They are available to download as part of a package from the Sony website. Here is the link:

Did you spill something on it? (the most common cause of this issue).

try cleaning it with dry cloth, compressed can of air, etc......NO WATER/CHEMICALS.

if that don't work, take it to a shop, or if it's still under warranty, get it repaired/replaced directly from SONY.

take the key off and see if the key is on right

I guess all you can do is try dry the water by tipping the laptop upside down (Keyboard face down) and also use a hairdryer or something hot to try and dry it. Dont overheat it!!!
