Q: FN Keys not working after bluetooth keyboard disconnects

Hi everybody,

I have a problem with the integrated keyboard of my MacBook Pro 13" mid-2012. My FN keys don't work anymore. When I connect my Wireless Keyboard to the Mac they work (I'm talking about the FN keys on the integrated keyboard) and when I disconnect the Wireless Keyboard they work too, but if I leave the Mac in stop for a few hours, they stop working. For some reason the volume buttons (F10, F11, F12) always work, but every other FN key doesn't work. To fix this issue I have to connect and disconnect my Wireless Keyboard. I have this issue almost every day and I usually don't have my Wireless Keyboard with me. I have unchecked the "Use all F1, F2, etc. keys as standard function keys." checkbox in System Preferences, but I still have this issue.

How can I permanently fix this?

Thanks in advance
