I've tried the fn and f7, uninstalling and reinstalling the drivers for this and it's not done anything to solve the issue.

Try this to see if this has something to with your issue.

Perform power drain. 
1. unplug power source
2. flip the computer upside down and look for a tiny pinhole with battery symbol next to it
3. grab paper clip and insert it into this pinhole.
4. Now press and hold the paper clip for 30-40 sec
5. turn on the computer and check if any changes.. do let us know if the issue is resolved or not
