How to use function keys on a non-functional keyboard?

[Andrew Winds]

I have a Gateway NV55S07u. After a failed keyboard replacement, many of the keys no longer work, including all twelve F keys. The mouse trackpad works but it's locked by the function key that locks the trackpad. So my question is, how can I activate the function keys via software? Thanks.

I'm going to suggest opening the laptop and repositioning the ribbon cable for the keyboard since it's easy enough to not get it lined up just so, it may take a few tries. At least that's what I would do (if you haven't already).
