So, I have this Acer Aspire m5 481 pt model (W8.1 64bits). After some updates the Fn key on the keyboard seems to doesn't work, as an example: fn+up key means volume up right? Well, it doesn't do anything, same with the rest of the short keys working with Fn key.
I have tried a lot of posible solutions like download launch manager and re installed drivers.
I want to know if is there any possible solution or should I just recover the entire system?
I don't know what to do, I hope someone could help me step by step if has had the same problem.
