I bought a Lenovo Ideapad z580 laptop with preinstalled windows 8. After few months of use, I completely switched to Ubuntu. Everything is running fine, however I do miss the hot key for dust removal? Perhaps, the following picture in the Image will help in understanding the question.
What do I need to do get it in work? I looked for drivers on Lenovo website but didn't find anything useful. Any help would be appreciated?
