The same problem with F4 key is also present in Lenovo G710 laptop. Is there also any unofficial BIOS for this model which addresses this very serious problem?
Sorry, I don't have an idea if any unofficial BIOS is available for the G710. I have got my unofficial BIOS for the G700 from Lenovo support.
I had the same problem. I just pressed the key Fn + F4 and it worked in Excel.
Hope this helps.
