Q12:. Can the Fn+F5 key combination be used on all ThinkPad computers to enable or disable the wireless features?
A:You can use that key combination to enable or disable the wireless features only if ThinkPad Hotkey Features Version 1.03.0391 or later is installed on your computer. If it is installed, the wireless icon is printed on the F5 key.
I have what could be a wireless icon on my F5 key, so presumably I've also got that software installed, but the Fn+F5 still doesn't do anything. This is a brandnew laptop, purchased only 2 months ago.
As far as I can tell, this IBM redbook: http://www.redbooks.ibm.com/redbooks/pdfs/sg247045.pdf says that Fn+F5 has to be specifically enabled using the IBM ThinkVantage stuff. So perhaps it is an FAA requirement that laptops have such a switch, but it doesn't have to do anything? /Per Jessen, Zürich
