I cannot turn on the wireless card on my Lenovo Thinkpad 410s running Windows 7. It simply stopped working. I tested with boot from disk and it works...not a hardware issue. I have checked BIOS, reloaded drivers, etc.

I am out of ideas. Has anyone else had this problem? Has anyone solved the problem?

Does it have some kind of wireless switch utility software or some FN key combination you have to press? It's normally Fn+F5 on thinkpads. – Oct 27 '12 at 11:26

Check the hardware switch on the right side (next to the Thinkpad mark on the palm rest), see picture below:

You can also run the self test programs that are included in ThinkVantage (press the blue button above F5). The test points can and example of the result are shown below:

pressing Fn+F5 in Windows brought up a control panel which allowed me to power it on my R400.
