A solution to the problem of "Lenovo" notebook "wireless network function off"

My Computer A few days ago can also connect wireless network, but, today suddenly can't search wireless network, one can not search, and then looked at the notebook wireless network led, is extinguished. At this point, I have ensured that my wireless network link is open, and the physical switch of the wireless network is open, but the wireless network is not found.

So I diagnosed the message, "Your wireless network has been turned off." So, I went online to look for the post, most useless, finally, to get inspiration, into the Lenovo official website of the drive download page (http://support1.lenovo.com.cn/lenovo/wsi/Modules/Aptitudeblank.aspx seq=1), "Drive automatic installation and repair", but also entered my host number requirements verification.

Finally, the download of Lenovo's energy management management driver, press the FN+F5, it pops up the wireless network Open section, open the wireless network.

After the installation, restart the wireless network, just fine.
