My Lenovo z580 shows nothing when i tried to turn on my Wi-Fi by pressing Fn+F5. Any solution or alternative to turn on wifi?

Looked at the specs on your laptop and you have the wireless card included. I assume you have a router set up already or you have access to another wireless network. Follow these steps to access it from your laptop:

1. Go to START
2. select MY COMPUTER
3. Once in the new window, click MY NETWORK PLACES under the "OTHER PLACES" section
4. select the VIEW NETWORK CONNECTIONS link under the NETWORK TASKS section
5. RIGHT CLICK on your wireless network connection and choose PROPERTIES
6. click the WIRELESS NETWORKS tab.
7. make sure the "USER WINDOWS TO CONFIGURE MY WIRELESS NETWORK SETTINGS" box is checked
8. Click OK and close the window
9. RIGHT CLICK on your wireless network connection (the name of it) and choose REPAIR
10. if windows detects the wireless connection, you should see a bubble near the task bar
11. in order to begin using the wireless connection, open your web browser then enter your username and password (if required)

Here are two drivers I managed to find for you, they're on lenovo's website fyi.

1) If your wireless adapter is Intel

2) and if it is BroadCom

Hope this helps, stay spicy and happy lappying! :)

Try restoring your computer to earlier time using System Restore,
on Explorer click Help menu - Help and Support Center and select Undo changes to your computer using System Restore.

SOURCE: switch on the wireless device first?

PLease locate the slider switch at the edge of your laptop. there should be a small slider switch for your wireless. Try to look at the sides or at the front of your keyboard.
