    • How did You lock it or what did you do to lock it up?
    • Did You open the BIOS menu and just turn it off under the Wireless Menu or use the Fn Lock Options?
    • How or what is preventing it from turning on again?
    • Is the BIOS corrupted or is there another reason that the default settings cannot be restored?

    So it is not possible that you do not have WiFi. It's there, but there's something stopping it from being allowed.
    PS, is the warranty valid or expired?
