That's a little extreme and never the case from what I've seen, and I've worked exclusively on HP's for my job at school.
Check in device manager and make sure the wireless didn't get disabled in there. When it's disabled there, the switch does nothing, you can still install drivers for it, and BIOS still detects it. With the DV line in HP's not all of the BIOS versions will show the install status of a wireless card so I wouldn't count on that being a deciding factor here. However, if it's not appearing at all in device manager and it is enabled in BIOS, then odds are the card itself is dead. Depending on the specific model card inside your laptop a replacement can cost between $60 and $120.
