Wireless adapter suddenly missing

My sister has a HP tx1000 laptop.  She said she was no longer able to see any wireless networks, so I took a look at her computer and....

The wireless adapter is not showing at all in device manager.  And there are not any unknown devices or anything either.  I have never seen a device just completely disappear from device manager.  

Has anyone ever seen anything like this before?  Is is pretty safe to assume the wireless adapter has gone bad?

Hi
You could make sure installing the adapter on another laptop.

It's actually the built in adapter that came with the laptop.  Are those usually removable?

Hi
Assuming the next:

Is it´s running on battery?
Remember the Vista has many power options, in the advanced mode you can even control the wireless device to be turned off to save energy.

Flipped the frontal switch to enable it, which I think you ´ve already done, to find out if it was disabled by mistake.

If nothing said here applies, it´s safe to say it´s gone bad.

The switch for the wireless has probably been turned off.  Look on the front edge of the machine (to the right of the microphone and headphone jacks, right next to the indicator light for the wireless).  There's a switch there.  If it's turned off, the wireless hardware will be turned off, and the operating system won't even know it's  there.

you can replace the module, if faulty; but first check the connections.

Could be cheaper to get a USB wireless adapter or a PCMCIA one.
