And CISNET is not telling you what to do next I'll share that I don't waste any time with such machines if it doesn't come on in 5 minutes and an OS reload is not acceptable. I carry wifi cards in my bag so I fish out either the WPNT511, WPC54G or some USB wifi stick and try that. If that works then we're done. Those that don't accept that solution have to accept the OS reload as a try then shipping the machine off to repair if the OS reload doesn't fix it.

This is not an offer to teach or find the Fn+Fkey combo or button that turns on or off your wifi internal card. You OWN your machine and must check on that as I can't be your tech support.
