Sometimes electrical components needs to have all power sources removed and reintroduced to work properly.  Try performing a hard reset first, if it doesn't work then we'll move to the next step.

To Perform A Hard Reset

• Shut down the computer by going to the Start menu and selecting shut down. (If you have no display, hold the power button down for  5 seconds); (if the computer doesn't power on, move to the next step)
• Disconnect the AC Adapter from the notebook.
• Remove the battery from the bottom of the notebook.  There will be a switch/button to eject the battery.
• Wait at least 1 minute with all power sources disconnected.
• Re-insert the battery and reconnect the AC Adapter and then attempt to power on the notebook.

thks  Kalt. did hard reset several times. reseat wireless, updated bios to f 27,  as well. but it doesn't work. even perform system recovery but wifi button remains amber. have tried to install wlan latest drivers but it fails. despite resetting also the winsock catalog successfully, it doesn't seems to have solved the probblem.

What shows up in the Device Manager for the wireless adapter? Is it even listed? Does it show an error?

Have you had the notebook serviced or parts replaced that might have caused this to happen?

@AT this point, I would reset the BIOS to defaults.  If that doesn't work, give HP Technical Support a call @ 1-800-474-6836 (US) and see if they can ship you a replacement WiFi adapter or offer some sort of service/fix for it.
