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.

@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.

hp experts, any guidance on how to enable wlan disabled (error code 702) wireless adapted disabled? wifi button remains amber. performed hard reset, reseating wlan card, update bios, reset winsock catalog but cannot enable neither wifi nor wimax. is there an option in bios to enable/disable wifi adapter? wlan card code 951144. wired connection working.
