I have a client that brought their HP Pavilion dv7 in because they couldn’t get it to view any available wireless networks (the wifi seems to be off). I tried for a while, but couldn’t get the wireless light (on the F12 key) to turn blue (it was orange). Here is what I figured out:
Click on the triangle in the system tray (near the clock), right-click on the HP Connection Manager icon (if you hover it will tell you wifi and LAN status), make sure it is not in Airplane mode and choose to turn the Wi-fi On.
After I turned it on, I wasn’t able to get it back to the strange disabled state, so please share any more insights below.
