Is this happening in Windows or the BIOS where it's shutting it down due to a possible whitelist issue? At least for now, I'm going to assume the issue happens in the OS. First, I'll boot the laptop into a Linux distro such as Ubuntu to see if it's an OS or hardware fault. If the card connects, then I know it's an issue with Windows.
[quote|format=featured]***The way you know is to see if the laptop connects to a network, run lspci -nn, then look for the card; it will have a card number or Wi-Fi when you run the command on. This machine I did it on shows it without the card model, but says WiFi when you look in the Terminal window. I've run it on my 640 G9, and this is what mine does:***[br]
***NOTHING hides from lspci -nn. If the card is bad it just will not show when you do a hardware probe on the laptop.***[/quote]

If the card shows up in Linux, get your hands on an Ethernet cable and remove the device from the device manager, then reinstall it with the driver from the HP website. Once you do that, the card should work again.
