Good day, so should also work with the HP Probook 650 G2.

I have installed this wifi card in an HP ENVY 17.3 inch.
The old wifi card from my HP laptop was:
Ralink RT3290 802.11B 150 Mbit / s 2.4 GHz
Slot: Mini PCI-Express

So if your HP Probook 650 G2 also has a Mini PCI-Express
for the WLan card, then it should also work.

What's more, it's more than twice as fast as the old WLAN card.
I'll see if I can find out what's built into the HP Probook 650 G2.
has built in.
