i got a Probook 640 G1 from my workplace for free. I want to upgrade a few things, nothing special. But on the right corner are two empty slots, i think there should be the wlan nic, because there are cables for it.
I think the user documentation from that notebook i found on the HP Homepage is pure **bleep**, because there is not really any thing about the needed hardware to read.
Anyone knows which NIC i need for which of the 2 Slots? I think one is for SIM and the other for WLan, but i am not sure.
