[ramai]

i want to put in a  PCI Express half-length mini card and the specs say it is there I just cannot find it.  Is there any diagram identifying it or can someone point it out to me?  thanks

Hi:

Below is the link to the product specs for your PC:

HP ENVY 700-074 Desktop PC Product Specifications | HP® Customer Support

The PCI Express half-length mini card slot is already occupied by your PC's HMC Wi-Fi adapter.

When you look at the 'expansion options' motherboard specifications you have to assume that you are looking at a bare motherboard with nothing installed.

Thanks.  I see the reltek wifi adapter.  My problem is that the computer no longer recognizes the wifi adapter.  It says not found.  Looks like i can unscrew the old wifi card, carefully take out the cables, noting which side they were in.  then pull out the oldd one.  Then I can put in the new one, screw it down and reattach the cables.  After one of the recent windows upgrades it stopped working.  I understand that is a problem for the reltek wifi adapters that many are no longer recognized after recent windows 10 upgrades

You're very welcome.

Yes, that is a very common problem with the Ralink Wi-Fi adapters and W10.

They only worked reliably for the first couple of W10 builds.

Now that you found the Ralink Wi-Fi adapter, if there are two Wi-Fi antenna wires connected to it, you can replace the card with this model for an upgrade.

Intel Dual Band Wireless-AC 7260 802.11 ac 2x2 Wi-Fi + BT 4.0    HP Part # 710661-001

You can find this model card on eBay.

Search by the HP part number, not the model of the Wi-Fi adapter.
