HP ProBook 4320s Upgrades of missing components.

[JayKayNG]

Hi Moderator, I have an HP Probook 4320s Core i3 380M without a discreet GPU or WWAN. I am considering buying the core i7 640M. Now here is my question: Some variants of this PC also come with discreet graphics, and WWAN installed. If I am able to get these parts, can I install them on my PC? Will they work? I am looking to upgrade my PC to the MAX. I know this might be a little off-point, but please I really need advise.

Hi:

According to chapter 1 of the service manual the i7-640M processor is supported.

The graphics adapters are integral parts of the motherboard, so in order to have a notebook with the discrete graphics, you would need to replace the motherboard with one listed in chapter 3 of the service manual that comes with the discrete graphics adapter.

WWAN: You can only install the WWAN adapter listed in chapter 3 of the service manual, and it must have the HP part number on it, or it will not work.

Your notebook would also need to have the WWAN antenna wires present so you can connect them to the WWAN adapter.

Check to make sure the antenna wires are there before trying to buy the WWAN adapter.
