I can't get drivers installed after wiping and installing Windows 7 Pro back on laptop.

[stoney1964]

Hi,  I have purchased a Elitebook 8740P that had Windows 10 installed. I need Windows 7 Professional. I have installed 7 with the serial numbers under the battery for the version that came with it. The 7 I have is 32 bit.  My problem is several drivers missing. I try to put my product number D3L44UC#ABA.  HP does not acknowledge either of these numbers so I know which hardware is in my laptop so I can download the correct driver. 

It says I am missing Base System Device, BCM20702A0, Ethernet Controller, Network Controller, Universal Serial Bus (USB) Controller, Unknown Device, Unknown DEvice.  

Do you have any suggestions on what I should do?  I tried to download the SP58838 Driverpack.exe and it says didn't install correctly.  Nothing seems to work.      Thanks for any help

Hello @stoney1964

Thank you for posting in the HP Support forum. Welcome !

Good choice you have made with this Elitebook 🙂

D3L44UC is connected to 8470p, not 8740p (actually I am not aware of 8740p model).

With regards to 8470p, here are the drivers for Windows 7 >> https://support.hp.com/us-en/drivers/selfservice/hp-elitebook-8470p-notebook-pc/5212907

Visit the HP website, select your OS version, expand all and download/install them

Thanks for reply Cheryl,   I have been on the Driver page but there are several different manufacturers for different hardware and with my serial not showing I didn't know which ones were specific for my machine.   So far the ones I have tried didn't work.   I will try these you have specified and let you know.  Thanks again for help.

I'm sorry I typed that incorrectly. It is an 8470P and I have been on that driver page. There are several different options for things such as the wireless driver. With my product Id and Serial not showing I couldn't pin down which ones I needed. I have tried a couple and so far none have worked.  When I put in that Product ID it comes back not found so curious how you made that work.    Thanks

I didn't have any luck using the Product ID-D3L44UC- either. I used Elitebook 8470P which you typed correctly in product description at top of your first post. Not sure how/if @IT_WinSec got it to work.

I matched your BT driver from the BCM description which is Broadcom-which naturally indicates Broadcom Wireless also. Only one LAN driver.

Fwiw,usually looking up a model using Prouct ID leads to same drivers list. Best to audit your Device Manager to record all devices before wiping the hdd to install new OS.
