Hi:
HP retired support for that model series because it is 10 or more years old.
So, finding drivers will be difficult.
First of all, there were never any W7 drivers for that model, you have to use the Vista drivers.
If you have the Vista recovery driver disk, perhaps you can get the drivers from that.
I can give you these W7 drivers so you can get connected to the internet...
You can use these W7 drivers for the quick launch buttons, wireless card, the wireless assistant, and the bluetooth.
Quick Launch Buttons
This package contains the software that enables the HP Quick Launch Buttons, which are special function keys on HP Notebooks. This software works with supported notebook models that are running a supported operating system.

HP Wireless Assistant:
This package contains the HP Wireless Assistant for the supported notebook/laptop models and operating systems. The HP Wireless Assistant is a user application that provides a way to control the enablement of individual wireless devices (such as Bluetooth, WLAN, or WWAN devices) and that shows the state of the radios for these wireless devices.

Bluetooth:
This package contains the software required to support the HP Integrated Module with Bluetooth Wireless Technology in supported notebook models running a supported operating system. The HP Integrated Module with Bluetooth Wireless Technology provides wireless connectivity to other devices from the integrated module of the supported notebooks. It also provides additional Bluetooth Profiles.
