Request link for bios update and touchpad driver.

Hi:

Hp retired support for your notebook's model series since it is more than 10 years old.

Since it was never supported by HP for Windows 10, there are no W10 drivers for it.

Any BIOS update files would have been written to be run on Windows 7 or Windows 8, and I have no idea what would happen if you try and update the BIOS when running an unsupported operating system.

It could work fine, or it could permanently destroy your notebook.

BIOS version F.16 was the last update I could find for your notebook.

Here are the links to the info and exe files...update at your own risk.

There is only a Windows 7 touchpad driver for your notebook.

Thank you.

Alps Touchpad driver works well with Windows 10.

F.16 Bios driver install worked well in Windows 7.
