Hi:
I have zipped up and attached below, the driver you need for that device.
You will have to manually install the driver as follows...
Download and unzip the file to its folder.
Do not do anything with the files in the folder.
Go to the device manager. Click on the unknown ACPI\HPIC000C device needing the driver.
Click on the driver tab. Click on Update driver.
Select the Browse my computer for driver software option, and browse to the unzipped driver folder.
Make sure the Include subfolders box is checked, and the driver will install.
Then restart the PC.
