|You need to search HP's site. You'll want the model number, which may be on a tag on the back of the computer somewhere.|
Alternatively, the drivers should be on a disk that came with the computer, or on the computer's hard drive in the recovery partition (depending on how they're doing things now at HP).
It matters not how straight the gate,
How charged with punishments the scroll,
I am the master of my fate;
I am the captain of my soul.
