Updating programs and drivers
HP recommends that you update your programs and drivers on a regular basis to the latest versions.
Updates can resolve issues and bring new features and options to your computer. Technology is
always changing, and updating programs and drivers allows your computer to run the latest
technology available. For example, older graphics components might not work well with the most
recent gaming software. Without the latest driver, you would not be getting the most out of your
equipment.
Go to the HP website to download the latest versions of HP programs and drivers. For U.S. support,
go to http://www.hp.com/go/contactHP. For worldwide support, go to
us/en/wwcontact_us.html. In addition, register to receive automatic update notifications when they
become available.
Cleaning your computer
Cleaning your computer and external devices helps keep them in good working condition. If you don't
clean your computer, dust and dirt particles can build up.
