Software Updates, Restorations and Utilities
Updating Software
For optimal notebook performance and to make sure your
notebook remains compatible with changing technologies, install
the latest versions of the software provided with your notebook
as they become available.
To update notebook software:
1. Prepare for any update by identifying your notebook type,
series or family, and model.
Prepare for a ROM (read-only memory) update by identifying
the ROM version currently installed on the notebook.
2. Access the updates at the HP Web site.
3. Download and install the updates.
The notebook ROM stores the BIOS (basic input-output system).
The BIOS determines how the notebook hardware interacts with
the operating system and external devices and also supports such
notebook services as time and date.
