Some notebook models may have more than one kind of processor over the course of their manufacturing lifetime.
In some cases, an HP Support Agent, or the instructions in a support document, may recommend that you download and install a specific updated BIOS or driver or program called a "softpaq".
Each softpaq file on the HP web site is listed with the abbreviation "SP" (for softpaq) and followed by a reference number. To download and install, or flash, the BIOS, find the specific product number on your computer and do the following steps.
Once you have downloaded and saved the latest version of the BIOS to your computer, you will need to manually install it.
The HP Support Assistant provides automatic software and BIOS updates, built-in diagnostics and troubleshooting tools for your computer.
It is the preferred method for maintaining and resolving problems on HP notebook PCs that use Windows 7 or Vista.
HP Help & Support provides easy access to software and BIOS updates for HP notebook PCs that use Windows XP.
You are strongly encouraged to download and install the latest version of HP Help & Support .
To use HP Help & Support to check for system updates: If HP Support Assistant or HP Help & Support utility is not installed, you should find which version of the BIOS and which CPU processor is installed.
If the installed BIOS version is the same as the BIOS version available on the HP web site, no additional action is needed.
