Technology Codes
HP does not change the name of a product every time the product’s technology changes. While this
helps ensure continuing market momentum for HP products, it complicates technology deployment
and support processes.
To help solve this problem, HP has added a technology code to the serial number of each of its
products. Since the BIOS must be matched to the notebook’s hardware, the same code is used for the
BIOS and the hardware. This manual refers to technology code differences where applicable.
The table below shows the technology codes and the changes they signify for the products. Before
downloading software or drivers or performing repairs, note the technology code for the HP notebook
model.
Note that the first two characters of the BIOS ID (for example, IC.M1.02) indicate the hardware
technology. You can also determine the BIOS ID using the BIOS configuration utility, or by pressing
Esc during the boot process when the HP logo appears.
This manual contains service information for products with the following technology code.
