Accessing Notebook Product Information

To access the updates for your notebook, you may need the following information:

■The product category is Notebook.

■The product name, product number (P/N), and serial number (S/N) are provided on the Service Tag. The information on the Service Tag is provided at Start > Help and Support > My Compaq Computer, and on the Service Tag label affixed to the bottom of the notebook.

Accessing Notebook ROM Information

To determine whether an available ROM update is a later ROM version than the ROM version currently installed on the notebook, you need to know the version of the currently installed ROM.

✎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. The BIOS also supports such notebook services as time and date.

Notebook ROM information can be displayed from within Windows or in the Setup utility.

■To display ROM information from within Windows, press the fn+esc hotkey.

In the fn+esc display, the version of the system ROM is displayed as the BIOS (basic input-output system) date. On some notebook models, the BIOS date is displayed in decimal format. To clear the display, press esc.
