Preparing for a Software Update
If your notebook connects to a network, consult with your
network administrator before installing any software updates,
particularly a ROM update.
Accessing Notebook Product Information
To access the updates for your notebook, you might 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,
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.
» 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.
ROM information can also be displayed in the Setup utility.
The
procedure for displaying ROM information is described in
this section. For more information about using the Setup utility,
see the
“Setup Utility” section later in this chapter.
