Display System Information (fn+esc)
The fn+esc hotkey displays information about system hardware
components and software version numbers.
» To clear the display, press esc.
In the fn+esc display, the version of the system BIOS (basic
input-output system) is displayed as the BIOS date. On some
notebook models, the BIOS date is displayed in decimal format.
The BIOS date is sometimes called the system ROM version
number. For information about updating the system ROM, refer
to the “Software Updates” section.
Keypads
You can use the embedded numeric keypad in the notebook
keyboard or connect an optional external numeric keypad. The
embedded numeric keypad cannot be used while an external
keypad is connected to the notebook.
