Why is the embedded numeric keypad non-responsive on the Dell Latitude 131L or Inspiron 1501? - KB Article - 323223

Using the Embedded Numeric Keypad on the Dell Latitude 131L and Inspiron 1501

The numeric keypad functions like the numeric keypad on an external keyboard (Figure 1). Each key on the keypad has multiple functions. The keypad numbers and symbols are marked in blue on the right side of the keypad keys.

By design the embedded numeric keypad does not function unless Num Lock is enabled. Unlike other Dell portable systems there is no system setup or BIOS option to change this behavior. To type a number or symbol using the keypad, enable Num Lock and press the desired number or symbol key(s) on the keypad.


The owner's manuals for the Dell Latitude 131L and Inspiron 1501 incorrectly indicate that Num Lock is enabled by pressing the <Fn> and <Num Lk> keys. To enable Num Lock, press and release the <Num Lk> key only. The light indicates that Num Lock is enabled.

To type the letters contained within the embedded numeric keypad while Num Lock is enabled, press and hold the <Fn> key and then press the desired letter(s).
