Understanding your computer’s BIOS settings is crucial if you frequently find Num Lock turning off unexpectedly. By accessing BIOS, you can determine how your computer manages the Num Lock state during startup:
-
Starting Your BIOS: To access the BIOS, reboot your computer and press a specific key during the initial boot-up process (commonly Del, F2, or Esc, depending on your system).
-
Finding Num Lock Settings: Within the BIOS menu, look for the “Integrated Peripherals” or “Keyboard” option. Depending on your motherboard, there may be an option labeled “Num Lock on Boot” or something similar.
-
Adjusting Preferences: If this setting is present, you can change it to ensure Num Lock remains active on startup.
This adjustment is particularly useful for users who rely heavily on the numeric keypad.
Factors Influencing Num Lock Behavior
