Your laptop will most likely look different than this, but many manufacturers use some variation of using keys on the right side of the keyboard as a numeric keypad with Num Lock. Launch the Search charm by pressing < windows > key + C.When you push them, they register as the symbol highlit in the red circle. Under Boot Options, tick Safe Boot and hit OK. The other would be by booting in Safe Mode.

When you press the Num Lock key (seen here highlit in a red rectangle), 15 of the keys switch modes into a simulated numeric keypad. One, you can physically inspect your keyboard for obvious defects. Here is an example a keyboard made by Acer for a Windows 10 laptop. Instead of changing cursor keys into numbers, it converts a section of the QWERTY letters on the keyboard into a virtual numeric keypad. Most laptops don’t have dedicated numeric keypads, so Num Lock works differently on them. Blocking the ambient light sensor may turn on the keyboard backlight. NOTE: Ambient light intensity is measured by the ambient light sensor. What’s Different About Num Lock on a Laptop? Click Start, All Programs, and VAIO Control Center. With Num Lock turned off, the keypad registers as cursor keys (like up and down arrow) and some editing keys (such as Home and Insert). OEMs such as HP, Asus, and Toshiba don’t offer settings to adjust keyboard brightness. Microsoft Surface users can use Alt + F2 to increase the keyboard brightness and Alt + F1 to decrease the brightness.


With Num Lock turned on, the numeric keypad on a desktop PC works like an adding machine keypad with numbers and symbols (such as *, /, and +) that represent mathematical operations. To open it, right-click on the Boot Camp icon in the system tray and then click Boot Camp Control Panel option.
