To clean the computer keyboard, use slightly damp cotton swabs. Scrub the keys and the surface around the keys.
Do not allow liquid to drip into the keyboard or you may damage the keyboard.
Using the Numeric Keypad
Your keyboard includes a numeric keypad, which is a group of keys that you can set to type numbers and mathematical symbols, such as the plus sign. A number or symbol on the left corner of each keypad key shows its numeric function.

Press <Fn>+<F11> to turn on the embedded numeric keypad. The numeric functions of the keypad are enabled and the Num Lock LED turns on. (See ”Reading the Status Indicators” on page 17 for the location of the Num Lock LED.)
While the numeric functions are enabled, you can temporarily return a key to its normal function by pressing the key and the <Fn> key. For example to type the letter m, press <Fn>+<M>, this operation displays the letter m.
To turn the numeric keypad off, press <Fn>+<F11> again. The Num Lock LED turns off.
