Many people like the Samsung Intensity because of its slide-out QWERTY keyboard. However, one drawback to the phone for some users is that, unlike a flip phone, the numeric keypad is always exposed. When the Intensity is kept in a pocket or purse, this can result in accidental phone calls, multiple all-black pictures, and sudden activation of the voice command feature.
Luckily, you can lock the phone's keypad to keep it from engaging any functions when you're not using it. Locking the keypad is easy. Just hold down the 0 (zero) button for about two seconds, and a message will pop up telling you that the keypad has been locked. While it's locked, you won't be able to use the numeric keypad.
The standard way to unlock the phone is to press the upper right options button (the one that you would typically press to bring up your Contacts list) and then press the center OK button. (You will see prompts for both of these buttons when the phone is locked.)
However, there is also a quicker way to unlock the phone -- just slide the keyboard open. Sliding the keyboard open will unlock your numeric keypad immediately, and even when you close the keyboard the phone will remain unlocked. If you want to lock it again, you'll have to hold down the zero button to re-lock it.
You can also enable Auto Key Lock mode, in case you think you'll forget to lock your phone. With Auto Key Lock mode turned on, your phone will automatically lock itself when it's not in use and the backlight goes off. You can turn Auto Key Lock mode on or off from the Phone Settings menu.

Open the Acer laptop and turn it on. Allow the user to
complete all startup procedures before pressing any buttons on the
keyboard.
2
Locate the "Windows" button. It is located on the bottom
left-hand side of the keyboard and has a dark circle with a little
waving flag inside. Locate the "L" button as well.
3
Press both buttons at the same time. The laptop keyboard is
now unlocked. Test the computer by trying to open a file on the
computer. If the keyboard did not unlock, repeat the procedure and be
sure to press the buttons at the same time. The keyboard will unlock.
Based on your description of the problem you're experiencing, it sounds like you most likely pressed the "NUM LOCK" key. If NUM LOCK was activated before you cleaned the keyboard and was accidentally pressed during cleaning, this key press would deactivate NUM LOCK, causing the number pad to stop responding. To reverse this, simply press NUM LOCK again. The NUM LOCK button is located right above the "7" key on the number pad (see picture below).
Alternatively, since the setting determining whether NUM LOCK is activated when your computer is started is stored on your hard drive, you can try restarting the computer to revert back to an active NUM LOCK. Be sure to try this in case the first solution above does not work.
