You may have hit a certain combination of keys on your Gateway laptop and turned on the NumLock function accidentally. The result is that the rectangle of keys from the 7 key down to the question mark key have become a number-entry keypad. Worse, Gateway manuals don't discuss this function.

Hold down the "Fn" key on the bottom row of the keyboard, and press the "NumLk" key. Type the letters UIO. If they come out as numbers, move on to the next step. Hold down the "Fn" key and press the "F11" key. Type the letters UIO. If they come out as numbers, move on to the next step. Hold down the "Fn" key and press the F11 key and "Scroll Lk" key simultaneously. Type the letters UIO. If they come out as numbers, move on to the next step. Hold down the "Fn" key and press the "F9" key. Type the letters UIO. If they come out as numbers, move on to the next step. Hold down the "Fn" key and press the "Scroll Lk" key. Type the letters UIO. They should come up as letters. If none of these help, then it's probably a keyboard malfunction and you'll need to get it repaired.

HP laptops have the ability to lock the blue special function keys on, making numerical data entry easier on laptop models that do not have the room for dedicated numerical keypads. Because the key combination to lock the function keys is so simple, however, it is easy for those who wouldn't normally use this ability to do so accidentally. When the function keys are locked, pressing certain keys will result in numbers being typed rather than letters. Unlock the function keys to alleviate this issue.

Press the "Fn" and "Num Lk" keys on the keyboard simultaneously. The "Number Lock" indicator light should turn off, indicating that the letter keys will once again type letters when pressed. This combination should work on the majority of recent HP laptops. If it does not, try one of the alternate key combinations in this article's remaining steps. Press the "Fn" and "F11" keys simultaneously, then attempt to type a letter. If the combination does not work, continue to the next step. Press the "Fn" and "Scroll Lock" keys simultaneously, then attempt to type a letter. Continue to the next step if this does not work. Press the "Fn," "Scroll Lock" and "F11" keys simultaneously.

1. Press the Fn key and while holding it down, press the F8 key momentarily to toggle muting of the speaker. An icon of the speaker appears at the bottom middle of the screen showing muting on or off.
2. After making sure the muting is off (no slash symbol on the speaker icon), press and hold Fn again.
3. With Fn pressed, press the key with the upward triangle and speaker symbol to increase volume which is shown at the bottom middle of the screen by the green lettering & vertical bars Volume ''''''''''''
4. With Fn pressed, press the key with the downward triangle and speaker symbol to decrease volume which is shown at the bottom middle of the screen by the green lettering & vertical bars Volume '''

press Fn + nmLk, it will resolve the issue.

You have turned on the numeric keys on your laptop. It is turned off/on by the following.

if you have the keyboard driver you could try uninstalling it then reinstalling it.

Sounds like you have number lock on. To turn this off you'll need to hold the function (Fn) button and press number lock. I'm not sure which is the numlock button on your model but it looks like on other models it's F11. Make sure you hold the Fn button down until you've pressed Numlock though or it won't work.

Switch NumLk off

Usually this is done by pressing Fn & F11 keys together

Or just look for the key that has NumLk on it and press it together with Fn
