Acer 3000 when I am using word and need to type using the keys that have numbers as a Fn function the laptop only displays the fn numbers. If I use a usb keyboard it responds normally. I cannot disable the Fn function. How do I get a normal keyboard back?

what's the model? is it a laptop or just an acer monitor?

The uses for the function (f1-f12) keys varies based on which program you have open at the time. Different programs use them for different things.

However, your computer also has some default uses for these keys when combined with pressing the fn (function) key.

fn + f1 locks computer

fn + f2 changes our power use profile

fn + f3 puts the computer to sleep

fn + f4 puts the computer into hibernation mode

fn + f5 changes the display/output mode

fn + f6 decreases the screen brightness

fn + f7 increases the screen brightness

fn + f8 enables/disables wireless connections

fn + f9 enables/disables the touch pad

fn + f10 turns the cursor overlay on/off

fn + f11 turns the numeric overlay on/off

fn + f12 turns scroll lock on/off

Make sure your "num lock" key isn't enabled.

Also, make sure the fn or function key isn't stuck.

press Fn + nmLk, it will resolve the issue.

Is there a function key on the laptop? (Fn usually blue ink) is there a key with the symbol that looks like mouse pad. Hold down Fn then the mouse pad key and that should enable the mouse pad.

As you have suggested the F7 key is the one for the mouse pad, and hasn't made any difference, have you somehow corrupted the drivers. You can download them from the acer website.

when did it last work, you cloud try a system restore. Remember to press Fn + F7 again and give it a moment to enable( just in case the last time you tried it, you turned the hardware off despite it's lack of functionality)

Laptops have a Fn key in the lower left side, next to the CTRL key. Says Fn on it.
Desktops don't have a Fn key. They have special function keys along the top numbered F1 through F12.
The windows key is the one you find on desktops, and on laptops, in the same place, the key says Fn. They are not the same.

Find the key that says num lock, press the Fn key and the num lock key to turn off the number lock.

Try holding down the function key and hitting the numlock or scroll lock key, this is usually how you engage or disengage the laptops function keys on the keyboard . Most laptops have a light that will turn on and off when you do this, indicating that the funtion keys are in use.

I think for your laptop the number lock key is a second function... Try holding down the function (Fn) key and pressing the F11 key, hopefully that will turn your number lock on/off.

To toggle the embedded numberic keypad Hold down the blue Fn (function) key and press NumLk.
