Press the num lock key but if it is on f11 or something hold the fn key and press it
Simple. Just press the numlock key of the laptop and it will automatically be turned off. Hope this helps. <><
There should be a button labelled numlock, push this and it will toggle number pad on and off.
unplug it
undo numlock
Don't laptops use the numlock key? Because I think that you have to press numlock, then 3 to get a number. Just remember to turn off numlock when you're done with numbers (there shoud be a little light somewhere)
The external display has nothing to do with it :). You have numlock turned on, turn it off by either pressing function (fn) + numlock or just the numlock key, it depends on try way your computers configured. Usually if your function key is the same colour as the numlock text, you need to do the first key sequence, if not, just try the other :)
You are better off buying what you need off the dell website.
on your mouse pad on the very right slide your finger down it and it should scroll down
One reason the Fn key may appear stuck is if you recently plugged a full-size keyboard into your laptop and pressed the NumLock key. This key activates the Fn key on the laptop. To return the Fn key to its original state, plug in the keyboard and disengage the NumLock key. Remove the keyboard and test out any of the Fn assigned keys. They should return to normal working status. If it doesn't however, you may require further troubleshooting. You can find out if its the numlock by holding the fn key to type normally. if it types normally then and oposite when released then that's the problem. you can turn it off by holding the fn key and presing either the blue "num <arrow down>" or the blue numlock key. (both are numlock just look different on some laptops.
You could try changing it from BIOS settings, my dell inspiron laptop has an option there. There is also a setting on windows mobility center (press windows logo button + x).
turn it off, then turn it ON... idiot
Just push the cap lock key again to turn it off.
