I have a Dell Laptop Latitude E6500 How do I unlock my number lock key, it is located above my F4 key with same symbol

Hi Tiffany,
Found this after googling .....
Here is how you enable the number lock feature:
1) While booting up press F2 repeatedly
2) After the Dell logo appears, you will be diverted to a Settings menu
3) Expand "POST behavior"
4) Select "Keypad (Embedded)"
5) Press the "By Num Lock" button
6)Press "Apply"
7)Press "Exit"

Hello,

You may refer to the user manual mentioned below to turn ON the wireless switch for your Dell Latitude E6500:

Press the Function Key (FN) and the F4 Key at the same time.

Hi

You can try the FN+Number lock which is quite often or the FN+F11
also FN+Screen lock which is quite often FN+F12. Let me know the respond.

It's a small button on the right. See http://support.dell.com/support/edocs/systems/late6500/en/sqrg/pdf/U084C0MR.pdf page 7 and 8

The lock 9 is for num lock.

Usually there is a 'Fn' button on the keyboard of a laptop. It has to be somewhere near the 'ctrl' 'windows' or 'alt' button on the left.

If you press and hold the 'Fn' key and then the numlock 9, you will toggle numlock on and off.

The 'Fn' of the key is normally written in another color. There are several buttons on the keyboard thet has a same color number or sign. To enable this signs and numbers, you have to press and hold the 'Fn' key and then the key with the desired number or sign.

Not knowing what the symbol looks like, it is hard to say.
You have to press and hold the "Fn' button to enable the function

In most cases it is to change resolution and/or display options, if it is a sign with two rectangles / one rectangle.

Used to change resolution when connecting a projector or other external display

hi you should find this on the under side of the laptop on a sticker, i gather you mean the serial number to the actual unit and not the serial number to your windows os...hope that helped

Try memory modules individually. See if any change.
Also post whether the Lock LEDs are solid or flashing
