Computer is locked in the green symbols of the keyboard

Hi. Please do troubleshooting steps below:

1. Check to be sure your "Number Lock" or "Function Lock" keys aren't lit. These can lock out certain parts of your keyboard. If either of these is lit, press them to unlock the locked portion of your keyboard. These can be found at the top right on a laptop and between the number pad and main keys on a desktop keyboard.

2. Save all open programs using your mouse. Use your mouse to restart your computer. This will only work if your computer isn't frozen. If your mouse doesn't move, press the power button on your Dell until the computer turns off. Press it again to restart. If the issue was lack of memory or a locked program, this will unlock your keyboard. Continue to Step 3 if the keyboard is still locked.

3. Shut down your computer using your mouse or power button. Don't restart. Unplug your Dell.

4. Remove the battery if you're using a laptop by turning the laptop over and sliding the battery release latch. Slide the battery out and replace after one minute.

Have a good one!
