This problem can be seen as a dark spot that may have different size portions. Basically you have had dust enter you laptop and come to rest on the RGB film layer causing the colors from the pixel or pixels to be blocked.

Troubleshooting:

1. Gently shake the laptop in hope that the dust will fall out of the way of the pixels.

Troubleshooting:

1. Download a software called Pixelhealer here and run imaging software through the laptop to alternate the color patterns.
2. Gently massage the pixels with a soft cloth that are not showing appropriate colors. Generally only works with dark pixels due to the lack of electrical contact.

Misalignment basically means that the computer has had a major shock from being dropped or stepped on, etc. This shock has caused the pixels to move and display light in the wrong direction. Unfortunately, there is no fix for this other than replacing the screen. Click here for screen replacement guide.
