How to turn on numlk for gateway NE56R31u

You may have hit a certain combination of keys on your Gateway laptop and turned on the NumLock function accidentally. The result is that the rectangle of keys from the 7 key down to the question mark key have become a number-entry keypad. Worse, Gateway manuals don't discuss this function.

Hold down the "Fn" key on the bottom row of the keyboard, and press the "NumLk" key. Type the letters UIO. If they come out as numbers, move on to the next step. Hold down the "Fn" key and press the "F11" key. Type the letters UIO. If they come out as numbers, move on to the next step. Hold down the "Fn" key and press the F11 key and "Scroll Lk" key simultaneously. Type the letters UIO. If they come out as numbers, move on to the next step. Hold down the "Fn" key and press the "F9" key. Type the letters UIO. If they come out as numbers, move on to the next step. Hold down the "Fn" key and press the "Scroll Lk" key. Type the letters UIO. They should come up as letters. If none of these help, then it's probably a keyboard malfunction and you'll need to get it repaired.

Black Box in the lower portion of the screen will not disappear

Check your Closed Captioning settings in the menu. I would bet money you have the "Text" feature enabled. Change it to OFF and you should be all set. I hope this was of some assistance.

Can you pull all data off of it? Is it still under warranty? If not find a computer on e-bay, pull the hard drive out of it and reinstall your hard drive in the new computer, buy an external 2 1/2 inch hard drive enclosure enclosure for the hard drive from the new computer. Thre is more than likey mother board problems.

Vizio 42" LCD - Random appearance of small black rectangles

There is a processing fault that is starting to occure. What you are seeing is a type of aliasing. This can be in the main signal processing or in one of the control areas.

The set will require service. The service rep will test the set by using board substitution. There are typicaly a number of areas in the TV set that can cause this type of fault. Once the defective board is located the fault will be easy to service with a simple board swap and some adjustments.

If the set is out of warranty, it may be expensive to service. With many of the no-name brands, spare parts can be difficult or impossible to have.

Black Rectangle on lower half of TV screen.

Turn off the closed captioning feature. If a channel or program doesn't provide the captioning, all you get is the black box. Just find the menu page for that and change the setup.
