  • Issues

  1. Power conditions

  • The most common type of AC power adapter involves a small box, with one wire to go to the computer and another wire to go to the wall.
  • There is usually an LED light on it, to tell you that it is on.
  • Apple notebook power adapters often have an LED that is actually built into the side of the computer, not into the adapter box, so obviously it won't light up when it's not connected to the computer.
  1. Video

      • Screen problems come in a variety of types, each one indicating a unique cause.
      • A completely black display indicates that the connection between the screen and the motherboard is loose or disconnected.
      • Thin lines across the display are caused by a slightly loose connection to the motherboard. A dim image is most likely due to a failing backlight.
      • Growing stains or blotches are a sure sign you need to replace the screen. If the display degenerates or scrambles after you have been working for a while, the computer is overheating.
      • Dead pixels, which show up as tiny black, white, or solid-colored dots on-screen, are common, but there is no fix. However, many manufacturers will replace a notebook’s display after a certain number of pixels die.
  2. Keyboard

    1. *** Restart your computer. This should always be attempted first for any type of computer malfunction.
      • Check the connections for your laptop . Is the battery indicator light on the laptop on? Is the computer AC adapter, if in use, plugged soundly into your power outlet? You may be trying to wake your computer up from sleep via a keyboard press, but there may be no power reaching your laptop whatsoever. Try switching power outlets in case one individual outlet is malfunctioning.
      • Look at your dell computer closely. Flip your laptop over. One of the leading causes of keyboard failure in Dell laptops are the screws in the bottom of the laptop case. Locate a small Phillips head screwdriver, and tighten those screws up. For many people, this may solve the problem.
      • Consider replacing the keyboard of your Dell computer, if possible, if none of the above work and there is no other obvious problem. is a good place to start to order parts depending on your laptop-for further parts information, also check the documentation that came with your laptop. Get your replacement laptop in hand, and lay your laptop flat on an even surface.
