Replacing a screen and its inverter electronics is a tough job that can cost several hundred dollars and take hours. For an old system, it is likely not worth it. But if the display is only slightly scratched, it is a no-brainer to fix it.After a trip to the beach on a windy day last summer, I noticed a bunch of small scratches and one big one on the display of my PC. The scratches annoyingly obstructed the screens image.These types of scratches can be smoothed out with a dab of toothpaste (and I do mean toothpaste -- the gel varieties usually dont have the necessary abrasives) and a little elbow grease.Gently rub toothpaste into the scratches.Rub the toothpaste between your thumb and forefinger and it should feel slightly sandy and gritty. It is these mild abrasives that will fix the screens problem.Gently rub the toothpaste in a circular motion over the scratches for a few seconds (not too hard -- you could rub off the screens surface coating).Then wipe the screen clean with a soft cloth.While the large scratch is not gone completely, the smaller ones are.Finish up by cleaning the screen with a non-ammonia-based window cleaner. My favorite is Sprayway, but there are grocery store shelves filled with these products. Look it over and if the scratches are not gone, repeat the process.This strategy is not perfect. With my netbook, the toothpaste only partially removed the big scratch, but it did get rid of all the minor scratches. Plus my netbook now has a minty fresh aroma.

        Why is it that when there is a glass of water or coffee to be spilled, a notebook is generally there? Call it Murphys Law of Mobility, but I have seen several notebooks die because of spills.If you have spilled a soda or a caramel macchiato into your notebook, you are probably out of luck. Anything with sugar is death -- once it dries it is there forever, eating away at your systems components. At that point, you could send it to a professional to use deionized water and a lot of patience, which can take weeks, but you're probably better off just pulling out the hard drive and buying a new machine.If it is just water or non-sugared coffee that you have spilled, your chances of saving it are much better. Although it is important to act quickly, the worst thing you can do to a wet system is start it up right away to see if it works. If there is water inside, you run the risk of creating an electrical short and potentially causing permanent damage. The thing to do is to calm down and dry out the system before hitting the power button.Quickly unplug the machine and take out all of the easy-to-remove components like the battery, CD drive, hard drive and keyboard, and set them aside to dry separately. (You will need a screwdriver to remove some of these parts, consult your manual for instructions.)Carefully tilt the laptop on its side to help the water drain out.Tilt the system on its side to help drain the water out. Do yourself a favor and put a towel underneath. Try to keep the liquid away from the display as you are removing parts and draining the system.Gently shake the system to get liquid out of the many nooks and crannies inside, the air vents generally act as water canals. Next, use a can of compressed air to blow the inside of the case as dry as possible.Use compressed air to help dry the insides.It is a good idea to let the machine sit near a heating or cooling air vent overnight -- or longer if you can stand the suspense -- to fully dry it out.When you are sure the system has dried out, put it back together, start it up and hope for the best. If it starts OK, let it run for a while to remove any remaining condensation or droplets. If it does not start up, it is time to consider getting a new machine.

        Because a notebook that travels needs to be plugged in and unplugged several times a day, the cord and connector can take a beating, leading to a frayed power cord. If this happens, it is important to get a new cord or fix it right away, because it not only can damage the systems battery through intermittent charging, but it can also be a fire hazard.Fortunately, most power adapters have removable AC power cords, which cost a few rupees and are available at stores. On the other hand, if the connector that plugs into the computer is the problem, it can cost a hefty amount to replace because you have to find the exact AC adapter for your laptop from your notebook manufacturer or an online retailer. (search for your make and model name followed by AC adapter).Or you can just fix it yourself.To protect the surface you are working on, lay down a wide strip of painters tape, sticky side down, and place the frayed area of the cord on top of it. The sealant wont stick to the back of the painters tape the way it might to other barriers made out of paper or plastic, and the painters tape should peel right off the table when you are done. (Note, however, that you should not be doing any kind of computer repairs on your good furniture).Next, squeeze out a gob of sealant onto the area that needs fixing. Work the gooey sealant into place, covering the damage with a liberal coating. If you have sensitive skin, it is a good idea to wear thin protective gloves for this part.Let the sealant cure for an hour or two until it is firm. Gently remove the cord from the tape (and the tape from the table), and you have the equivalent of a new power cord that's flexible and ready for years of road work.
