Laptop screens tend to collect dust, food particles and other debris that starts to look unattractive after a while. It’s important to use very gentle supplies to clean your laptop screen, since the LCD surface is easily damaged. Using a microfiber cloth and a simple solution of water and vinegar will do the trick if you don’t want to purchase a special screen cleaner.

1.Cleaning the Screen With A Microfiber Cloth

First, turn the computer off and unplug the power adapter and battery. Cleaning a screen that’s in use can result in permanent damage, so err on the safe side and turn everything off. Don’t just put it to sleep. Then get a microfiber cloth. This is made with a type of fabric that doesn’t produce lint, in addition to being very soft. If you use a washcloth, T-shirt or another type of cloth, it could leave extra debris on your screen or scratch it. Avoid using paper products as well. Never use a napkin, paper towel, toilet paper or another paper product, since these are scratchy and will damage the screen. Then wipe the screen gently with the cloth. Using one sweep of the cloth should take care of any dust and loose particles on the screen. Wipe gently without exerting much pressure, since if you press too hard you could damage the screen. When you wipe with gentle circular motion, you’ll be able to lift up some of the tougher spots. Never scrub the screen, or you could cause pixel burnout. Clean the laptop frame with gentle cleaning solution. If the area around the screen is dirty, you can use a standard household cleaning solution and a paper towel; just be very careful not to let it touch the screen.

2. Using a Cleaning Solution

First, turn the computer off and unplug the power adapter and battery. Since you’re using a liquid to clean the screen in this method, it’s important to turn off the computer and unplug it from the outlet. Create a gentle cleaning solution. The ideal solution is plain distilled water, which contains no chemicals and is gentle on the screen. Make sure you use plain white vinegar, not apple cider vinegar or any other kind. Put the solution in a small atomizer bottle. This is the type of spray bottle that you push from the top to get a fine mist, similar to a perfume bottle. Pour some of the solution into the spray bottle and screw on the top. Don’t use this to spray on the screen itself, however. Apply a minimal amount of the solution to a microfiber cloth. A static-free, fiber-free cloth works best. Remember not to use regular cloth, since this could scratch the screen. Do not soak the cloth; you just want to get it moist, which is the purpose of using the atomizer bottle to wet it. A wet cloth can drip or run when cleaning the screen and the solution can weep behind the bezel and permanently damage your screen. Try applying the solution to just one corner of the cloth at a time, to make sure you don’t get it too wet. Wipe the cloth against the screen in a circular motion. Rapid circular movements generally eliminate streaks. Apply a gentle and even pressure to the cloth. Use only enough pressure to keep the cloth in contact with the screen.

Japanese paper folding inspires development of flexible battery that could transform the wearable technology industry.

The emergence of wearable technology and devices such as smartwatches and fitness bands has brought with it a need for a new type of battery, one that is flexible – and that’s exactly what researchers in the US have developed.

A team at Arizona State University turned to origami as inspiration for the design of a new lithium-ion battery, specifically a variation called kirigami, where the paper is cut as well as being folded.

Using kirigami techniques allowed the team to develop a flexible lithium-ion battery that could be stretched to 150% of its original size, without losing capability.

The team used the battery to successfully power a Samsung Gear 2 smartwatch, by sewing it into the elastic armband connected to the timepiece.

Even when the test subject flexes his arm, the watch still works.

Stretchable batteries could be sewn into fabrics – even clothing.

Hanqing Jiang, associate professor at the university, believes the battery’s versatility could change the design of wearable devices. “This type of battery could potentially be used to replace the bulky and rigid batteries that are limiting the development of compact wearable electronic device.”

The team says the battery can easily be mass produced, paving the way for more intelligent, technical clothing.
