To Recycle Or Not To Recycle Laptop
Nowadays, computer technology is developing at a very fast pace. Prices have become affordable. Consumers cannot resist the temptation to replace computer systems too often, sometimes neglecting the importance of environmental care. How to help keeping the balance between a technical progress and ecological protection?
The reasons why people rid of old laptop computers can be different - obsolete models, broken or malfunctioning parts, or the combination of many factors. A fast developing technology makes computers outdated at a very quick pace. An additional factor, why people are prone to look for the replacement of currently owned laptop, is low prices. Decreasing prices make it affordable to replace the old computers more often with the latest improved ones.
A laptop computer is a complex system. Since it consists of many parts, the probability that one part can be out of order within a finite period of time is quite high. To make it more clear, let's do a simple math for a single notebook. If probability for one part to fail within one-year period equals, for example, only 0.01%, and the notebook has, for instance, 1,000 parts, the chance of failing one of the parts in a single laptop is around 10% (0.01*1,000). Now let's assume there are 10,000 laptops that people bought in a city. Since the probability that one laptop in each group of 10 has 100% chance to be broken, we get 1,000 broken laptops annually. We could estimate the number of broken laptops worldwide every year. This number is huge - the millions of broken laptops.
Besides the complexity, laptops are pretty fragile devices. A small defect or even damage can be easily introduced by users. So what would you do if only some particular part of your laptop is broken? What if laptop's warranty has expired or does not cover the part replacement? Would you try to find some place to repair? Despite the obvious benefit of repairing - money saving, some people say that it is easier to look for a new laptop. Of course, it is up to user if it is time to say good-bye a non-fully functional or defective laptop. But if you decided to throw out your old PC, think about recycling.
Why is it vital to recycle old laptop computers? When computers decompose, dangerous chemicals contaminate the water supply and the air. The disposal of old computers is a serious problem. If even a very tiny battery can make soil seriously contaminated and causes a water pollution, a much bigger laptop battery creates much more troubles, not to mention about other parts of computer. Additional problem is a growing demand for laptops because their production pollutes the Earth.
First of all, if your computer is still functional, consider donating it to someone, to a charity, or budget-limited organization. If you are buying a new laptop, sometimes the option is to recycle an old one at store. Now many manufacturers offer different computer recycling programs. If your computer is still in a good shape, they may even refurbish it and re-sell. Nevertheless, most components inside of the computer contain valuable resources that can be reused.
Computer technology is moving now at a breakneck speed, sometimes diminishing the importance of environment protection and care about our green planet. Fortunately, more and more laptop users become ecological-minded. They understand that recycling helps converting used materials into new products to prevent waste of potentially useful materials and reduce the pollution of the Earth. Some of them have found places to repair; others have learned how to replace broken screen, keyboard, and other parts on their own.

Common LCD Screen Cleaning Mistake
Question:
I sprayed Windex on my laptop LCD screen and now it has pink streaks. Is it possible to remove the pink streaks from the screen using a stain remover?
Answer:
Pink streaks on your screen are not paint or dirt and cannot be erased by stain remover. Since Windex is a solvent, the pink color is a result of dissolved surface of the screen. Every LCD panel has a coating on top of the actual screen, this is what is damaged. It is hard to believe that you can easily rid of these streaks. However, the LCD screen in a laptop is easy to remove and replace. You may learn from some on-line guide how to replace LCD screen.
For your information in the future. Despite the fact that the technology is changing fast and screen coatings are different, in general, it is not recommended to use any solvent including alcohol. It is better to use distilled water. Shut down your laptop before cleaning. Using a lint-free microfiber cloth is best, an old cloth can introduce dust. After cleaning dry a wet screen with a dry cloth. Read more How to Clean LCD Screen

New Screen Demonstrations at the Society of Information Display 2010
Society of Information Display (SID) held 2010 International Symposium, Seminar, and Exhibition from May 23 to May 28, 2010 at Washington State Convention Center, Seattle, WA, USA. The SID, that is now in its 48th year, is the major international event for scientists, engineers, manufacturers, and users in the electronic-display industry. Below is a brief review for only three of many products presented this year.
Samsung has presented an ultra energy-efficient USB-powered monitor. It is an 18.5" LCD display capable of running exclusively from USB - no adapter required. It is an extremely energy efficient display. Built with LED backlight, Samsung has been able to drop the peak power consumption down to only 6.3W. That is why the device can function from bus power over USB.
SONY has introduced a rollable (bendable) OLED display. The flexible OLED measures 4.1" and is only 80 micrometers thick. To reach the goal of a rollable display, SONY developed OTFT - organic TFT (thin film transistor) with original organic semiconductor material. The rollable OLED has a resolution of 432x240 pixel, 16.8 million colors, and contrast ratio 1000:1.
LG has showed the largest 3-D display in the World. This display is a gigantic 84" ultra high definition (UHD) 3-D panel with 3840x2160 resolutions. That is four times the resolution of previous full HD TV panels with (1920x1080). To enable watching in 3-D, the display requires a polarized glasses.
