Your laptop adapter is an essential part of your unit

Choose Correct Adapter All adapters are not created equally. Check the voltage on your laptop. Then compare that to the voltage of the adapter cord you in which you are interested. If the voltage is too low, it will not power your computer, or it will short-circuit. This is especially true if you take your unit outside the country. Most outlets that power laptops outside the United States take 100 to 240 volts, as the website states. Take Care of Power Brick The power brick--which, according to the G-batteryshop website, is the black box in the center of your adapter--is a sensitive piece of equipment. It is a significant part of your adapter, for it is the part that receives the electrical charge and lets you know that your unit is on. Protect it by not jarring it or dropping it. Check for Objects If hard objects, such as books or your laptop case, are lying on the adapter cord--the effect is similar to that of a bent water hose, according to the G-batteryshop website. It could choke the flow of current in your cord, and keep your computer from powering on. Furthermore, as the Toshiba website indicates, you must keep your adapter cord straight as possible at all times to avoid damage to the wires inside. Avoid Heat Keep the cord in a cool place. The Toshiba website says to avoid placing it near heat sources such as electric blankets or heaters. Heat can travel into these sources, damaging the sensitive wiring in the adapter cord. Avoid Pinch Points As the Toshiba website points out, do not run your cord through any pinch points. This may include a door, a window or between a desk and a wall. This may not only disrupt the flow of current, but also damage the wiring inside the adapter. Grasp Plug Directly Never pull directly on the cord to unplug your unit. As the Toshiba website points out, pulling on the cord can not only possibly damage your adapter, but also could bring irreparable damage to you. You could incur electric shock, or even a house fire, by improperly unplugging your adapter. To prevent this, always grab hold of the plug itself.
