The LED power supply is necessary for charging a laptop and can be used anywhere with AC power. It consists of an AC power adapter and cables, with some having an LED light to indicate if it’s working. Troubleshooting may be required, and users should avoid exposing it to heat or moisture.
The light emitting diode (LED) power supply supplies the electricity needed to power a laptop. Charging a laptop is the most common use and without the LED power supply the laptop will not function once the battery power is depleted. The alternative to a laptop power supply is a laptop charger, where the user replaces the battery to charge it while another battery is in use. This is often an inconvenient option for the LED power supply, which can be plugged in anywhere that has AC power, such as an electrical outlet. Some laptop power supplies are compatible for use in the car charger.
The components of an LED power supply are the AC power adapter and cables. One wire connects the ac power adapter to the electrical outlet and another wire connects to the laptop. It is often available in 120 watts and can be adapted for use on an airplane or in a car. Many adapters have an LED light, which indicates whether the LED power adapter is on or not working. Other laptops have the LED light built into the laptop itself and not the power supply, and some laptops have both.
Users of many types of power supplies have to troubleshoot them from time to time and the LED power supply is no exception. A common problem is that the LED light doesn’t turn on when the power supply is plugged into the wall and not into the laptop. It is often recommended that the user try plugging the power supply into a different wall outlet or using another cable to determine if the original power supply is no longer working. Users in rural areas may also experience peak power output at different times, which can damage the power supply. Connecting to a universal power source often fixes this problem.
There are also ways to ensure that the LED power supply works at its best. To begin with, users are advised not to pull the cords out of the wall outlet. It is often an electrical hazard to expose the power supply to heat or moisture. Dropping can often cause a faulty power supply and the only remedy is to buy a new one. When there is a problem with the LED power supply, users are advised to return it to the manufacturer or reseller and not to try to disassemble and repair it yourself.
