A Look at Replacement Chargers and Adapters for the Lenovo ThinkPad

Replacement chargers are a great way to hedge your bets against the possibility that the cord that came with your Lenovo ThinkPad may become misplaced or stop working properly. Without a charger, even a fully charged battery will only last a few hours under constant use. In order to protect against having to wait for a new charger to be able to use your ThinkPad, keep backup power adapters and chargers for Lenovo ThinkPad devices so that you can still get your work done.

What is the difference between an AC and DC charger?

The difference between these two types of chargers is the electrical current that they are able to use, which is either AC or DC. The difference between these two is simple: AC changes polarity at regular intervals while DC does not. What this means is that in alternating current (AC), the direction of electrical flow changes. However, in direct current (DC) circuits, the current always flows in the same direction. While this difference may seem minor, it necessitates different designs for the circuitry that the current flows through.

In general, these devices are not designed to run using the incorrect kind of current. Laptops by Lenovo use DC, but they can run off of the alternating current from wall outlets because it is converted to DC in the adapter before it ever gets to the computer. Thats what the box that is found in the middle of computer cords is for. It converts the current coming out of a wall socket into the DC that the computer needs to charge its battery and run the internal components.

What are the benefits of having a replacement power adapter?

There are several benefits to having a second power adapter available for charging your laptop. If you lose or damage your current charger, then you wont have to wait to find a replacement as youll already have one. If you regularly take your computer with you out and about, you can leave the backup charger in your car in case you forget to bring the original cord. That way, you can still use your computer without having to worry about running out of battery. Also, if your battery life is low, having a power adapter can be beneficial.

What charger is right for the Lenovo ThinkPad?

Finding the right charger for your computer is actually a simple process. By following some guidelines, you can be sure to get the right charger for your device with little effort.

  • Find the model number: Find the model number on your computer. It may be located on the bottom of the case or under the battery. Once you have this number, you have one of the most important pieces of information for getting a new power cord.
  • Compare the wattage: Your computer is designed to run with a specific amount of electrical current, and if the cord that you use is not designed to provide this same amount, there are risks of damage to either the computer or the cord or perhaps both. Make sure that you check the wattage requirements of your computer and the provided wattage of the cord and verify that they are the same.
