Your Laptops Power Supply
Knowing what makes up your laptops power supply as well as what each part does for your computer can be very helpful information when it comes to maintaining your laptop computer. Many costly repairs can be avoided by obtaining a rudimentary understanding of how your computer's power supply functions. One of the most overlooked components of your computer's power supply is the cooling fan. It's role in powering your computer is to make sure that the components in your laptop do not overheat. Usually, the hottest part of your computer is the processor. This is important information to know if you ever decide to upgrade your laptop or notebook computer. Ask whoever is working on your computer whether or not the fan that is currently installed in your laptop is going to be strong enough to properly cool your computer. If you find that your computer is suddenly powering off for seemingly no reason at all after a predictable amount of use, chances are pretty good that a cooling issue is what is responsible for your power issue. Usually connected to the motherboard, the power board is one of the central pieces of your laptop power supply. It serves as a traffic conductor for the power in your computer. It takes the power from the power cord and directs it to both the battery as well as the mother board. It can also serve to regulate the amount of power circulating between components in your computer. Don't expect the power board to serve the same function as a power strip though. A surge protector is a necessary component to make sure that your computer's circuits don't get fried in the case of a power spike. If you look at your laptop's power cord, you will notice a rectangular box that is halfway down the cord. This is the AC adapter which turns the alternating current from the wall and turns it into direct current which is the type of current your computer uses. It also serves to make sure that there isn't too much power flowing into your computer. Usually, this box will have a light on it in order to let you know that power is running through it. This is valuable if you are ever having issues with your power supply. If your laptop's battery is dead, and everything is plugged into the wall and the light in the AC adapter isn't on, this tells you that the power issue is somewhere after the midpoint of your cord. Either the line is disconnected in your cord, or possibly there is a power issue in your house that isn't allowing power to flow to the wall jack. As you can see, having a basic knowledge of the parts and functions of your laptops power supply can be a very beneficial thing and may someday help you to either diagnose problems with your computer or help you make sure that if you do need a replacement part, that you are purchasing the right component.
