How to Change a DC Adapter for a Laptop -- go-shop.com.au

Personal computers (PC) and mobile devices such as laptops operate off of direct current (DC) energy. Standard household jacks, and almost all businesses in the United States make use of alternating (AC) current. This means that all computers need a special adapter (power supply) that will temporarily store a charge from the AC current to provide an even flow of energy to the DC input jack. These power supplies are composed of a multi-wire cord connecting to an AC/DC adapter, which then has a single direct-current cord that leads to the laptops DC input jack. If your laptop has trouble charging, or the light on your AC/DC adapter no longer turns on (they get very hot and burn out easily), it must be replaced.

Instructions

Step 1

Use the internet to select the proper power supply for your computer. Entering the model number of your laptop such as "Toshiba Satellite A505" and the words "Power Supply" in a search engine will result in a list of products you can use to replace your faulty power supply.

Step 2

Use the information you glean from your Internet search to purchase the proper replacement power supply. The best deals are typically online or direct from the manufacturer, but it is more convenient to go to a retail store to get a replacement part immediately.

Step 3

Disconnect your old power supply from the laptop. This includes the entire power cable and AC/DC adapter. You may be able to reuse the cords of your old unit, such as if they are longer.

Step 4

Assemble the new power supply that you purchased earlier. The AC cord connects to the AC/DC adapter, which connects to the DC cord, which finally connects to the laptop.

Step 5

Check the light on the AC/DC adapter is lit. This will indicate that the power supply is receiving power. You should also check your Windows desktop in the lower right hand toolbar for a power charging icon; it will look like a battery with a lightning bolt flashing on it.
