A laptop charger, also known as a laptop AC adapter, is a power supply unit for laptops. It converts AC (alternative current) to DC (direct current), powers all elements within a laptop and charges the laptop battery.
Generally, it is not recommended that you use the charging unit of one laptop with another model. However, if you know what you are doing, you will have to make sure that the power ratings on both computers are the same and the power supply units for both have the same output ratings. Usually, similar models from the same company will have a similar or identical charger. So for example, a Dell laptop charger will usually charge its contemporary Dell models and laptop charger for Acer will charge common Acer models. But still make sure to match the ratings because sometimes there will be models with lower or higher voltage ratings and the wrong voltage can damage the system and the battery.
Different regions of the world have different domestic power supply voltages. This varies between 110V and 240V across the world. Most modern chargers come with a variable rating that makes it fit to be used in almost any part of the globe. However, it is always wise to check for the rating on the laptop AC adapter before plugging it in when in a foreign country. The information should both be printed on the body of the adapter and written on the manual that came with the laptop/notebook.
A difference in sockets has no effect as long as the voltage rating is permissible. If your charger doesn't come with interchangeable heads you might want to purchase one from the local electrical supplies shop.
First, check the wall socket for power. Try different wall sockets to be sure. Once you are sure that it is the charger which is at fault, check for the power ratings. Do they match or allow for the voltage rating of the power supply in the wall socket? If it does not, that might be your problem. If it matches, it is time to check the wires.
Some laptop chargers have a separate cord that needs to be connected with the ‘power brick’. See if this power cord is properly attached. Also check if the other end is properly plugged into the laptop. Sometimes a loose plug will cause the laptop to not receive charge. Another common reason is fraying of the wires, where internal wires break and hence disrupt the power supply. In this case you have to replace the damaged wire. If it is not the wires, then it is possible that the main power converter inside the adapter is at fault. This is when you have to get a replacement laptop charger. Getting one is easy. You just have to click your laptop manufacturer’s name or use our targeted search to land on the exact model.
