When to Get a New Laptop AC Adapter Replacement For Your Laptop depending on our usage or the inadvertent fluctuation of electricity supply, the ac adapter that was supplied with the laptop may or may not work after a while. If you’re in the situation where the ac adapter is not working, or the laptop is not getting powered on with your power adapter, you might need to go for a replacement ac adapter.

How would you like it if your original ac adapter started working, after you spent time and money buying the replacement? So, here are some ways you can check the condition of the adapter, before concluding that it is not functional.

Instructions

1. Check if the adapter is functional, after plugging it in to a power outlet, which obviously should not be the regular outlet. If it does, then for now you don’t need to buy a replacement adapter.

2. Connect the ac adapter cable into the laptop firmly, and check if you can power the laptop on. If yes, then there is no need for a replacement.

When these tests fail, you will need a replacement adapter.

• How to select the right replacement ac adapter?
• There are a few specifications that you need to keep in mind, while hunting for a replacement adapter – voltage, output power and proper connectors. If these, I mean all of them, do not match the specifications of your computer, chances are that you will be taking your computer to ruin. You need to check if the replacement adapter is compatible or not.VoltageHow do I know my laptop’s voltage requirement? This is very simple. Turn the system over and you should be able to find it listed at the bottom. There might be a sticker, or it could just be printed at the bottom. The way you can identify it, is by looking for a number, with a big ‘V’ next to it. That will be the voltage for your laptop. While searching for a replacement ac adapter, you need to look for this specification. The original adapter will also contain this information.

Current Output

The second thing to look for is the current output. The numbers will either have ‘A’ or ‘mA’ tagged along with it (4.5A or 9mA). These numbers will ensure that the electricity going to your system is acceptable and it will not cause any electrical problems.

Connectivity

AC adapters come with different connectors. You need to choose the one that fits your computer. If it doesn’t, you will not be able to power it up, and will be back to square one. Therefore, choose well.

What if you buy a DC adapter instead of an AC adapter? Be careful about this. Your laptop needs an AC adapter, and you need to get one.
