If you buy a new adapter, you will probably be given a full 1 year warranty, but still if you go with a used adapter, make sure you get at least 15 to 30 days. Granted, to ensure that you are buying a good adapter that is exactly the same as the seller's declaration.
You may have a connection problem with the current power adapter, but one thing I recommend you do is try not to fix it yourself.

So when looking for a laptop power adapter, understand that its use is very important and a great adapter for powering your computer and it is very important. Be patient and be really careful.
