If you rely on your Dell laptop for work or use it a lot every day and have to recharge it frequently, the inevitable will happen, and your Dell laptop charger will stop working. So you'll have to buy a new one, which may be more complicated. That is why, if possible, you should try to fix the problem yourself. To check out the Dell Precision 5550 Review, click here

Here are some pointers to get you started:

1. Warranty —The first thing you should do in this situation is check to see if the computer and accessories are still covered under Dell's warranty. You can do this by searching for the phone number on Dell.com. A word of caution here: make sure you call the Dell helpline. If you're lucky and your Dell laptop charger is still under warranty, all you have to do is send it to them, and they'll take care of the problem. If this is not the case, move on to step 2.

2. Examine the power supply — The next step is determining whether the issue is with your AC power supply. It's not difficult to figure out. Simply plug the AC adapter into a wall outlet, and if everything is working correctly, you should see the light on the transformer unit. If you don't see this light, the transformer has failed.

3. Electrical Meter — Get an electrical meter and use it to probe the ends of the AC adapter to see if any electricity flows through the transformer.

What if you don't have a power meter? You don't have to go out and buy one right away. Perhaps a friend or acquaintance has one, or better yet, go to a local electronics store. They not only know how to perform the testing, but they also sell the transformers. They will perform the testing at no cost to you.

Another idea: If you have a friend who owns a Dell computer, try plugging your transformer into their machine to see if it works. If not, your transformer is most likely dead.

If it turns out that your transformer isn't the source of the problem, it's almost certainly your computer.

4. Repairs — Your Dell Laptop Charger may be simply broken and can be repaired yourself. If your best efforts have failed, and your warranty is still valid, ship it back to Dell so that they can repair or replace it. Otherwise, you'll have to buy another one on your dime.

You can still send the charger back to Dell, and they will repair it for you, but it will be costly, and it is probably better to just get a new one.

5. Shipping — When packing your Dell Laptop Charger for return to Dell for repairs, ensure you do so carefully so that no damage occurs while it is in transit. Any damage must be addressed separately with the shipping company, which may result in your charger having to be replaced at their expense.
