Your Laptop Only Works When It's Plugged In. Your laptop working only when plugged in is a sure sign that the DC power jack is not connecting well with the DC power port. Over time, the DC power jack can become loose, causing intermittent connections. DC Jack Repair is necessary to fix this issue.

The DC Power Port Is Damaged. If you see physical damage to the DC power port, likely, the DC power jack is also damaged. In this case, you'll need to replace the DC power jack and DC power port. 

Your Laptop Won't Charge. If your laptop doesn't charge, even when it's plugged in, there may be an issue with the DC power jack. You'll need to have it checked and repaired by a professional.

The Charging Light Doesn't Come On. If the charging light on your laptop doesn't come on when you plug it in, there could be a problem with the DC power jack or the battery. Try changing your computer from a different outlet to see if that makes a difference. If not, then you'll need to have your DC power jack repaired or replaced.

You Hear a Clicking Noise When You Plug in Your Laptop. A clicking noise could indicate that the DC power jack is loose and not making a good connection. It can eventually damage the DC power port, so it's best to get it fixed as soon as possible. 

Your Laptop Randomly Turns Off. If it turns off randomly, even when plugged in, this is often due to an issue with the DC power jack. It can become loose over time and cause an intermittent connection, leading to random shutdowns. 

The Battery Drains Quickly. If you notice that your laptop battery drains quickly, even when it's plugged in, this could be another symptom of a failing DC power jack. When the connection is loose, it can cause electricity to leak out, which will drain the battery faster than usual. 

The Screen Flickers. Many things can cause a flickering screen, but if it only happens when you move the DC power cord around, it's likely due to a loose connection in the DC power jack.

You Can't Turn On Your Laptop. If you plug in your laptop and nothing happens, no lights come on, and it won't turn on, then there may be an issue with either the DC power jack or motherboard. In this case, you'll need to take it to a professional for repair or replacement.

Another way to test the DC Jack is to use a multimeter to check for continuity. With the DC plug plugged in, touch one lead of the multimeter to the center pin of the DC Jack and connect the other lead to the outer shell.

If there's continuity, then the DC Jack is most likely shorted and will need to be replaced. If you're having issues with your DC Jack, there are a few ways to test it to see if it's the problem.

How To Properly Maintain a DC Power Jack

If you have a DC power jack that needs repair, there are a few things you can do to fix it. Here are 6  ways to properly maintain a DC power jack:

1. Clean the DC Power Jack 

One of the most common reasons a DC power jack to becomes loose is because it's dirty. Over time, dust and dirt can build up on the connection, making it harder for the adapter to make a good connection. You'll need to disassemble your laptop to clean the DC power jack.

2. Check The DC Power Adapter

If your DC power jack is loose, the problem may lie with your DC  power adapter. The DC power adapter converts AC power into DC power, and the DC power adapter can become damaged or defective. To test the DC power adapter, plug it into another laptop or a DC power supply. If the DC power adapter works on another device, then the problem is with your laptop's DC power jack.

4. Use Electrical Tape

If you're in a pinch and you need to use your laptop right away, you can temporarily fix a loose DC power jack using electrical tape. Wrap a few layers of electrical tape around the DC power jack and the DC power connector on the AC adapter. This will create a temporary connection between the two parts and should allow you to use your laptop until you can get a more permanent fix.

5. Use a DC Power Jack Replacement Kit

If you're not comfortable soldering or don't have the necessary tools, you can use a DC power jack replacement kit. These kits come with everything you need to replace the DC power jack, including a new DC power jack and instructions. Replacing the DC power jack is reasonably straightforward, but it's essential to follow the instructions carefully.

Then, you'll solder the new DC power jack in place. It is a more permanent fix, but it requires soldering skills.
