Step 1: Check power to the outlet.
You should do this very simple and quick test before trying to potentially waste a lot of time troubleshooting something on the laptop.
Step 2: Check your laptop power cable.
Normal wear and tear from wrapping up your laptop power cable can destroy internal copper connections that bring power from your wall outlet to your laptop. You should look at your laptop power cable plug and see if there is any damage. Look inside the plug that connects into the port of the laptop. You need to replace the cable if this is damaged.
Step 3: Check your laptop power port.
You need to plug in your cable and gently see if it wiggles easily. If you notice the power plug can move without moving the laptop, then you may need to replace the laptop’s power port. For some laptops, you need to desolder the power port to remove it. Other laptops make this an easy repair by using a screw to fasten it down.
Step 4: Look for Burns.
Unfortunately, capacitors and MOSFETS can burn out and kill your system board. When that happens, you will likely need to submit a warranty claim if your device is covered or buy a new laptop.
