Power issues may be caused due to faulty ac adapter or charger, faulty battery, frayed or damaged power cable, faulty power button, or a system board failure.
Follow the troubleshooting steps below. Expand the sections below to learn how to perform each troubleshooting step to identify the cause of the power issue on a Dell laptop.
Most often, restarting the computer resolved many issues. The residual power in the computer may cause the laptop not to turn on. Follow the steps below to drain the residual power.
If this did not resolve the issue, go to the next step.
The AC adapter cable and power cables may get frayed or cut, and wires may become exposed at either end of the cables. This may be due to the way the cable is wrapped around the AC adapter, or if the cable is subject to undue stress. If the damage is severe enough to expose wires, you should discontinue using the AC adapter. To check the AC adapter, cables, and adapter port on the laptop for any damages:
To learn more, see the Dell knowledge base article Identify AC Adapter Damage on Dell Systems.
If you notice damage, contact Dell Technical Support for repair options. If you do not find any damage, go to the next step.
If the wall outlet is working correctly, go to the next step.
Reseat the AC adapter by following these steps:
If the AC adapter LED indicator is on, go to the next step.
If the AC adapter LED indicator is off or turns off when connected to the laptop, contact Dell Technical Support for repair options.
Ensure that you are using the original AC adapter that was shipped with the laptop. Using an AC adapter from other laptops or one that has a lower wattage may cause the following issues:
Dell laptops may use either a 45 W, 65 W, 90 W, 130 W, 180 W, or 240 W AC adapter. For optimal performance, use the original AC adapter that came with the Dell laptop. The AC adapter wattage information is printed on a label that is on the bottom of the AC adapter.
If this did not resolve the issue, go to the next step.When using a docking station, it is essential to isolate if the docking station is causing the power issue. Universal USB docking stations do not provide power to the laptop. The AC adapter should be connected to the laptop. For Dell Thunderbolt or E-Series docking stations, verify that the original AC adapter that is shipped with the docking station is connected to the docking station.
If the laptop is turning on without the docking station, see the docking station manufacturer's website to troubleshoot the issue with the docking station. For troubleshooting guides of Dell docking stations, see the Dell knowledge base article Guide to Dell Docking Stations.
If this did not resolve the issue, go to the next step.
Certain Dell Inspiron, Latitude, Vostro, and Precision laptops are equipped with a motherboard-integrated self-test (M-BIST). M-BIST is an integrated diagnostic tool that helps identify computer board-embedded controller (EC) failures. M-BIST must be manually initiated before Power-On Self-Test (POST) process and can be initiated on a Dell laptop that is not able to turn on.
