Laptop Will Not Turn On
Your laptop will not turn on.
Check if your laptop is charged. If you are unsure whether your laptop is charged, plug your power adapter into an outlet and into your laptop. When you plug in the power adapter to your laptop, a light should appear on your adapter to show your adapter is ready to power your device. If no light appears on your adapter, check if you need to plug in the adapter to a different power outlet or if your adapter is not plugged into your laptop correctly. If your laptop still does not turn on, you can try removing the battery from your laptop for a while before attempting to turn on the device again. See this Dell article for videos and more information on how to resolve this issue.
If your laptop does not turn on even when it should have enough power, the cause might be battery failure. Verify whether your laptop is experiencing battery failure by plugging in your adapter and observing how your laptop reacts. If your laptop does not turn on, or turns on and shows signs of not charging properly, you may need to replace a dead battery. Follow this guide to replace your battery.
