Check power supply One of the first things to check when your laptop is not turning on is the AC adapter (power cord). Examine whether there are any issues with the adapter. Check if it is connected to the electric socket. Take a good look at the adapter’s wire for any damage? If it has any sort of damage that is disrupting the electric supply, you should replace it. Don’t continue using a damaged AC adapter for safety reasons.

Faulty screen If there are no issues with the power supply and you’ve tried replacing any faulty AC adapter, and are still unable to get the laptop running, there might be issues with the laptop’s screen. Here’s how you can check:

First power on the laptop. Check if the power indicator LED is lit. If you can hear the laptop fan and other noise and the screen still isn’t displaying anything. It is possible that the laptop’s screen is faulty and needs a replacement

Press the power button for 10 seconds to turn the laptop off. When you see the manufacturer’s logo during startup, press the power button for 10 seconds again. Repeat this another two times and Windows will automatically boot into safe mode
