Laptops typically require 16-20V chargers. A charger with a different voltage may not offer enough electricity to power your laptop.

- Sometimes, the screen’s inverter failure causes the problem with the display. If this is the case, you could get the inverter replaced.
- Use an external monitor to test your laptop’s display. Plug-in your monitor, power up your laptop and immediately shut its lid. If this external monitor cannot connect to your device, then the issue goes beyond a damaged screen display.
