Hardware Issues
Before we dive into the troubleshooting process, let’s examine the possible hardware-related causes of a laptop screen not turning on.
- Power Supply: A faulty power supply can cause the laptop to shut down or not turn on at all. Check the power cord and ensure it’s properly plugged into both the laptop and the wall outlet.
- Battery: If your laptop has a removable battery, try removing it and plugging it back in. This can help determine if the battery is the culprit.
- Motherboard: A faulty motherboard can prevent the laptop from turning on. Inspect the motherboard for any signs of physical damage or wear and tear.
