Performing a Hard Reset and Running a Hardware Diagnostic Test:
If your Dell laptop is experiencing a black screen issue, there are a few steps you can take to troubleshoot and resolve the problem.
1. Start by performing a hard reset. To do this, disconnect the laptop from any power sources, remove the battery if possible, and hold down the power button for 15-20 seconds. Then, reconnect the power source and try turning on the laptop again.
