Initiating your troubleshooting process with the simplest solutions can be beneficial. Execute a hard reset by pressing and holding the power button for 10 to 15 seconds, which compels a shutdown and subsequent restart of the device. This straightforward step may rectify occasional system malfunctions leading to black screens.
Move on to verify that your display is active. Observe whether its power indicator lights up as confirmation of it receiving electricity. At times, a monitor might just not be switched on or properly connected to power. Scrutinize all video cables too, checking carefully for any damage or loose connections that could disrupt the consistency of your display.
Should these efforts leave your monitor still unresponsive, attempt plugging it into an alternative electrical socket or consider swapping out its power cable altogether. These minor adjustments have potential in swiftly pinpointing and fixing issues without Complexities arising.
Before Windows Login: Fixing Black Screen Issues
If you experience a black screen prior to the Windows login, the problem often stems from either startup settings or hardware connections.
These instructions will assist you in inspecting and modifying these settings in order to fix the problem.
Check Startup Settings Screen
It’s crucial to examine the startup settings screen if you encounter a black screen. The boot process may be hindered by improper setups or sequences within the BIOS/UEFI, leading to a black screen. A reset of these configurations to their original defaults can typically fix problems linked with incorrect settings that might provoke a black screen.
When starting up, access the BIOS/UEFI interface by tapping the designated key (commonly F2, DEL, or ESC). Look for and select the option that allows you to revert all options back to their factory presets. By doing this reset procedure in your system’s startup settings, it helps ensure that it boots from the correct device first, which is essential for tackling issues related to a black-screen during start-up.
