What should I check first if my laptop screen won’t turn on?
If your laptop screen isn’t turning on, the first step is to check if the laptop itself is powering up. Look for any indicator lights that show the laptop is on. If percussive sounds are heard, or if the keyboard lights up, it indicates that the laptop is receiving power. You might also want to ensure that the battery is charged, as a drained battery can prevent the screen from turning on.
If the device appears to be on but the screen remains black, try to reset the laptop. Disconnect all peripherals, including the power adapter, and hold down the power button for about 15 seconds. This can sometimes clear temporary states that might be causing the screen to remain off. After this, reconnect the power and attempt to start the laptop again.
How can I tell if the issue is with the laptop screen or another component?
To determine whether the issue lies with the laptop screen or another component, connect your laptop to an external monitor through the HDMI or VGA port. If the external monitor displays your laptop’s screen correctly, it suggests that the screen itself or its connections may be faulty. In this case, further investigation into the internal screen components or cables would be necessary.
If the external monitor does not show any image either, the issue could be related to other hardware components, such as the graphics card or motherboard. You might then want to check for any signs of failure in these components or seek professional help to diagnose the problem more accurately.
