2. Check for External Damage

Inspect the Chromebook's screen for any physical damage. Even minor cracks or impacts can cause display issues. If you notice any damage, proceed with caution, as repairs or replacements may be necessary.

3. Connect to an External Monitor

If possible, connect your Chromebook to an external monitor. If the line appears on the external monitor, the issue may be with the graphics card. If the line does not appear on the external monitor, the problem is likely with the Chromebook's screen itself.

4. Update Chrome OS

Ensure your Chromebook is running the latest version of Chrome OS. Go to Settings About Chrome OS Check for updates to update your system.

9. Contact Support or a Professional Technician

If the line persists after trying these steps, it may be a hardware issue such as a faulty display cable or screen. Contact the manufacturer's support team or a professional repair service for further assistance.
