I'm sorry to hear about the issues you're experiencing with your laptop. Blackouts on the browser and screen can be caused by various factors, including hardware or software problems. Let's try to troubleshoot the issue.
First, it's essential to determine whether the problem lies with the laptop or the operating system (OS). To do this, try using different browsers to see if the blackout issue persists. If the problem occurs in multiple browsers, it's more likely to be a hardware issue. However, if the issue is only present in specific browsers, it could be related to the software or browser settings.
Next, check if your laptop's power settings are affecting the screen display. Adjust the power settings by going to the control panel and searching for "Power Options." Make sure that the display is set to never turn off or adjust the on-screen timeout.
Additionally, it's worth updating the graphics driver on your laptop. Outdated or faulty drivers can cause display issues. Visit the Lenovo support website, locate your laptop model, and download the latest graphics driver for your specific operating system. Follow the instructions provided to install the updated driver.
If updating the graphics driver doesn't resolve the issue, you might need to consider contacting Lenovo's customer support again. Explain the steps you've already taken to troubleshoot the problem and ask for further assistance. It's essential to communicate your dissatisfaction with their initial support to ensure clear expectations for resolution.
If Lenovo's customer support remains unresponsive or unhelpful, you can contact the store where you purchased the laptop. Explain the ongoing issue and your previous attempts to resolve it. They should be able to assist you further or guide you on how to escalate the situation.
Remember to provide specific details and any error messages you encounter when describing the problem. This information will help the support team diagnose and address the issue more effectively.
Overall, it's difficult to determine whether the problem is with the laptop or the OS without further investigation. By following the troubleshooting steps and seeking appropriate support channels, you should be able to resolve the issue or receive appropriate assistance.
