Visit the Lenovo Support website and download the latest BIOS update for your model. Run the downloaded file and follow the instructions carefully to update the BIOS. Ensure your laptop is plugged in during the update to prevent power loss.
Check if the Wi-Fi is enabled on your laptop and that Airplane mode is off. Restart your router and laptop. Update the Wi-Fi driver via the Device Manager, or download the latest driver from the Lenovo Support website.
Use Lenovo Vantage or the Lenovo Diagnostics tool to run a hardware diagnostic. These tools can be accessed from the Start menu or downloaded from the Lenovo Support website. Follow the on-screen instructions to complete the tests.
Check for any debris under the keys. Try connecting an external keyboard to test if the issue is with the laptop keyboard. Restart your laptop and update the keyboard driver. If the problem persists, consider contacting Lenovo support for further assistance.
Increase performance by upgrading RAM, using an SSD, and ensuring your operating system and drivers are up to date. Regularly clean up unnecessary files and programs. Adjust power settings to 'High Performance' mode for better CPU resource allocation.
