To perform a system recovery, restart your computer and press F11 during the boot process to enter the recovery environment. Follow the on-screen instructions to reset the system to factory settings. Ensure all important data is backed up before proceeding.
To clean the exterior, use a soft, lint-free cloth slightly dampened with water or a mild cleaning solution. Avoid using harsh chemicals. For internal cleaning, ensure the device is powered off and use compressed air to remove dust from vents and fans.
To upgrade the RAM, power off the computer and disconnect all cables. Open the side panel and locate the RAM slots on the motherboard. Insert compatible RAM modules into the available slots, ensuring they are fully seated. Reassemble and power on the system.
Check the power cable and ensure it is securely connected to both the computer and the power outlet. Verify that the outlet is functional by testing with another device. If the problem persists, inspect for any visible damage or consult a professional technician.
Visit the Lenovo Support website and download the latest BIOS update for your model. Follow the provided instructions carefully to install the update, usually involving running the update utility from within Windows or a bootable USB drive.
Ensure that the vents and fans are clean and unobstructed. Place the computer in a well-ventilated area and consider using a cooling pad. Check for any software updates that might address fan control or thermal management issues.
Ensure your graphics card supports multiple monitors. Connect each monitor to the available display ports (such as HDMI, DisplayPort, or VGA) on the computer. Configure the display settings in the operating system to extend or duplicate the desktop across the monitors.
Check for any background processes consuming excessive resources using Task Manager. Consider upgrading hardware components like RAM or switching to an SSD for faster performance. Regularly update software and drivers and perform disk cleanup to free up space.
Restart the computer and press the designated key (usually F1 or F2) to enter BIOS setup. Navigate to the 'Advanced' or 'CPU Configuration' menu and enable the virtualization option. Save the changes and exit BIOS to restart the computer.
Check the audio settings and ensure the correct playback device is selected. Verify that the speakers or headphones are properly connected. Update the audio drivers from the Lenovo Support site if necessary. Test with another audio device to rule out hardware issues.
