To connect dual monitors, ensure your ThinkCentre M90n-1 is equipped with the appropriate ports (such as HDMI and DisplayPort). Connect each monitor to a port on the computer. You may need to adjust display settings in the operating system to extend or duplicate the display.
First, verify that the power cable is securely connected to both the wall outlet and the computer. If the system still doesn't power on, try a different power outlet or cable. If issues persist, it may indicate a hardware problem, and contacting Lenovo support is recommended.
To perform a factory reset, restart the computer and press F11 during boot to access the recovery environment. Follow the on-screen instructions to reset the system to factory settings. Remember to back up important data before proceeding.
The Lenovo ThinkCentre M90n-1 is compatible with DDR4 SODIMM RAM. Check the specific model for maximum capacity and speed compatibility before purchasing additional memory.
Visit the Lenovo Support website, download the latest BIOS update for your M90n-1 model, and follow the provided instructions to update the BIOS. It's crucial to ensure the computer is plugged in and avoid interruptions during the update process.
Ensure that the computer has adequate ventilation and is placed on a hard, flat surface. Remove dust buildup from vents and fans using compressed air. Consider adjusting power settings to balance performance and cooling.
Restart the computer and enter the BIOS setup by pressing the necessary key (usually F1 or F2) during boot. Navigate to the CPU configuration section and enable the virtualization technology (VT-x or AMD-V) option. Save changes and exit.
The ThinkCentre M90n-1 is compact, and its expansion capabilities are limited. Check the specific model specifications to see if there are additional slots or consider using an external drive for additional storage.
Shut down and unplug the computer. Use a soft, lint-free cloth dampened with water or a mild cleaning solution to wipe down the exterior. Use compressed air to clean vents and ports, ensuring no moisture enters the system.
Upgrading the CPU in the M90n-1 is not typically recommended due to its compact design and potential warranty issues. If an upgrade is necessary, consult the service manual or a professional technician to ensure compatibility and proper installation.
