First, ensure that the power cord is securely connected to both the computer and the power outlet. Check for any damage to the power cord. If the issue persists, try a different power outlet or use a multimeter to check the power supply. If none of these work, it may require professional repair.
To upgrade the RAM on your Lenovo IdeaCentre AIO B750, first ensure the computer is powered off and unplugged. Remove the back panel by unscrewing it, locate the RAM slots, and carefully insert the new RAM module, ensuring it clicks into place. Reattach the back panel before powering on the device.
Your Lenovo IdeaCentre AIO B750 may be slow due to background applications, insufficient RAM, or malware. Try closing unnecessary programs, upgrading your RAM, and running a full system antivirus scan. Additionally, check for and install any available updates for your system.
Screen flickering can be caused by outdated display drivers or incorrect refresh rate settings. Update your display drivers via Device Manager and ensure the refresh rate is set correctly in the display settings. If the problem continues, the screen may require professional inspection.
