First, ensure that the power cable is securely connected to both the computer and the power outlet. Check for any visible damage to the cable. If everything looks fine, try a different power outlet or replace the power cable. If the issue persists, the power supply unit (PSU) may need to be checked or replaced.

Close the case and reconnect all cables before powering on the computer.
To clean the fan, first turn off the computer and unplug all cables. Open the case to access the internal components. Use a can of compressed air to blow dust out of the fan blades and surrounding areas. Be careful not to tilt the can to prevent moisture from escaping.

Several factors could cause your Lenovo ThinkCentre M725s to run slowly. Check for viruses or malware using a reputable antivirus program. Ensure that the system is not running low on RAM by closing unnecessary applications. Consider upgrading the RAM or switching to an SSD for faster performance. Regularly clean up unnecessary files and defragment the hard drive if it's not an SSD.
