Right before a project delivery, my Lenovo PC started rattling loudly. The PSU fan died. How early can you detect a Lenovo power supply that’s about to fail?
You can detect an impending Lenovo Power Supply (PSU) failure early by monitoring for unusual noises like rattling, grinding, or buzzing from the PSU fan—often the first sign of bearing wear. Other warnings include random crashes, blue screens, system freezes under load, overheating, or a burning smell. Regular dust cleaning and using tools like HWMonitor for voltage stability help catch issues sooner. For reliable replacements, check out Lenovo Power Supply options on 365powersupply.
