Lenovo ThinkCentre 9142 Power Supply
It is usually pretty easy to install a power supply in your Lenovo computer. The PSU, or power supply, supplies all the power for the hard drive, motherboard and any other peripherals in the PC. Purchasing a new Lenovo ThinkCentre 9142 PSU can be a breeze, especially if you still have the old PSU to measure, size-wise. Never go with the cheapest power supply because it is the only barrier between a large quantity of electricity and fragile internal computer components. It is always a good idea to replace a power supply with the same size or bigger.
Major symptoms of a weak main power source
- Your desktop is unable to start
- Your Lenovo turns off while under a heavy load
- You notice anything burning in the power supply
