Lenovo A740 Power Supply
Try to replace a PSU with at least the same watts, if not bigger. You will not want to cut corners when buying a power supply because it is an important barrier between the power coming from your wall and delicate components inside your Lenovo. The PSU, or power supply, is in charge of distributing power to the hard drive, motherboard and any other peripherals in the PC. It is not too difficult to install a power supply in the A740 desktop. Purchasing a new Lenovo A740 PSU can be a breeze, especially if you still have the old PSU to make a size comparison to.
Major symptoms of an ailing main power source
- You smell anything burning in the PSU
- System shuts down while processing a certain amount of stress
- The Lenovo refuses to power on
