Lenovo Aptiva E 2274 Power Supply
Purchasing a new Lenovo Aptiva E 2274 PSU is quite simple as long as you have the old one for comparison. It is usually pretty easy to install a power supply in your Lenovo computer. The PSU, or power supply, is responsible for powering the different components that make up your Lenovo desktop. Never go too cheap on a PSU as it is the only thing between the outside power grid and your delicate internal Lenovo components. Try to replace a power supply with the same wattage or larger.
Clues to watch for to know your primary power supply has very little life left
- System shuts down while processing a taxing load
- The PC refuses to start
- You sense anything burning in the power supply
