Lenovo ThinkPad E450 Power Adapter
When choosing a new AC adapter, selecting the Lenovo OEM charger is always going to be the safest and easiest way to go. Because Lenovo uses one power charger that is probably used on other similar units, be certain to thoroughly note the part number that is needed for this model. The Lenovo ThinkPad E450 AC adapter provides two functions, charging the battery and to provide a source of power for the unit. If you decide to buy an non-Lenovo adapter, please check on the output of amps and voltage. A universal AC adapter is a possibility if you absolutely need to.
Easy warnings of a dying AC adapter
- Most Lenovo AC adapters can get quite warm when plugged in for any length of time
- Your Lenovo battery refuses to charge up all the time
- The laptop does not run using just the AC power adapter
