Lenovo ThinkPad 720 Power Adapter
Because Lenovo has been known to use a single AC adapter that powers multiple other machines, be certain you select the correct one for the ThinkPad 720 model. If your decision is to purchase a different brand charger, make note of both the volts and amps outputs. A universal AC adapter is a possibility if you are desperate. The Lenovo ThinkPad 720 AC adapter has two main uses, to charge up the main battery and powering the laptop. When choosing a new adapter, selecting the Lenovo OEM charger is the best one to choose.
Key signs of a worsening Lenovo power adapter
- Your Lenovo battery refuses to charge up completely
- Most Lenovo AC adapters can get quite warm when they are plugged in for a period of time
- The laptop does not function while solely using the AC adapter
