Lenovo B570E Power Adapter
If your decision is to purchase a different brand charger, please check on both the voltage and amperage output. Due to the fact that one Lenovo adapter is probably used on other similar units, be certain to thoroughly note the part number that is needed for this model. The Lenovo B570E power adapter provides two functions, charging the battery and powering the laptop. When purchasing a replacement AC adapter, selecting the Lenovo OEM charger is always going to be the safest and easiest way to go. A universal power adapter is a possibility if yours is unavailable or backordered.
Major signs your power adapter will die soon
- Most Lenovo adapters can get quite warm when they are plugged in for a period of time
- The unit will not work while solely using the AC adapter
- Your Lenovo battery refuses to charge every time
