Lenovo ThinkPad A21M Power Adapter
If you decide to buy an non-Lenovo adapter, please check on both the voltage and amperage output. When choosing a new AC adapter, the actual Lenovo brand is usually going to be the safest choice. A universal AC adapter can be used if you are desperate. Due to the fact that one Lenovo adapter is most likely used on other laptop models, be certain you select the correct one for the ThinkPad A21M model. The Lenovo ThinkPad A21M AC adapter is responsible for two things, charging the battery and powering the laptop.
Simple warnings that your Lenovo power adapter is almost dead?
- Your Lenovo battery refuses to charge up whatsoever
- The majority of Lenovo power chargers get warm when plugged in for any length of time
- The unit will not operate using just the AC power adapter
