Lenovo ThinkPad Edge E420 Power Adapter
The Lenovo ThinkPad Edge E420 AC adapter provides two functions, charging the battery and powering the laptop. When purchasing a replacement AC charger, selecting the Lenovo OEM charger is always going to be the safest and easiest way to go. Because Lenovo has been known to use a single AC adapter that is most likely used on other laptop models, make sure you check the part number for the correct one. If buying off-brand, make sure to check both the voltage and amperage output. A universal power adapter is a possibility but only if necessary.
Signals your laptop charger is failing
- The majority of Lenovo power chargers get warm when plugged in for 10 minutes or more
- The laptop does not operate without the battery installed
- Battery does not charge every time

Lenovo ThinkPad Edge E420 power adapter will be better for your laptop brand new because of wear and tear on any older used one.
