Dell Latitude E5420 Power Adapter
Because Dell uses one power charger that powers multiple other machines, double-check the part number or model number of the adapter. If you decide to buy an non-Dell adapter, make sure to check both the volts and amps outputs. When purchasing a replacement adapter, the actual Dell brand is always going to be the safest and easiest way to go. The Dell Latitude E5420 power adapter is needed for two reasons, charging the battery and to provide a source of power for the unit. A universal power adapter can be used if yours is unavailable or backordered.
Easy warnings your AC adapter is on its last leg
- Battery does not charge completely
- The majority of Dell power chargers will get warm to the touch when they are plugged in for a period of time
- The unit will not run while solely using the AC adapter
