Dell Latitude E5420M Power Adapter
Because Dell uses one power charger that is probably used on other similar units, be certain to thoroughly note the part number that is needed for this model. The Dell Latitude E5420M power adapter has two main uses, to charge up the main battery and powering the laptop. A universal AC adapter is a possibility but only if necessary. Upon choosing a replacement AC charger, choosing the Dell brand one is usually going to be the safest choice. If you decide to buy an non-Dell adapter, make note of both the volts and amps outputs.
Key clues of a poorly working laptop charger
- Battery does not charge every time
- The laptop does not work without the battery installed
- Most Dell adapters will get very warm to the touch when they are plugged in for a period of time
