Dell Latitude 6420 Power Adapter
Because Dell has been known to use a single AC adapter that is probably used on other similar units, be certain to thoroughly note the part number that is needed for this model. If your decision is to purchase a different brand charger, please check on both the voltage and amperage output. The Dell Latitude 6420 AC adapter is needed for two reasons, to charge any and all batteries while simultaneously providing power for the laptop. Upon choosing a replacement AC adapter, the actual Dell brand is usually going to be the safest choice. A universal power adapter can be used but only if necessary.
Chief elements of a faulty power adapter
- Most Dell adapters can get quite warm when they are plugged in for a period of time
- The laptop does not operate without the battery installed
- Your Dell battery refuses to charge completely
