Dell Precision M6400 Power Adapter
The Dell Precision M6400 AC adapter is needed for two reasons, to charge any and all batteries and to provide a source of power for the unit. If you decide to buy an non-Dell adapter, make note of both the voltage and amperage output. Due to the fact that one Dell adapter can be used on other units, make sure you check the part number for the correct one. When choosing a new AC adapter, selecting the Dell OEM charger is usually going to be the safest choice. A universal AC adapter is a possibility if yours is unavailable or backordered.
What warnings are present when my Dell power adapter is failing?
- The laptop does not function while just using AC power
- The majority of Dell power chargers will get very warm to the touch when plugged in for any length of time
- Battery does not charge all the time
