Dell Latitude E6540 Power Adapter
Because Dell uses one power charger that is probably used on other similar units, double-check the part number or model number of the adapter. The Dell Latitude E6540 power adapter is responsible for two things, to charge the onboard battery and to provide a source of power for the unit. A universal power adapter can be used if yours is unavailable or backordered. If you decide to buy an non-Dell adapter, make sure to check both the voltage and amperage output. When choosing a new adapter, selecting the Dell OEM charger is usually going to be the safest choice.
What to see if the charger is about to fail?
- Most Dell AC adapters will get very warm to the touch when they are plugged in for a period of time
- Battery does not charge up at all
- The laptop does not function using just the AC power adapter
