Dell Latitude C540 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. If buying off-brand, make note of both the volts and amps outputs. The Dell Latitude C540 power adapter is needed for two reasons, charging the battery and powering the laptop. When purchasing a replacement AC charger, the actual Dell brand is usually going to be the safest choice. A universal AC adapter is a possibility if yours is unavailable or backordered.
Symptoms of an unhealthy AC adapter
- Most Dell adapters can get quite warm when plugged in for any length of time
- The unit will not function without the battery installed
- Your Dell battery refuses to charge up every time
