Dell P20G Power Adapter
If you decide to buy an non-Dell adapter, make note of both the voltage and amperage output. The Dell P20G power adapter is responsible for two things, to charge up the main battery and to provide a source of power for the unit. Upon choosing a replacement AC adapter, selecting the Dell OEM charger is the best one to choose. A universal power adapter is another possibility if you absolutely need to. Because Dell uses one power charger that is most likely used on other laptop models, double-check the part number or model number of the adapter.
Clues your power adapter has little time left
- The laptop does not operate using just the AC power adapter
- The majority of Dell power chargers can get quite warm when plugged in for any length of time
- Battery does not charge every time
