Dell PP28L Power Adapter
If your decision is to purchase a different brand charger, please check on both the volts and amps outputs. Upon choosing a replacement AC adapter, the actual Dell brand is always going to be the safest and easiest way to go. A universal AC adapter is a possibility but only if necessary. Because Dell uses one power charger that is most likely used on other laptop models, make sure you check the part number for the correct one. The Dell PP28L AC adapter provides two functions, to charge the onboard battery and to provide a source of power for the unit.
Signals your AC adapter will die soon
- The unit will not operate while just using AC power
- Battery does not charge up at all
- Most Dell adapters will get warm to the touch when plugged in for any length of time
