Dell PP21L Power Adapter
When purchasing a replacement charger, choosing the Dell brand one is always going to be the safest and easiest way to go. Due to the fact that one Dell adapter is most likely used on other laptop models, be certain you select the correct one for the PP21L model. The Dell PP21L power adapter provides two functions, to charge any and all batteries and to provide a source of power for the unit. A universal AC adapter is a possibility if you absolutely need to. If you decide to buy an non-Dell adapter, make sure to check both the volts and amps outputs.
Major warnings of a faulty charger
- Battery does not charge all the time
- Most Dell adapters can get quite warm when they are plugged in for a period of time
- The laptop does not operate while solely using the AC adapter
