Dell Inspiron 14R 7420 Power Adapter
When purchasing a replacement AC adapter, the actual Dell brand is always going to be the safest and easiest way to go. 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. A universal power adapter is a possibility but only if necessary. The Dell Inspiron 14R 7420 power adapter has two main uses, to charge up the main battery while simultaneously providing power for the laptop. If you decide to buy an non-Dell adapter, it is imperative to note the output of amps and voltage.
What to see if the Dell power adapter is in need of replacing?
- The unit will not operate while solely using the AC adapter
- Your Dell battery refuses to charge at all
- The majority of Dell power chargers will get very warm to the touch when they are plugged in for a period of time
