Dell Inspiron 5420 Power Adapter
When choosing a new charger, selecting the Dell OEM charger is always going to be the safest and easiest way to go. The Dell Inspiron 5420 AC adapter is responsible for two things, to charge up the main battery and to provide a source of power for the unit. If buying off-brand, make note of both the voltage and amperage output. Due to the fact that one Dell adapter is most likely used on other laptop models, be certain to thoroughly note the part number that is needed for this model. A universal power adapter is another possibility but only if necessary.
Important signs your AC adapter needs replacing ASAP
- Your Dell battery refuses to charge up at all
- Most Dell adapters will get warm to the touch when plugged in for 10 minutes or more
- The unit will not operate using just the AC power adapter
