Dell Vostro 14 3449 Power Adapter
Because Dell uses one power charger that powers multiple other machines, make sure you check the part number for the correct one. The Dell Vostro 14 3449 AC adapter is needed for two reasons, to charge the onboard battery and powering the laptop. A universal AC adapter is another possibility if you are desperate. If buying off-brand, please check on both the voltage and amperage output. When choosing a new adapter, the actual Dell brand is the best one to choose.
Major warnings of a worsening AC adapter
- Most Dell AC adapters will get very warm to the touch when plugged in for 10 minutes or more
- The unit will not work while just using AC power
- Battery does not charge up all the time
