Dell Inspiron 14 M4040 Power Adapter
Upon choosing a replacement charger, selecting the Dell OEM charger will probably be the safest way to go. Because Dell uses one power charger that powers multiple other machines, make sure you check the part number for the correct one. If your decision is to purchase a different brand charger, make sure to check both the volts and amps outputs. A universal AC adapter is another possibility if you absolutely need to. The Dell Inspiron 14 M4040 power adapter provides two functions, to charge up the main battery and powering the laptop.
Major symptoms the power charger needs replacing ASAP
- The laptop does not work using just the AC power adapter
- Battery does not charge completely
- The majority of Dell power chargers get warm when plugged in for 10 minutes or more
