Dell Inspiron M5040 Power Adapter
The Dell Inspiron M5040 AC adapter is needed for two reasons, to charge the onboard battery and powering the laptop. If your decision is to purchase a different brand charger, please check on both the volts and amps outputs. Because Dell has been known to use a single AC adapter that is most likely used on other laptop models, be certain to thoroughly note the part number that is needed for this model. A universal AC adapter is a possibility but only if necessary. When choosing a new adapter, choosing the Dell brand one is usually going to be the safest choice.
