Dell Latitude E7440 Power Adapter
When purchasing a replacement AC adapter, the actual Dell brand will probably be the safest way to go. The Dell Latitude E7440 power adapter is responsible for two things, to charge any and all batteries and powering the laptop. Because Dell has been known to use a single AC adapter that powers multiple other machines, be sure you choose the right one. A universal power adapter is another possibility if yours is unavailable or backordered. If your decision is to purchase a different brand charger, make sure to check both the volts and amps outputs.
Major warnings of a bad laptop charger
- Your Dell battery refuses to charge all the time
- Most Dell adapters will get very warm to the touch when plugged in for any length of time
- The laptop does not work while just using AC power
