Samsung NP740U3E Power Adapter
Due to the fact that one Samsung adapter can be used on other units, make sure you check the part number for the correct one. The Samsung NP740U3E power adapter provides two functions, charging the battery while simultaneously providing power for the laptop. A universal AC adapter is a possibility if you are desperate. Upon choosing a replacement charger, selecting the Samsung OEM charger will probably be the safest way to go. If your decision is to purchase a different brand charger, make note of the output of amps and voltage.
General warnings of an ailing AC adapter
- The unit will not operate while just using AC power
- Battery does not charge up all the time
- The majority of Samsung power chargers get warm when plugged in for 10 minutes or more
