    Mostly it’s power jack issue. one of dc jack legs which connected on motherboard to controller which detects Ac Adapter is broken or loose. In that case you will need to replace dc jack.nSometimes you can use ac adapter with higher wattage. it may be temporary solution. but best go to tech, and replace dc jack.

  2. its the data cable in the power cord that has broken , most of the cases happens right by the jack that plugs into the dell, the silicon in that plastic mould around the jack hardens and cracks causing the britel red middle data cable to brake hence copmuter no longer recoginse it
