Issues when plugging into AC power cord

Hi Mpinster,

     Understood. Glad you were able to clear that up. There isn't a specific order requirement for plugging in your power supply/charger so the symptom you describe that occurs when connecting to household current first should be considered an indication that something is GOING...not gone yet but going wrong with the power supply and it should be replaced at your very nearest opportunity. Power supply problems can be potentially catastrophic. Think of the power supply module as the only barrier between house current and your 19v DC laptop and you'll get a good idea of what that implies. Make sure you take down the Dell Adapter Family PA-xx number and simply order one from Dell, or find an OEM (Original Equipment Manufacturer...Dell) replacement from your favorite computer store or online site. Dell (and most other laptop Mfgs) use proprietary hardware allowing the power supply, computer and battery to "talk" to each other. I don't recommend taking a chance on a generic charger or a so called universal. Sometimes a house current without a dedicated ground (2 wire construction) will produce an electrical arch if the power supply is plugged into the wall without being connected to the laptop. That may be PART of your problem but there still should not be any symptoms beyond that.  If this answer was helpful please remember to hit the yes button and if you need further assistance please don't hesitate to contact.
