Is it alright if i plug my laptop while i am using it ?

Sparking is not good for your computer it is a great way to fry.if you want to switch from dc to ac 110V unplug the ADAPTER from the wall, plug in the cord to the laptop, THEN plug into the wall.(did you know static electricity from shuffling you feet can fry your computer.the spark from plugging in your laptop is 110V jumping to the nearest ground which happens to be your computer, and your computer runs on less than 12V.And never plug in 220V that is what your dryer or welder takes!
