audioguru Posted November 23, 2010 Report Share Posted November 23, 2010 The old AC adapter will say on its label if its output is AC or DC, its output voltage and its max output current. It should say if the output voltage is regulated. It might show a picture of its connector and its polarity.Simply buy an AC adapter that has the same output voltage (AC, DC and if regulated), the same max output current or more and the same connector and polarity.Since you might not find all the details then buy a correct replacement from Dell.
