Tips for how to choose the right power adapter/charger for your laptop:

1.  Please make sure the power adapter's Output & Connector Size are matching your original Adapter's.
   
2.  Output Voltage and polarity must match with your old adapter.
3.  Output Current is not as critical as output voltage, you could select either same or higher output current adapter.
4.  If the previous three notes are the same as your adapter, you can be sure our adapter is compatible, even if your model is not listed.
5. You can check with the Output Voltage and Output Current on the label of your original charger or the bottom/back of your laptop. As to the polarity (connector size) you can measure it or compare with ours.
