Hi theli66,

I sincerely regret any difficulty you have experienced with the new computer.

To isolate the issue let’s try few more troubleshooting steps.

Check with a different wall outlet. Connect the computer to a different wall jack and see if the same issue persists.

I recommend you to remove the battery and disconnect the adapter, press and hold the power button for few seconds and release to drain the flea power .Now put back the battery and connect the adapter and power on the computer and check if the adapter works.

If the issue still persists, disconnect the battery and just connect the adapter to the computer and check if the computer works continuously on adapter.

Another step is to check with a known good adapter, if known good adapter works fine that means it should be an issue with the original adapter.

Awaiting your response!

Thanks for the reply

I checked the AC adapter in 6 other power outlets and still doesn´t work. I turned on the laptop and it works fine with the battery, then connected the adapter to it but the computer keeps working with the battery and doesn´t register that the adapter is plugged in. I followed the recomendation to  drain the flea power but there was no change.

The blue light at the end of the adapter cable that turns on when the adaptor is plugged to a power outlet doesn't turn on.

The adapter needs to be replaced - call Alienware for a warranty replacement.
