Re: I have an alienware 17 r2 battery charging don't work (plugged in, not charging) ?
Try doing a power drain. To do a power drain, follow the steps below.
Shut down the system, once it’s powered off, disconnect the AC adapter.
Disconnect the battery cable (refer to this video for disconnecting the battery cable, it shows how to disconnect the battery cable in the first 35 seconds).
Disconnect all external devices (USB devices, headsets, external monitors, etc.).
Press and hold the power button for 30 seconds.
Connect everything again and turn on the system.
If it is still doing the same thing, please send me a private message with your Service Tag, so we can look further into this.
