Hello i Have Alienware M17x R3 and it recently starting to break down :(
when i plug it in , battery is not charging and performance is really low.
when i unplug it it runs fine as long i have it running on battery.
I have tried this:
1. close laptop and remove battery (while still on).
2. open lid and remove AC adapter (while still on, will power off system)
3. close lid and connect battery
4. open lid, connect AC adapter, and power on.
but did not help
