I have an M11x from 2010 which has worked fine except that it powers off as soon as you unplug the AC adapter (even though the battery shows a 100% charge).
Today I tried removing the battery and then held the power button for 30 secs, then replaced the battery. Then I plugged the computer in and turned it on again. The Alienware logo and keyboard both light up (and remain lit even if I pull the AC cord), but nothing appears on the screen.
What's going on? Are these related issues? And where can I get replacement parts? It seems as if they are hard to find for this computer already.
