bentouch Posted November 10, 2013 Share Posted November 10, 2013 I just found a serious problem with my M18x.When ever i turn the SLI on and start to play for eg. Battlefield 4 (so it starts to use boths cards) my power brick just turns off!So it seems like by GPU(2) has some fault or whatever, that turns the brick off.Anyone knows what might be wrong?@EDITJust the same thing happened - without SLI ON!So or my power brick could be broken or the GPU(1).Could it be because of some power problems at the house? Or it's definitely hardware problem? Any ideas? Quote Link to comment Share on other sites More sharing options...
southpole560 Posted May 17, 2014 Share Posted May 17, 2014 It sounded like at first your laptop was drawing too much power that the powerbrick could handle but then you said that it happened when you just used one of your cards. It seems possible that it could be a faulty powerbrick. Quote Link to comment Share on other sites More sharing options...
Digimortal Posted May 24, 2014 Share Posted May 24, 2014 Sound like the switch mode supply in the power brick is having issues, as mentioned by southpole try seeking a replacement. Quote Link to comment Share on other sites More sharing options...
madman404 Posted June 11, 2014 Share Posted June 11, 2014 Something sounds up with your power brick, I think that's probably the issue. Quote Link to comment Share on other sites More sharing options...
Quang Khoi Thai Posted June 19, 2014 Share Posted June 19, 2014 I encountered quite similar problem on my old M17X R4 as yours. The machine turned off suddenly sometimes without a sign. Then I found that the graphic card caused a short-circuit; and that's why the power brick turned off automatically (to protect to system). I removed the graphic card and used Intel HD graphics instead, then machine worked well again.Thus, I think that your problem comes from the discrete graphic cards.

adam222 Posted June 27, 2014 Share Posted June 27, 2014 My alienware broke some time ago (m18x r2) and i still got the powersupply. Maybe you are interested? Quote Link to comment Share on other sites More sharing options...
Guest Posted June 28, 2014 Share Posted June 28, 2014 My alienware broke some time ago (m18x r2) and i still got the powersupply. Maybe you are interested?If you still have the broken M18xR2 I may be interested in buying it as a source for spare parts. Let me know if you still have it and want to sell it.

LiegeKiller Posted July 7, 2014 Share Posted July 7, 2014 Did you ever figure out the cause of this?I've a 6990m Crossfire setup and I think I might have a similar issue.Sometimes when I've started the machine up I notice I'm getting awful performance - it's usually because I'm not in Crossfire mode because the power brick is off.Now, it might be because I didn't plug it in properly in the first place, :-), but sometimes I'm sure it was on.
