    Hi guys,

    Got a 15 r2 just came in with a faulty burnt out DC jack socket, now i have done some research and the findings seem conflicting so im wondering if somebody can definitively clear this up please.

    Will a simple DC Jack replacement fix this ? or is it a complete mobo replacement job?

    Would appreciate some guidance as i will be sending the system back if it's a motherboard replacement too, don't mind replacing the DC Jack on its own if its a 100% fix.

    Somebody did mention there was a batch of a faulty dc sockets but i can't find any threads or statements from Dell.
    @DeeX @iunlock are you guys aware of anything i know you are close to Alienware directly?

    Cheers in advance :)

    I can not think of a way to know until you buy a replacement DC jack. DC jacks are super cheap and take around 7 days shipping time.

    for dc burnt.. update your bios at least to bios 1.3.12.. they have fix that issue through bios update.. @rinneh can pitch in for this.. Best route is if you are in warranty ask dell to fix it for you.. If not buy a dc cable first then try to roll out the issue.. if it doesnt fix it.. might be mobo problem that got damage.. again if you have fixed it by buying a new dc cable then update to the most recent bios if possible..

    Thanks for the replies guys, i can replace the DC no problem at all and have one on order as we speak.

    Just worried that its the mobo that's the cause more than the DC sockets, are we of the opinion then replace DC Socket + disable express charging + bios update will stop the burn out when new cables installed?

    Yeah in general that should be sufficient, but also dont overclock or else you still pull too much power maybe if you are unlcuky. Just check the motherboard, if you dont see visible damage, there pretty much is none.

    Partly yes, on pre 1.12 bioses ther was express charging enabled by default and some other issues. The latest bioses should have fixed this. I didnt had this issue with my aw15r2 for a long time after updating but after 2 years it came back. Might be because of a slight overclock. Pretty much the archilles heel of the aw15r1 and r2. Too thin dc in cables. The new models have way better dc in cables.

    Okay that's a positive thank you, appreciate your time.

    I will be LM the CPU / GPU, the GPU is a 980M but the CPU is only a 6700, so not tooo much draw from the CPU side.

    after replacing my DC jack, the laptop performance is better, the heat that come from that zone (near to ram) is a lot less.
    @cope123abc also a good thing is that now i can play with the 180Watts adapter, something that new i cant witout battery draining or throttling

    Its nto the heat itself that was the problem. But a too high current pull from the laptop in combination with too thin cables unfortunately. In normal circumstances you should be good with a newer revision cable (they made revisions of this), no express charging and no overclocking of the GPU. A slight overclock can add 30watts easily for example.
