Diff between AW18s?

There are Alienware M18X-R1 : Alienware M18X-R2 : and Alienware 18 aka AW 18. AW 18 burns up a lot faster than the previous generations.

 

By "burns up" do you mean overheating or physical circuit frying? Is it descent enough or have I bought an un-repairable lemon? :-D

 

Alienware M18xR1 (2011) Sandy Bridge 2XXX series CPUs & 5XXM series GPUs (Come in Black & Red)
Alienware M8xR2 (2012) Ivy Bridge 3XXX CPUs & 6XXM GPUs (Come in Black & Red)
Alienware 18 R1 (2013) Haswell 4XXX CPUs & 7XXM, 8XXXM, & 9XXXM GPUs (Comes in Silver)

The 18 has motherboard issues due to bad mosfets being used.

 

Ah ok, what mosfets commonly die, do you know of some threads, pictures and more info of this issue? If that is a common issue it may be the same issue with the one I've bought.

When the mosfets die, do they just short out or do they burn the board?

Sorry for all the questions. :-D

 

I'm not sure, mine never died, but I did sell it.

@Raidriar had a couple die so maybe he can chime in.

 

Found this thread, hmm... nasty!

I wish I found this out before buying.

 

Is it the DC in mosfets or the GPU mosfets that are common faults?

 

Motherboard mosfets are the common killer, and they take the first gpu card with them.

 

I experienced the same failure as @imest on three different boards. When the third board failed, I parted out what was salvageable and chucked the husk into recycling bin. Piss poor excuse of a computer, Alienware should be ashamed they put it into production

 

@imest From those pictures they look to be the main DC IN mosfets, on these blowing up occasions did you have your AC adapters/chargers connected?
