I've been having the same problem on a dell machine with similar specs.
After reflashing the BIOS with the latest firmware (A10) the hibernation crash was happening once every 5 trials aprox. I now found that disconnecting the ethernet cable before going into hibernation, and re-connecting it after coming out of hibernation seems to have solved the crash. I've been trying this for over a week with no crashes so far. Not entirely sure what this has to do with the crash (maybe related to the wake-from-lan option, although that is disabled in my machine), but if anybody else wants to give this a try it might be worth it.
I tried and still getting same issue with and without ethernet. Finally put it in for a refund and bought an alienware instead! Dell support were very helpful sorting out refund etc, but nobody could solve hibernation issue.
One tech did mention that it could be due to partitioning of the SSD, but I've had enough troubleshooting for a lifetime without starting to reformat my drive again!
we have the same problem with one of two XPS15z....
Dell Support said it's because incompability of some SSD drives.
The notebook with working hibernation has a 240GB Mushkin Chronos, it's also working with Intel Speedstep enabled.
And the other one with hibernation issues has a 480GB OCZ Agility3 and it's even not working with Speedstep disabled.
I have also tested a 256GB Samsung 830 which only works with disabled Speedstep.
Could some of you please tell me which SSD models are built into your XPS?
I have had three XPz - all the same problem
I have had two different Samgsung Models of Hard Disks-
I have come across 30 plus cases of this exact problem -
Do you know why Dell keep selling the machine. ?
I bough the machine for SSD hard Drive and high processing capabilities. Now I often Loose my work if when the resume fails or I run out of battery - This has cost me a 2-3times the price of the laptop.
Can you recommend reliable brand with similar specks?
I think they want to get rid of it in any way. In my eyes, this model is absolutely the biggest piece of crap that I've ever come over. The chrome strip goes off and has sharp edges, it's more difficult to disassembly than other models, it gets very hot and the wireless speed sucks. I wish my boss had chosen a different model emoticon.Devil.title
In our case, we bought the XPS with a normal HDD, on which hibernation works. But my boss needed a large 500GB SSD and so we bought it separately from a shop.
Because of this, Dell won't support us further. Anyway, Dell said that as business customer, we don't have the privilege to return something to get a refund (I think this is bullshit ^^) .
Now I'm trying to figure out which SSD are working and which do not.
But Dell told me, that they are now delivering with Crucial M4 SSDs. Maybe these are full compatible and even support Intel Speedstep. But who knows emoticon.Confused.title
Does it not work either when you turn off Intel Speedstep in BIOS? Or is the problem back after some time?
I went for alienware m14x - still dell, but works.
More pricey, but mine came with a free alienware monitor which I needed anyway, so pricing ended up similar.
Great machine, insanely fast.
Dell refunded my 15z and have let me keep it for a week overlap so I can transfer data across. Good service in that regard.
