I requested for the order cancellation for my desirable W520, after reading all the post regarding SSS.
it seems that even the latest intel chipsets manufactured at the end of 2011 have that problem.
I do travel lots, and I have already talked to renovo staff on the phone. All of them say they never (yeah i am pretty sure)
heard of such problem even at the technical department.
They rather suggested me not to cancel by offering futher discounts!

There's no way for us to know what percentage of W520's are affected by this issue, as the posts here aren't a representative sample. It might only be 1 in 10,000. Also, many people who post on here claiming the sudden shutdowns haven't contacted Lenovo about it. So I wouldn't be too surprised if many people at Lenovo don't know about this problem. Having said that, there are definitely people having this problem and Lenovo isn't (or can't) really doing anything about it. I knew about this issue when I bought mine several months ago and went ahead anyways, and I've had no problems.

Well if Lenovo is so confident in the W520, they could always offer a free 3 year warranty to assure customers. It's not like they have offered any tangible information on SSS.

The pre-built systems come with a 3 year warranty.
I forgot they did. That certainly removes some of the worry. I am hopeful to have a W530 before year end.

I think the W520 is pretty solid and stable...
What I can't comment on is how it compares to the other mobile workstations on the market.
As far as this SSS goes...it happened to me twice in one day, within the past 2 weeks. In my case, it seems like it has something to do with the following conditions combined:
1. System in sleep mode.
2. System went into sleep mode with the Logitech wireless receiver plugged into the back / powered USB port.
3. A fully charged 27++ was also connected and locked in throughout the duration of the sleep, even before entering into the sleep.
4. Power adapter connection did not matter.
5. The Logitech wireless receiver was unplugged from the system while the system was in sleep mode.
6. SSS didn't happen immediately.
7. SSS would occur sometime between Point 5's event, and manually opening the lid. (This period was 1 hour for the the first occurrence, and 7 hours for the second occurrence).
Other than this, I like the system a lot. Fast, stable, reliable.
Mine also came with the 3 year return to base warranty by default. (Lenovo then transferred the old upgraded warranty to this system, from my old, returned, W510).

Your scenario does not sound like SSS, but rather a Windows driver issue. The unplugging of the Logitech receiver most likely awakend the system which then may have blue screened and restarted. SSS is a symptom exhibited by the system at idle either on AC or battery. No other external stimulus is required. There have now been some reports of static electricity possibily contributing to the issue, but this again is an external stimulus and is most likely unrelated to the SSS events.

Hi harrisb, I verified that BSOD was not the case. There was no BSOD minidump...even when memdump was enabled.
Nor did the system wake up when I unplug the logitech wireless reciever from the powered USB port. It remained in suspend mode for quite some time, which is why I wasn't able to pin point when the SSS happened exactly after I pulled the reciever.

OK, still curious as this is a totally different scenario than any which have been reported to date. Thanks for the response.

I'm trying to replicate the issue...but have not been able to.
Two things I've changed since the two SSS happened:
1. Updated the Intel RST driver. (I doubt it's the driver, because typically, driver issues are caught by Windows...hence BSOD).
2. Swapped out the original Toshiba 120GB SSD that came stock with the laptop, and replaced with an Intel SSD.
Still trying to replicate the SSS...
And when I can, I'll post my system's hardware and software config.
