Operation System Not Found
My wife has a Dell XPS-15Z laptop purchased in January 2012 with Windows 7 installed. Starting in the last couple days, when she wakes it out of sleep/hibernation, there is a black screen with "Operation System Not Found" in the upper left corner. Hitting escape causes Windows to open normally. It functions normally except that the fan is running pretty much all the time and the case feels hot to the touch around the hard drive and vents. When she reboots from a complete shut-down, both the error message and fan don't seem to reoccur.
The laptop is still in warranty, but we were wondering what may be causing this and what we may be looking at in terms of repairs.
Thank you.

Hi Pudgyone! I haven't had a chance - she's using it for work at the moment, But I should be able to today and will post the result. Thanks.

Yes, it is in warranty, but we're curious if there was a simple fix we could do at our end before going through the inconvenience of an exchange or repair. And yes, she's running it off the power line at home when the problems occur.
Curiously, when she rebooted, she did not get the error message and the fan has returned to normal. We'll see if there is a pattern. If there is, perhaps that's a clue that it has to do with the sleep/hibernation states.
Thanks.

Okay - I was able to run the diagnostic test. Everything passed. A couple of statistics:
- The battery charge was 100% across the board (Current, High, Low)
- The battery health was 99% across
- Processor fan (which ran the whole test) had a high of 5490 RPM and a low of 3200
- CPU thermistor high of 88 degrees C and a low of 66
- Ambient thermistor high 69, low 49
- Video thermistor high 70, low 49

Is there a diagnostic that would tell us if it's a software problem?
Thanks!

Ha! Too true!
So considering the error message, could it be a problem with the Windows 7 installation? Is there a way of checking that?
Thanks!

Still in warranty?
go to Dell Website, research the model and exchange if possible. Is it plugged in or running of the battery? Mine overheats and finally ran out my battery, so I took the battery out and just run it of the power line at home...however i assume you take it with you, so why mess around, get another one...my suggestion...
