Re: No screen after resume from Sleep, XPS 12 9Q33

I do have the irst application installed. Was waiting for a proper workaround and thanks Dell for the fast turnaround on the bios update. But I think in disabling by the bios, it broke irst in a way. The application used to launch when the bios setting was disabled, just not configurable in the application settings. After general use I started to notice the popup

saying irst is disabled and the irst applications will not launch. I didn't check if the irst bios setting was grayed out prior to the A02 update. I noticed the bios setting when trying enable irst again. There is the help tip in the bios, F1 help, that says the three status changes where irst will be disabled by the bios. But I think I did not intentionally meet those changes like removing the 8gb partition.

I hope the solution is not format and wipe to get IRST back and functional, that would a be a bridge to far.

In the bios after updating to A02, under the advanced tab, what is the settings for SATA operation do you have more than one option (AHCI)?

I installed the new bios (A02), (turned off irst with the software since it was causing the no wake from sleep issue) I re turned on irst with the software. rebooted. put the computer to sleep, tried to bring it out of sleep, no luck. same problem

What OS are you all using? If Windows 8....try disabling Fast Boot.

Re: No screen after resume from Sleep, XPS 12 9Q33

Hi Terry B ... wondered if you have other suggestions. A Dell engineer is coming on Monday for something unrelated ... are there any diagnostics etc that they can do that would be helpful?

Thanks.

I have been checking with engineering.  It could well be that after flashing to A02 IRST is meant to be disabled.  This is further implied that the only option for SATA Options is AHCI.

I hope to have information verifying this or not at the start of next week.

How happy I am to find I'm not alone :)

I'm now going to try the BIOS upgrade (had to actually open the "My Dell" application to be alerted for it) and we'll report shortly if it fixed it or not
