Re: Helix 20CG won't wake from sleep mode

2016-08-23, 14:30 PM

Not sure why Intel graphics drain too much energy (at least not on my device)

But for Realtek USB Audio (USB\VID_0BDA&PID_4000&REV_0002&MI_00), it is because Realtek USB Audio driver doesn't support sleep. In windows 8, this device is using the default system driver (published by Microsoft), but in Windows 10, the system will automatically update the device driver to the one published by Realtek (6.3.9600.14 if I remembered correctly). I tried newer USB audio driver (6.3.9600.50) but still didn't help. The only work around is to use windows default driver (14393), by uninstalling realtek driver in the device manager first, waiting until system automatically update it to realtek driver (usually several seconds after the system re-recognize the USB audio device), and then choosing "roll back driver" so that the system will not update the USB audio driver any more. The drain has changed from 2000mw to ~1000mw after using system default driver, which is normal when helix is docked

 

To forum moderator: if you are keeping track of this thread, please let lenovo know that the new 1.87 BIOS still doesn't fix the "open lid action" setting. I am not sure if there is a better way to give a feedback to lenovo, but it seems all my bug reports on this forum are ignored by Lenovo. I'm very disappointed

Out of scope for this thread maybe, but your tips for uninstalling and roll back the audio driver was fantastic xRender. Went to bead with just 6% left in my batteries and woke up (7 hours later) with 4% and 16 minutes of working time. No sleeptime registered in "powercfg /sleepstudy" though, but maybe that's ok. Thanks a lot xRender

Glad to see my workaround helps. Hopefully Realtek can provide a better driver in the future....

Still having problem with waking up from sleep mode though. Or waking up might not be correct, since the PC wakes up (can see the red LED and can hear beeps when pushing e.g. the shift key a lot of times), but it sometimes does not start the integrated display. Two applications that I can connect to this behaivour is Citrix GoToMeeting and Microsoft own Power BI Desktop

Anyone else that can confirm this?

I don't have GoToMeeting or the Power BI installed and I still encounter issues with the screen not coming on during wake, but not if I put it to sleep by pressing the power button, but rather only when close the physical setup first, detatching the screen and placing it over the keyboard.   This is after ensuring I had the upgraded BIOS, after I rebuilt the PC with the latest windows 10 build two weeks ago, and after updating all of my drivers to the recommended levels from this discussion.

 

I will note that after the Windows automatic patches last week my Helix 20CG crashes with Windows 10 BSOD frequently and with multiple different error messages, not the same one every time.  So, now I can't go through the day without at least 3 crashes.  Frustrating.

That's basically it. If you play some music and then put the machine to sleep, you'll hear the music still playing when you try to wake it. The screen just won't turn on.

 

I tried to make sure everything was up to date, including manually upgrading DPTF from extracted cabs. With everything as updated as I could make it, it still wouldn't work. Then I installed the old 4279 graphics drivers and just like that, resume works.

Installed Windows 10 anniversary update some two week ago. Since then seems to be ok (using hibernation). BIOS 1.87.

When it occurs it seems a bit different from Helix2 to Helix2. What most concur it is when the lid is closed and it goes in either Hybernation or Standby. Have you test it with the lid close and then waking it up by opening the lid or other means?

Where do you get the 4279 graphics drivers? By uninstalling my 4483 I just get the "Microsoft basic display adapter" and the Helix2 does not recognice now anything else unless I install Intel drivers.
