Re: Flex 6-14ARR downgrade BIOS

2019-08-22, 16:49 PM

 

 

Here's an image from my Device Manager. I'm not sure where to go from here to do what you're suggesting. 

 

Edit: Apologies! I didn't notice the option to install from a device until just now. I went through the warning messages and installed it, and the Yoga Mode Control Device seems to be showing twice now. Will let you know if it's worked.

Follow the order:

After you're done with that, it should show the Lenovo Yoga Mode Control Device twice in the list, but after doing that, the standby worked for me again.

Thanks for the instructions. I went through and tried it, but it doesn't seem to have worked. When I close the laptop, it still freezes.It is pretty terrible that Lenovo can't come out with something to fix something fairly crucial.

In that case my Yoga 530 apparently is some kind of special snowflake :smileyvery-happy:

I mean, we tried a lot already to get it working and nothing does. After all, standby is an essential function. Their latest audio driver also didn't fix the 2 second playback delay over the headphone jack, and neither did the driver for the WiFi fix the constant WiFi connectivity issues. That gives me really little hope that they will eventually fix this. There also isn't any difference between the BIOS versions 45 and 52.

Perhaps you already having the latest audio drivers for AMD Audio CoProcessor is the reason your fix worked. I'll update that driver once again, restart, and update this post on whether it works or not.

 

Update: Didn't work. Current status of device:

  • Windows 10 64x on update 1803; BIOS 8mcn52ww
  • AMD Audio CoProcessor running latest driver
  • Lenovo ACPI-Compliant Virtal Power Controller running Lenovo Yoga Mode Control Device
  • Standby still does not work.

Yup, it's an absolute nightmare. My version, according to the latest version on the Microsoft Update Catalog, is not the latest version as I never actually upgraded the driver for the AMD Audio CoProcessor. What I found to be definitely working is going to the advanced configuration of the current power plan and enabling the Hybrid Standby mode.

 

Edit: What is your driver version of the AMD Audio CoProcessor and both of the Yoga Mode Control devices? Because I just tried it and it works even without enabling the Hybrid Standby (which it didn't before).

 

Edit 2: I seem to be having the magic device. I promptly re-installed Lenovos latest Energy Management Driver (version ends with number 189, you can download it off the Lenovo webpage), and suddenly it works with that. It sure takes its sweet time (maximum 30 seconds) to actually enter standby, but it never fails to enter or exit standby anymore somehow. I tried that driver version before, and it constantly crashed, so I am not certain if the driver fixed it or if we needed specifically the version 189 instead of the version 187 and 188 with the new BIOS.

Ah, okay. Because my Yoga Mode Control driver is, interestingly, on version 3.0.0.even though the latest version is 3.0.0.6 (but Lenovo still doesn't want it updated), while my AMD Audio CoProcessor is version 1.15.0.83 from the 22nd of April 2019. I didn't touch either the Yoga Mode Control or the AMD Audio CoProcessor driver, so I don't know how that happened. Maybe it found some magic pill or something, I don't know. You could also try these exact drivers if you find them because the Flex 6-14ARR and the Yoga 530 are literally the same device.

Re: Flex 6-14ARR downgrade BIOS

I'll go ahead and try to match up my versions with yours. Just for posterity's sake, could you list out the devices with the changed drivers, as well as your version of windows, and what BIOS you're using?

 

Edit: Also, is that version correct for both of your Yoga Mode Control Devices?

 

Edit 2: This whole issue might be because my device is currently on Windows 10 1803, whereas most of the driver updates you've mentioned are for Windows 10 1809. May just be a bug with the version I'm using, could be fixed by updating to 1903.

Like I told you, I downloaded the Energy Management Driver from Lenovo with version 189, and that restores its drivers to (in my case) 3.0.0.5 and installs the Energy Management Driver with version 15.11.28.189 over the second, not actual Yoga Mode Control Device. I have them separate again. The drivers are as listed. Audio (yes, disabling that fixes the issue as the audio driver is also linked to the AMD Audio CoProcessor) is 6.0.8703.1

AMD Audio CoProcessor is 1.15.0.83

Yoga Control Mode Device is 3.0.0.5 (yes, that has been automatically installed upon installing the Energy Management Driver as the Yoga Control Mode Device driver is part of the Energy Management Driver) and that's it. I also don't know why it works all of a sudden.

The BIOS version is, like yours, 8MCN52WW.
