Re: Hey Lenovo, what's up with DPTF & Yoga machines?

Disabling the DPTF is not a solution

 

@Lenovo: Fix this issue! Tablet/Stand-Mode is useless with this issue and this is the reason why you buy a Yoga-Product.

Hello,

 

I had the same problem, so I disabled DPTF in the BIOS, and the problem of slow "non-tablet" modes is now solved.

 

BUT I can still see the CPU throttling (with CPUId), in all modes, just like it's suposed to do to save power !

 

Windows 10 is managing the throttling by itself (in Advanced Power Settings of a Power Plan, in Power Options). The name of the option is: Processor power management.

 

Those complaining, have you checked like I did with CPUId to see if CPU throttling is still active, after disabling it in the BIOS ?

 

(I have a Yoga 2 11 with the latest BIOS and drivers.)

I just updated Windows 10 with the fall update (1511 build 10586.29), and I am getting CPU throttling again despite the KonaDPTF9w.bat fix that I had done in September when I first updated to Windows 10, that had enabled me to use the stand mode which is my normal mode.  Has anybody else encountered this?  Any solutions other than to disable the DPTF?

I had to re-run the fix after updating with the big Windows 10 update in November. I re-tested the CPU performance in tent mode, tablet mode and with a second screen attached and it worked fine once again after the batch file was re-applied.  Don't forget to reboot the laptop after running the Kona batch file.

And aha, that solves the problem.  Rerun the file, reboot the system.

Hello Everyone,

 

If people havent already figured this out, i have found a good fix for this issue. I too was having an extreme slow down when in tablet mode in Window 10. I read about the bios fix, and didnt feel comfortable disabling Dptf. I also didnt feel comfortable changing the .Bat file of older drivers. I found an easy fix.

 

  1. Right Click - StartMenu > Device Manager
  2. Open up System Devices
  3. There are 3 DPTF Devices Example"Intel Dynamic Platform and Thermal Framework......
  4. Right click each one and update driver
  5. Select the search automatically for updated driver software.... it downloaded a new one online
  6. For me it found newer drivers than what is available on lenovos website. v: 8.1.10605.221 Driver date 10/23/2015
  7. It moved all 3 devices out of System Devices into there own section.
  8. I dont remember restarting but it wont hurt. And now everything is silky smooth in tablet mode. So im taking it that windows has access to newer intel drivers than lenovo is giving us.

This works like a charm. When I upgraded to Windows 10 last year - I followed the old batch file option.

 

But this time I did exactly as mentioned here and updated drivers via device manager and my laptop is back to normal.

 

Many Thanks and hope it helps others too.
