Windows 10 and DPTF

Was having all kinds of issues with Win 10. Disabling DPTF seems to have solved most of them, particularly the sluggish ressponse times (programs that took 2-3 seconds to open under 8.1 were taking 1-2 minutes under 10). Not sure why disabling DPTF seems to cure all these issues, or what the downsides might be. Any ideas? Thanks!

 

Incidentally, all the useful tech support I've received on the Win 10 upgrade came from Plugable. Lenovo has been worthless.

TBH, if you don't need anything DPTF offers, get rid of it.

Re: Windows 10 and DPTF

AFAIK, it changes the CPU performance profile based on the mode of the laptop. More often than not, it decides to limit the CPU speed.

That might be ok, but under Win 10 it's throttling even in normal laptop mode.

Re: Windows 10 and DPTF

Excuse my ignorance, but what is DPTF and how do I remove it?
I am asking this because I may switch to Win 10 soon and I already find the Y3P slow enough for my liking...I don't need more slowness :-)

Re: Windows 10 and DPTF

In easy words: DPTF is taking care of your hardware and prevents overheating by throttling the CPU e.g. in tablet mode. You can best disable it in BIOS.

Re: Windows 10 and DPTF

Hey, been running Windows 10 with all the latest drivers. The Windows 10 traditional desktop in "Yoga laptop mode" worked great, but the laptop and Chrome were unusable under 'Yoga tablet mode'. SOLUTION:  Make sure you disable DPTF in the BIOS, as that fixed all performance issues for me. I had actually had issues with this setting before and had disabled it, but at some point I updated the BIOS and the options was enabled agian by default.  I highly recommend this.  I use Chrome and Google to manage my life and business.  Anything other than "laptop mode" was useless.  Once I disabled the DPTF setting in the BIOS, viola!!  All problems solved and changing modes works better than ever!!!!!!  To boot into BIOS, power down the yoga 2 pro.  Looking at the right side power button, notice there is a very small pin size button next to it.  With an ink pen, just press that micro button for about 3 seconds and the yoga will boot into BIOS.  The DPTF setting is under one of the tabs at the bottom of the menu.  Highlight, select "disable", then tab over to "save and reboot".  That's it!!!

Re: Windows 10 and DPTF

Hello,

 

I have a Yoga 3 11 running on windows 10 and it does not seem that DPTF can be disabled from the bios nor that the fix presented in

https://forums.lenovo.com/t5/Lenovo-Yoga-Series-Notebooks/Hey-Lenovo-what-s-up-with-DPTF-amp-Yoga-ma...

can be done with the 8.1.1060 0.147 version of Intel DPTF (the one that is for download on the lenovo website).

Any suggestion? The only suggestion from the lenovo support was to go back to factory settings and to go back to windows 8 and wait 6 months before upgrading to 10... Really happy to have to call to hear that!

Re: Windows 10 and DPTF

After installing Windows 10 there are several warnings in my system log from DPTF indicating that it has decreased my system speed for 71 seconds.  This seems to correlate with the Windows freezes, so I am going to disable DPTF and see if the freezes go away.
