Re: Yoga 3 Pro processor runs slow

There's another fix - if you go into the bios menu, and exit without changes, the processor "resets" itself back to normal speed. I suspect the issue is that it gets "locked" into a slow speed after sleep.

Re: Yoga 3 Pro processor runs slow

I survive with a Core M processor Lenovo Yoga by doing the following:

As the CPU gets hotter it slows down, so keep the CPU cool. I do this by using Balanced power setting or by using simple cooling techniques - pop four or so dice underneith the laptop to get some convection cooling going. Or buy an inexpensive fan-equipped laptop board. Or buy an inexpensive silent USB fan with a flexible neck

Use Edge and not Chrome for streaming video such as YouTube, as it uses more GPU and less CPU and hence runs cooler, faster, and smoother.

I recommend that you go into settings and choose which apps can run in the background. No point letting pointless apps use the CPU when you are not using them.

Re: Yoga 3 Pro processor runs slow

I think this is  a design failure. I too have this problem. If I plug in and run in performance mode it will run almost as good as my 10 yo Dell 700m running XP.   Ran benchmark it was slower than my mother-in-laws Dell running an old Celeron.

Should have returned this the minute I realized how bad it was. No way to upgrade the processor on these? Mine looks brand new cause I never used it due to its slow speed.

Re: Yoga 3 Pro processor runs slow

HERE IS SOLUTION for Lenovo Yoga 3 Pro slow core-m processor.


Go to Bios and disable DPTF 

(go to Bios by turning PC off, then press small recovery button on right edge of laptop)


(Dynamic Platform and Thermal Framework is a "solution to help enable thin, quiet, and cool platform designs". But as we can see it works awful)


Your laptop will be much hotter, but it will work like a normal PC, capable of playing video on YouTube in Chrome 1080p 60 fps (on high performance mode, which you can choose clicking on battery icon in tray)


Before disabling:

Frequency on high load drops to 0.5 - 0.8 GHz, CPU usage stays on 20-70%. Laptop slows down extremely and become unusable. Can barely play any youtube video, extremly slow.


After disabling:

Frequency on high load stays on 1 - 2.6 GHz, CPU usage up to 100%. Laptop works as a normal PC, never slowing down. The bottom cover of the laptop becomes hot.


also i updated bios, not sure if it works on previous bios version.
