Yoga Pro 2 Major Performance Problems: Lag, Keyboard, Video, Sleep

2015-08-14, 13:34 PM

I'm having a number of issues with my Yoga Pro 2, some perhaps caused by Windows 10, but I'm not sure.

  1. After my computer has been asleep overnight, or for hours at a time, it almost always lags. Videos are choppy, my mouse lags as I drag it; everything runs slow. It's acting as if memory were at 100% performance, but it's generally around 60%, with CPU usage around 20-40%. I've upped the virtual memory to match the computer's ram (8,000mb), whihc solved the choppy video playback when I had windows 8.1. But now it's not just video, it's the whole computer. I keep having to restart the computer to get it running normally again. 
  2. When I put my computer to sleep, sometimes the keyboard it shut off when I try to type in my password and I have to hit the f4 button to turn the keyboard back on.
  3. The computer goes to sleep after 5 minutes of not touching it when the computer it plugged in. I have made sure all the advanced power settings are set correctly. When it's plugged in, it's not supposed to go to sleep for an hour without touching it. 

The biggest problem at this point is the lag. I work many part time jobs online and I need to be able to keep a lot of windows open since I don't finish them in one day usually. Having to close everything and restart really kills my productivity.


Does anybody else have the same problem, and does anyone have a solution to these issues? I've installed all the Windows 10 drivers I could from the Lenovo support page, and many of them said I already had the latest version and the version on the lenovo site would be an older version (I found that weird).

It sounds like a problem associated with the Intel DTFP driver. Start up Task Manager. Go to the Performance tab. Is the computer trapped at 700mhz? That's your problem. Check out the other threads on this issue to learn more.


The current solution beyond going to the bios and disabling DTFP is to restart your computer.
