Re: Yoga 13 Lag After updating to Windows 8.1

2013-11-02, 17:06 PM

Surprised Lenovo hasn't put out a fix for this since it has been an issue from the 1st Yogas.  It was figured out in the first weeks of release that with DPTF enabled the CPU was throttled to .87Ghz when in tent or tablet mode.

 

I've had it disabled in the bios for over a year now with no ill effects.  It remained disabled after Win 8.1 update.

This is not The Solution!
Why I should turn off the Dynamic Platform and Thermal Framework ?
Does you means that the thermal framework does nothing?)))
Maybe you offer us to remove Win 8 operating system, then the problem would be solved? )))))))

Re: Yoga 13 Lag After updating to Windows 8.1

I agree. This is something that Lenovo needs to issue a fix for. The way I see it, whether it's Lenovo's fault or not, you need to issue a fix when your computer's key features are crippled after a routine update to an operating system.

 

I was told by repair (my case had been escalated from the call center to somewhere else in Lenovo) that I can't EXPECT my system to work on anything other that Windows 8, ie. what the computer shipped with. So basically, any service packs or OS updates, be it 8.1 or future updates, leave me on my own. Is this common practice? I can understand if I updated to Windows 9 (though I've never, ever had a problem with any computer updating to a subsequent OS in the past), but wouldn't 8.1 still count as Windows 8? I mean if they (Lenovo) are issuing driver updates for 8.1, I can't see how they figure I'm on my own. That would be a poor business practice. Someone please clarify this for me.

 

I'm debating even sending the system in. I need to if I want to downgrade to 8.0 (recovery key issues), but they are saying that, should Lenovo not issue a real fix, I'm left unable to update my OS.

 

One thing I am sure of: if this is indicative of their mentality across product lines, I will never buy another Lenovo computer.

mshakurov "This is not The Solution!"

 

I did not claim this would be a solution for you.  It did fix the thottling issue for me when in tent or tablet mode..

 

mshakurov "Does you means that the thermal framework does nothing?)))"

 

DPTF throttles the CPU when in tent or tablet mode....so yes it does something.

 

mshakurov "Maybe you offer us to remove Win 8 operating system, then the problem would be solved? )))))))"

 

Could you be a little more rude....I was just trying to help.

Re: Yoga 13 Lag After updating to Windows 8.1

Lenovo honestly told you, that a convertible for 1400 Euro, that was bought in August this year (in my case) will not be supported under Windows 8.1. Honestly, this could only be a bad joke.

This is not a device from some discounter or an android device.

 

I decided to buy a Lenovo because i thought that i buy a high qualitiy product which makes me happy a long time. But if i read something like this i really have doubts, that this was the right decsion.

If Lenove won't give us a fix for this issue this would be the last Lenovo Computer i bought. For sure.

 

Currently i can't recommand anybody to buy a Lenovo computer.

  

FRUSTRATED!!!!!

Yes, I was told that (American Yoga owner here). Not that it wouldn't support it, but that I couldn't expect anything other than what it shipped with to work properly.

 

I could understand this if I owned a 7 year old laptop and tried to upgrade to Windows 10. I wouldn't expect to be able to install it. But this is essentially a service pack.

 

I wonder if this problem affects the Yoga 2? Or did that ship out of the box with 8.1? That would be ironic.

Re: Yoga 13 Lag After updating to Windows 8.1

I tried disabling the DPTF and this did not resolve my problem, although I did figure out what the problem was and have resolved it in my case.  

 

For me, if I ran task manager and looked at CPU consumption it was around 30-40% with nothing running. However, if I added up the cpu consumption of what was listed it was only 10% or so. However, I noticed copies of Winodws Backup continually loading and unloading (sdclt.exe).  3 or 4 copies seemed to always be running. After some research, I found references to a little known bug in the windows 8.1 upgrade that a few people have reported relating to windows backup.

 

It can be resolved by looking in the windows Task Scheduler under 'Microsoft\Windows\WindowsBackup\ConfigNotification' which starts the following process

%systemroot%\System32\sdclt.exe /CONFIGNOTIFICATION

 

The workaround is to either remove or disable this task and reboot your system.  It worked for me, have no idea if any of you all are in the same boat so YMMV, but in my case it was like pushing a turbo button.

Re: Yoga 13 Lag After updating to Windows 8.1

I have been experimenting with disabling various programs and services (Lenovo Transition etc) but never really found any solution that didn't mess up something else instead... However, turning off the DPTF seems to have solved all issues without any apparent drawbacks, now I also set everything else back to default settings. Things that got resolved:

 

1. Laggy performance with the onscreen keyboard

2. Slow page load times on IE

3. Slow startup

4. Horribly choppy audio when connected to bluetooth speaker

 

Now my computer feels brand new and everything works great! Makes you wonder why they pre-install a feature (DPTF) when its only function seems to be to make your computer suck.

Re: Yoga 13 Lag After updating to Windows 8.1

I am experiencing the same issues. On TWO DIFFERENT YOGAs, I have upgraded to Windows 8.1 to see extremely **bleep**ty performance. Massive lag, choppy video, all the complaints mentioned here. I upgraded all the drivers listed as Yoga compatible. I upgraded my BIOS to v55. I disabled the thermal framework (helped with the massive lag, but a persistent lag still exists). I did everything I could. Then I downgraded back to Windows 8.0.

 

This is insanity. I bought my Yoga 13 in September of THIS YEAR. That is right, two months ago, and my computer is already out of date and unable to be upgraded to Windows 8.1. I will never buy another Lenovo.
