S730 Yoga Alt-Tab works slow

2019-12-06, 17:15 PM

Often(60% of the time) when I alt+tab there is a delay of second or two before the window switches and it's painfully slow. It happens with laptop keyboard and external keyboards and it happens only when using alt+tab, but if I use finger gestures on the touchpad for switching windows it works flawlessly. It is slow only when using the keyboard shortcut. 

 

I Found this answer:

"""

It looks like it was due to the Lenovo System Interface Foundation driver issue. Uninstalling the driver seems solve the issue. But you can't run other Lenovo software like Vantage etc. But to me, I m fine with it as I don't need. The alt+tab slowness really annoying.

"""

I tried to update this driver but it didn't fixed the problem. Someone knows how to fix it without uninstalling this driver as this advise?

If there is no other option, what can happen if I uninstall this driver? It can affect other things in the system?

Hi ,

 

Welcome to the Community,

 

Regarding the issue, the only times that I encounter the same problem is if I have a lot of thing's running. If CPU and memory usage is high,  then it makes it overall Lag and so affects the response when you tap alt+tab. If you don't have  a lot of Apps running, then check if there is a Windows update running under the Task Manager. It has been discussed also on a similar thread and you can try the steps they have taken. 

 

Hope this helps and let us know how it goes,

 

Jeremy

It happens always not only when I have a lot of apps. It happens also when my CPU usage is 5%.

I saw their advises, but I don't want to uninstall the Lenovo System Interface Foundation driver and that was the only solution that they advised. I search for a better solution.

Hi ,

 

You can always reinstall the Lenovo System Interface Foundation driver as it's available for download on https://pcsupport.lenovo.com/ anytime or uninstall it and install a fresh copy of it and test.

I have noticed this too on my C940 - and I don't understand, either.

 

 

Surely this is something Lenovo should fix and not make us jump through hoops to work out what is gong on ?

If you haven't found this already elsewhere in the Forums; try "Lenovo Vantage - preferences - disable usage statistics", with a restart afterwards. No more slowdown!
