Ideapad 720S-15IKB touchpad delay and nonresponsive bug

My touchpad input lags a bit  and scrolling is slow and not consistent. However, if I disable the touchpad with F6 and re-enable it, the touchpad becomes responsive and acts "normal", for a whole minute that is. Then it goes beack t o being slow and unresponsive.

I've been using my new laptop (720S-15IKB) for about 15 minutes and I'm already infuriated by this bug. Definitely returning it ASAP if there's no sign of a fix?

Hello,

 

I have exactly the same problem. It is very annoying, touchpad delay is appearing randomly. I don't know what causes that problem.

Bios, Windows 10 and drivers are all up to date...

 

Lenovo please fix it!

Lenovo confirmed my laptop as faulty and did a return/refund. I bought a different model laptop instead.

I need to return mine as well. Did you have to go through tech support to initiate the return ? I am past my 30 day. Hope i am not screwed.

I am having this exact issue and use the same 'workaround' to temporarily fix it (disable and re-enable the touchpad with the F6 key). I did return my unit and got a new one but the issue is present on this one as well. The touchpad seems to be using a generic windows driver so maybe that's the issue. I couldn't find a driver for this laptop on lenovo's support page.

Really bummed out as this is an otherwise great laptop and i never use a mouse with laptops.
