I've had my y520 for around a month or so. I noticed a few days after I got it that some things seemed wonky. My touchpad randomly stops working whether I am playing a game or just browsing the web. I have to restart the laptop to get it to start again.
The other issue is the fan seems to run almost constantly. I can have no programs open and no background programs running and the fan will be whirring loud enough for me to hear it.

Thanks for using the Lenovo forums.
Try a static discharge for this, it may help to resolve the issue or at least get rid of any built up static on the motherboard.
(If the battery is internal, please just skip the remove/replace battery steps.)
1. Turn the unit off
2. Remove the battery and the Mains adapter
3. Press and hold the front power button for 30 seconds
4. Replace the battery and the Mains adapter
5. Turn the unit on as normal
For the fan, I think you could try to use some sort of fan control software, that should help with when to have it run.
Hope this helps, let us know how you get on.

I have the Lenovo Legion Y720 and I'm having the same Trackpad issues as the OP. Sometimes for no reason after I boot up my laptop, after about 1 minute or so, the trackpad stops working. I've tried using the "Fn+F6" function on my keyboard to disable and enable the trackpad, but that doesn't help at all. I want to know how in the world it could be a battery issue? Me and the OP's laptop are only like 1 month old and the batteries should still be in perfect condition. (even if it is a battery issue, we'd just RMA our laptops because it's only a month old.) Also what in the world do you mean by trying a static discharge?! How and why would someone try this?! This must be a software issue anyways.
(edit) nevermind, i'm an idiot. i didn't know what you meant by "static discharge".

I've had this problem for a while now. Mostly it's the whole touchpad that stops working and more rare occasions scrolling feature stops working. If it's the scrolling thats problem then it's usually sufficient to go the elan settings and click apply and ok. When the whole touchpad stops working then only possible solution so far is to reboot. I've reinstalled the drivers several times and this just keeps coming back.
One curios thing I found is that the touchpad icon that is in the icon tray has a blue mark in the middle of it. It indicates as if you had your finger on it the whole time. I've made sure that there aren't any dust or anything else whatsoever. By pressing Windows key + L and logging in again I got rid of the blue spot but the problem persist.

I have a similar issue with the touchpad stopping working on my Lenovo Legion Y720. I've found a quicker way to fix this compared to reboot, although not a proper fix. Just put the computer in sleep mode, or shut the laptop and reopen it. It should be working again.

I have the same problem on Y720 - also touchpad suddenly is not working. Sleep mode is helping to activate it back. Also I have one more problem - one USB slot suddenly stopped to work and my laptop is only one month old....

Same problem with the touchpad here, drivers are up to date, installation / uninstallation does not change anything.
Laptop bought in January and from the beginning the problem is present.
@Lenovo: Thank you for providing us with a viable solution, because considering the price of the machine it is all the same inadmissible to have this kind of problem just out of the box.

This was the solution to my problem with the touchpad on my Lenovo Yoga 700 laptop (disabled automatically after sleep). I removed the device with the question mark in the Device Manager (run devmgmt.msc), restarted the computer, and now, the touchpad always works, even after the laptop goes to sleep.

Sleep mode is working and back. But it's a shame that Lenovo does not react to this problem.
The problem is present from the begining for me. It has been 6 months but no fix.

Still no news on this subject? I usually use Logitech mouse, but when using the touchpad it's really annoying when it randomly stops working. Any idea if this is a software or hardware problem? So far the only way to get it working again is a restart or going to sleep and waking up the pc.
