Yoga 710 14 IKB Issue- Left + Right Click Do Not Work After System Crash.


Several days ago my laptop (As per title) crashed (I had dozens of Chrome tabs open + MS Word). After restarting, I lost right click completely. Left click will be unresponsive upon start up but eventually after some time (2-3 minutes) comes back to life. However it often then ceases to work soon after for no reason. So left click only works intermittently.


I am almost certain it cannot be a physical hardware issue as the touch pad + click function worked perfectly before, then after a system crash it became completely unresponsive.


I am stuck navigating using the touchscreen, tab/enter/arrow keys and the keyboard shortcut for right click. An external USB mouse works perfectly fine and I can left+right click normally, but this is not a long-term solution.


This is very annoying. My laptop is out of warranty, as I purchased it new and have been using it since late 2016/early 2017.


So far every attempt to resolve this has not worked, but so far I have tried:

1- Updating my Elan Device Drivers through Device Manager

2- Attempting to 'Defrag' Windows through it's inbuilt tools

3- Full Reinstall of Windows (Wiping all files completely)

4- Uninistalling/removing Elan Mouse Device completely through Device Manager, restarting, then allowing it to automatically reinstall.

5- Shutting down the system, holding the power button for 30 seconds (I read this can help clear out bugs, someone had some luck with it rectifying their track pad right click issues but didn't help me)

6- Installing latest Elan Device Drivers for my model laptop directly from Lenovo's website

7- Installing 'Lenovo Solution Center', doing a full system scan (Laptop shut off ~50% way through a full scan for no reason, on start up said there was no issues. I did another targeted scan on the Motherboard (As I heard it can be a bug here and not a mouse problem), PCI Express and Storage Devices) which were all passed.

8- Updated BIOS to latest version to try and see if I could use the mouse cursor/click to determine if it's a Windows problem or something else, but Lenovo's BIOS has no mouse support at all, only buttons.


I am completely stumped. The only thing I haven't tried is removing the back panel screw's, popping the shell apart with a pry-tool and physically disconnecting the battery as per these instructions. But as my battery is internal I'd like to avoid that if possible and #5 was a similar process.


Can someone please help me? It'd be great to resolve this, especially so other people who face similar problems can use this as an example. Disappointing how a laptop which is hardly old at all faces such a fatal error with seemingly no cause, with seemingly no solution.

Update 5/11/2018.


Still no ideas from anyone? I have not been able to resolve this.

My only solution was to buy a Chromebook.

Lenovo laptop has been relinquished as an expensive paperweight. 

And we're back...

Move delayed but still coming
